Applicable Models: All

(Write-only) Initiates the measurement of the specified calibration standard. Executing this command with an unnecessary standard has no affect.

The measured data is stored and used for subsequent calculations of error correction coefficients. All standards must be measured before a calibration can be completed.  Any measurement can be repeated until the SENS:CORR:COLL:GUID:SAVE command is executed.

Query the user prompt description using SENS:CORR:COLL:GUID:DESC?

Query the required calibration steps using SENS:CORR:COLL:GUID:STEP?

Parameters

<ch>

Channel being calibrated, depending on the CHAN:MODE setting.  If unspecified, value is set to 1.

STAN<n>

Choose from:STAN1, STAN2, etc. through STANn where n is the number of cal standard connection steps for the calibration.

Note: You do not necessarily have to invoke these connection steps in sequential order, but you must issue this command for all of the steps to be able to complete the calibration.

[sync]

Optional argument. Choose from:

SYNChronous - blocks SCPI commands during standard measurement (default behavior).

ASYNchronous - does NOT block SCPI commands during standard measurement.

Applicable Models: All

(Read-Write) Specifies a DUT connector type for every port during the Guided Calibration procedure. Valid DUT connector names are stored within calibration kits. Some cal kits may include both male and female DUT connectors. Therefore, specifying the DUT connector gender may be required.

The VNA remembers previous Guided Cal settings. Therefore, for completeness, unused ports can either be defined as "Not used" or use the SENS:CORR:COLL:GUID:ABORt command to clear all ports. The ABORt command is a more thorough approach and more convenient. See Guided Cal examples.

• A single port with a valid <conn> name indicates  a 1-Port calibration will be performed.  

• Two ports with valid <conn> names indicate either a 2-Port SOLT or TRL calibration will be performed depending on the standards definition found within the cal kit and the capability of the VNA.

• Three ports with valid <conn> names indicate a 3-Port calibration will be performed, and so forth.

Parameters

<ch>

Channel being calibrated, depending on the CHAN:MODE setting.  If unspecified, value is set to 1.

<pnum>

Applicable Models: All

(Read-Write) Sets and returns the measurement data for a specified measurement parameter of a particular step of a guided cal (and for a specific state of an ECal if the step is an ECal step). The measurement data is complex real-and-imaginary pairs where the number of points is the current number of points on the channel, and is in ASCII or binary format as dictated by the current setting of the FORMat:DATA command.

The query returns measurement data once it has been uploaded. The Cal Wizard will also perform the acquisition as in a normal calibration an then use the query to see the data per ECal state.

Note: This command only applies to cals of standard S-parameter channels.

Parameters

<ch>

Any existing channel number. If unspecified, value is set to 1.

STAN<n>

Choose from:STAN1, STAN2, etc. through STANn where n is the number of cal standard connection steps for the calibration.

Note: You do not necessarily have to invoke these connection steps in sequential order.

<meas parameter>

Measurement parameters for standard S-parameter channels.

<data>

Measurement data to upload.

[<ECal state num>]

(Read-Write) Specifies the Ecal Kit for Ecal Calibration. This is a new command that specifies the ECal kit to be used in the new 1-shot ECal execution command.  If not specified, the 1-shot command will internally select the top one from the connected ECal kits (like the basic cal and start cal dialogs are doing.)

The top ecal kit in the list can be ordered either by an internal module number or alphabetically.  This default selection will allow the user to use generic test code but only if there is only one ECal connected.

Parameters

<ch>

Channel to be calibrated, depending on the CHAN:MODE setting.  If unspecified, value is set to 1.

<ecal kit>

Ecal kit to be used for the specified port. Case-sensitive.

Include the characterization name in the <kit> string. Use SENSe:CORR:COLL:GUID:CKIT:CAT? to read the list of characterizations available in the module and in VNA disk memory.

If two or more identical ECal modules are connected to the VNA, the serial number must be included to distinguish the ECal modules.

(Write-only) Computes the error correction terms, turns Correction ON, and saves the calibration to an existing, specified Cal Set.

The cal acquisition process does not conclude as with the SAVE command. This command leaves the cal acquisition in memory to allow re-measuring/re-computing. To conclude the cal acquisition process, use the SENS:CORR:COLL:GUID:ABOR. command.

Learn all about Cal Sets.

Note: This command is NOT supported for application channels (Gain Compression, SMC/VMC, Noise Figure, IMD and so forth). Use SENS:CORR:COLL:GUID:SAVE and save to a cal register. You can then use SENS:CORR:CSET:COPY to copy the cal register to a named Cal Set.

• Use this command instead of specifying the optional name or GUID argument in SENS:CORR:COLL:GUID:INIT.

• Use SENS:CORRection:CSET commands to get names of existing Cal Sets.

• The cal data is also saved to the channel Cal Register.

• If all of the required standards have not been measured, the calibration will not complete properly.

For Calibrate All Channels

When this command is used during a Cal All session, the <cal set name> argument sets the User Cal Set prefix.  All generated Cal Sets will be preceded with this string name.

• Cal Set prefix can also be set using SYST:CAL:ALL:CSET:PREFix. When the Cal Set prefix has already been set with SYST:CAL:ALL:CSET:PREFix, this command overwrites it.

• When <cal set name> is an empty string, a User Cal Set will not be saved.  Only Cal Registers will be saved.

Parameters

<ch>

Channel being calibrated, depending on the CHAN:MODE setting.  If unspecified, value is set to 1.

<cal set name>

String - Name of an existing Cal Set to be overwritten.

<port1>

First port of the port pair to be calibrated.

<port2>

Second port of the port pair to be calibrated.

<thruType1[,thruType2]>

(String) Thru methods for port pair, enclosed in a single pair of quotes.  NOT case-sensitive.

thruType1  Calibration Thru method. Choose from:

• Defined Thru  Measures a Thru for which there is a stored definition in the Cal kit of the lowest-numbered port of the pair. For example, if the port pair is 1,2, then the cal kit for port 1 MUST contain a Defined Thru.

• Zero Thru  Measures a Zero length Thru, also known as Flush-Thru.

• Undefined Thru  (Also known as Unknown Thru)  A Thru type for which there is NOT a stored definition in the Cal Kit. Valid ONLY for SOLT cal type.

• Undefined Thru using a Defined Thru  (ECal modules ONLY) Measures the internal Thru as an Unknown Thru.

thruType2  Optional argument. Use ONLY when Adapter Removal Cal is specified for the pair using SENS:CORR:COLL:GUID:PATH:CMEThod. When specifying ThruType2, this is the only valid argument: "Defined Thru, Defined Thru"

Examples

SENS:CORR:COLL:GUID:PATH:TMEThod 2,3,"Zero Thru"
sense:correction:collect:guided:path:tmethod 2,3,"Defined Thru,Defined Thru"

Query Syntax

SENSe<ch>:CORRection:COLLect:GUIDed:PATH:TMEThod? <port1>,<port2>

Always returns two parts:

If the second part of the string is empty, adapter removal is NOT being performed.

If the string is "Defined Thru, Defined Thru", adapter removal IS being performed.

Return Type

String

Default

The most accurate Thru method for the current cal.

Applicable Models: All

(Read-Write) When enabled, and the following conditions are met, the user's existing source power calibration array will be used when acquiring calibration standard data:

• The user is performing a vector calibration only (no power).

• A valid source cal is present in the channel being calibrated.

• The user has elected to enable this feature (via GUI or SCPI).

Note: This command MUST be sent AFTER setting up the connectors and kits for the calibration session. Otherwise, the firmware can not determine which ports are going to be used in the calibration session. Therefore, it can not check if there is an applicable power calibration, because power calibrations are per port.

If this command is sent before setting connectors and kits, the following error is displayed:

   +3068,"The request to use existing source cal array during calibration was refused."

Parameters

<ch>

Channel being calibrated, depending on the CHAN:MODE setting.  If unspecified, value is set to 1.

<bool>

Choose from:

OFF (0)   Do not use existing source power calibration array when acquiring calibration standard data:

ON (1)   Use existing source power calibration array when acquiring calibration standard data:

(Read-Write) Specifies the behavior for guided cal steps that involve a sliding load in a cal that is about to be performed. Send this command BEFORE sending the Guided INIT command.

Although the term 'Preference' is used in the command, this is NOT a VNA preference. This setting does NOT survive instrument preset or reboot. It remains ONLY for the duration of the Guided Cal.

Parameters

<char>

Behavior when measurements of sliding load are acquired. Choose from:

DIALog - The Sliding load dialog box appears when the acquire command is received for a sliding load step.  All slide positions are measured (with a user-interface prompt) from a single invocation of the acquire command.

ITERate - Each invocation of the acquire command for a sliding load step measures a single slide position and increments the slide position counter. No Move Sliding Load prompt is presented on the VNA screen.

Examples

SENS:CORR:COLL:GUID:PREF:SLID ITER

(Write-only) Completes the guided cal by computing the error correction terms, turning Correction ON, and saving the calibration to a Cal Set. If all of the required standards have not been measured, the calibration will not complete properly.

Learn all about Cal Sets.

Parameters

<ch>

Channel being calibrated, depending on the CHAN:MODE setting.  If unspecified, value is set to 1.

[bool]

Optional argument. If unspecified, the default behavior is the current VNA preference setting of SENSe:CORRection:PREFerence:CSET:SAVE.

OFF (0)   Save cal data ONLY to a Cal Register.

ON (1)  Save cal data to a Cal Register and a User Cal Set. The filename is automatically generated.

• For application channels (Gain Compression, SMC/VMC, Noise Figure, IMD and so forth), this command saves ONLY to a Cal Register. Use SENS:CORR:CSET:COPY to copy the cal register to a named calset.

• For a Calibrate All Channels session, this argument is ignored.  Instead, use SYST:CAL:ALL:CSET:PREFix.

(Write-only) Completes the guided cal by computing the error correction terms, turning Correction ON, and saving the calibration to an existing, specified Cal Set. This command performs the same function as SENSe:CORRection:COLLect:GUIDed:SAVE, except this command allows the name or GUID of the Cal Set to be specified.

Learn all about Cal Sets.

Note: This command is NOT supported for application channels (Gain Compression, SMC/VMC, Noise Figure, IMD and so forth). Use SENS:CORR:COLL:GUID:SAVE and save to a cal register. You can then use SENS:CORR:CSET:COPY to copy the cal register to a named Cal Set.

• Use this command instead of specifying the optional name or GUID argument in SENS:CORR:COLL:GUID:INIT.

• Use SENS:CORRection:CSET commands to get names or GUIDs of existing Cal Sets.

• The cal data is also saved to the channel Cal Register.

• If all of the required standards have not been measured, the calibration will not complete properly.

For Calibrate All Channels

When this command is used during a Cal All session, the <cal set name> argument sets the User Cal Set prefix.  All generated Cal Sets will be preceded with this string name.

• Cal Set prefix can also be set using SYST:CAL:ALL:CSET:PREFix. When the Cal Set prefix has already been set with SYST:CAL:ALL:CSET:PREFix, this command overwrites it.

• When <cal set name> is an empty string, a User Cal Set will not be saved.  Only Cal Registers will be saved.

Parameters

<ch>

Channel being calibrated, depending on the CHAN:MODE setting.  If unspecified, value is set to 1.

<cal set name or guid>

String - Name (or GUID of an existing Cal Set) of Cal Set to be saved. If the Cal Set already exists, it will be overwritten. If specifying a GUID, curly brackets must be included.

See Calibrate All Channels note (above).

(Write-only) Clears ALL flags for channels to sweep during calibration. To flag a channel, see SENS:CORR:COLL:GUID:SWE:CHAN.

This is equivalent with SENS:CORR:COLL:SWE:CHAN:AOFF.

Examples

SENS:CORR:COLL:GUID:SWE:CHAN:AOFF

sense:correction:collect:guided:sweep:channel:aoff

Default

Not applicable

Applicable Models: All

(Write-only) Specifies an alternate channel (other than the calibration channel) to be viewed while using the calibration wizard.

When this command is sent, the <cnum2> channel is 'flagged' to be swept during calibration.  

The flag is cleared when the channel is deleted, if the Measurement Class is changed, or if all measurements are deleted from the channel.

If the same channel number is recreated, this command must be sent again to sweep the channel during a calibration.  The flag is NOT saved with an instrument state.

A Preset or Instrument State Recall deletes the channel.

This is equivalent with SENSe:CORRection:COLLect:SWEep:CHANnel.

Note: This command is intended to be used in conjunction with the interactive calibration wizard.

Parameters

<cnum>

The channel to be calibrated.  If unspecified, value is set to 1.

<cnum2>

The channel to sweep when waiting to measure a standard.

This channel must already exist with at least one measurement in the channel. If this channel is in continuous sweep mode, it must have the same attenuator settings and path configuration (PNA-X only).

<bool>

Channel sweep state. Choose from:

ON (or 1) - Sweep the channel during calibration.

OFF (or 0) - Do NOT sweep the channel during calibration.

(Write-Read) Sets and returns the ON/OFF state which determines if the calibration that is about to be performed will support Dynamic Uncertainty for S-Parameters (Opt. S93015A/B).

Dynamic Uncertainty for S-Parameters is supported ONLY for calibrations on standard S-Parameter channels. Calibrations performed with that feature enabled do NOT support the use of ALL traditional GUIDed calibration commands. 

Then these existing commands are used for performing calibration:

SENSe<ch>:CORRection:COLLect:GUIDed:CKIT:PORT<pnum>[:SELect] <kit>

SENSe<ch>:CORRection:COLLect:GUIDed:INITiate[:IMMediate] [string][, bool][,char]

SENSe<ch>:CORRection:COLLect:GUIDed:DESCription? <stepNum>

SENSe<ch>:CORRection:COLLect:GUIDed:ACQuire <stepNum>

SENSe<ch>:CORRection:COLLect:GUIDed:SAVE[:IMMediate]

where these commands might also optionally be used in performing the calibration:

SENSe<ch>:CORRection:COLLect:GUIDed:CKIT:PORT<pnum>:CATalog?

SENSe<ch>:CORRection:COLLect:GUIDed:ABORt

SENSe:CORRection:PREFerence:ECAL:ORIentation[:STATe] <ON|OFF>

SENSe:CORRection:PREFerence:ECAL:PMAP <module>, <string>

Dynamic Uncertainty must be enabled using this command before starting the calibration procedure because this command controls the way connectors and calkits are assigned to ports during calibration. Therefore, this command must be enabled before any of the following commands to ensure that the connector and calkit settings will be set/queried correctly:

SENSe<ch>:CORRection:COLLect:GUIDed:CKIT:PORT<pnum>[:SELect] <kit>

SENSe<ch>:CORRection:COLLect:GUIDed:CKIT:CATalog?

SENSe<ch>:CORRection:COLLect:GUIDed:CONNector:PORT<pnum>[:SELect] <conn>

SENSe<ch>:CORRection:COLLect:GUIDed:CONNector:CATalog?

Parameters

<bool>

Enable ON/OFF state. Choose from:

ON or 1 – The next calibration INITialized for the channel will support Dynamic Uncertainties for S-Parameters.

OFF or 0 -- The next calibration INITialized for the channel will NOT support Dynamic Uncertainties for S-Parameters.
