Default

Not Applicable

(Read only) Returns a list of valid connectors based on the connector descriptions of the available cal kits. Use an item from the returned list to specify a connector for SENS:CORR:COLL:GUID:CONN:PORT

Here are the more common connector types:

Examples

SENS:CORR:COLL:GUID:CONN:CAT?
Returns:

Type N (50) female, Type N (50) male, APC 7 (50), 3.5 mm (50) male, 3.5 mm (50) female, User Connector A

Return Type

Comma separated string values

Default

Not Applicable

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

The VNA remembers previous Guided Cal settings. Therefore, for completeness, unused ports should be defined as "Not used". 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>

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

<conn>

String - DUT connector type to connect with VNA port <pnum>. Case-sensitive.

Examples

'Specifying a 2-port cal (1 & 2) on a 4-port VNA

SENS:CORR:COLL:GUID:CONN:PORT1 'Type N (50) female'
SENS:CORR:COLL:GUID:CONN:PORT2 'Type N (50) male'
SENS:CORR:COLL:GUID:CONN:PORT3 'Not used'

'Returns:
Connect APC 7 Open to port3

Return Type

String

Default

Not Applicable

(Write only) Execute the Ecal calibration with specified the Ecal by SENS:CORR:COLL:GUID:ECAL:SEL. If ECal module is not specified, the first Ecal in the list is used. One item that we discussed is that this command needs to be overlapped. That's because it can be quite slow to finish an ecal, and slow operations need to be implemented using overlapped SCPI. Otherwise, the client will time out and will be unable to poll for completion. So, the command must be followed with either a *OPC? or a *OPC and serial poll.

Parameters

<ch>

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

<cal method>

String  Calibration Method.

SOLT: using defined through

SOLR: using undefined through

ERESponse: Enhanced Response

<port list>

Array  Port number to be calibrated. If enhanced response (ERESponse) is selected, the first port number is the stimulus port and the second port number is the response port.

[calset]

Optional argument. Cal Set name

If NOT specified, behavior depends on the SENS:CORR:PREFerence:CSET:SAVE setting.

If specified, choose an existing Cal Set, either by name or by GUID.

• By Cal Set name: include quotes.

• By Cal Set GUID in the form: "{GUID}"; including quotes and curly brackets.

• Query all Cal Set GUIDs with SENS:CORR:CSET:CAT?

An error is reported if the Cal Set is not found.

The Cal Set is either supplemented or overwritten depending on the method, connectors, and ports selected. Learn more about Cal Sets.

Examples

' Full 2 port cal with defined through for ports 2 and 3

SENS:CORR:COLL:GUID:ECAL:ACQ SOLT,2,3

' Enhance Response Cal for ports 4 (Stimulus) and 1 (Response)

SENS:CORR:COLL:GUID:ECAL:ACQ ERES,4,1

Default

Not Applicable

(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 determined in two ways:  by an internal module number that is dependent on the order in which the ecals are enumerated on the USB.  Or it could be an alphabetical sorting by name.  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.

Examples

 ' Standard ECal modules

Query Syntax

Not Applicable

Default

Not Applicable

(Read-Write) Specifies the calibration method for each port pair.

Note: Sending this command will overwrite the PNAs SmartCal determinations for the most accurate cal method for your connector settings and Cal Kits.  Send this command ONLY if you have a deliberate reason for overwriting the SmartCal logic. You can send the query form of this command to learn the cal method determined by SmartCal.

See Thru Pairs Sequence to learn how to send this and other Thru commands.

After sending this command, send the query form to be sure that the command was accepted. If not, then the chosen Cal method is not compatible with the specified Thru method. For example, if the specified Thru method is Unknown Thru, an attempt to set Enhanced Response Cal should be rejected.

Learn more about Thru Methods.

Parameters

<ch>

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

<port1>

First port of the pair to be calibrated.

<port2>

Second port of the pair to be calibrated.

<caltype1[caltype2]>

(String) Cal type for the port pair, enclosed in a single pair of quotes.  NOT case-sensitive.

caltype1 Choose from:

• TRL

• SOLT

• QSOLTN

• EnhRespN

For the last two arguments, replace N with the port to be used as the source port, which MUST be one of the port pair.

caltype2  Optional argument. Use only when performing an adapter removal cal on the pair. This argument specifies the Cal type on the second port.  Caltype1 then specifies the Cal type of the first port.

Choose from the same arguments as caltype1.

Examples

SENS:CORR:COLL:GUID:PATH:CMEThod 2,3,"QSOLT2"

sense:correction:collect:guided:path:cmethod 2,3,"solt,trl"

Query Syntax

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

If only one caltype is returned then its NOT adapter removal.

Return Type

String

Default

The most accurate Cal method for the current cal.

(Read-Write) Specifies the calibration THRU method for each port pair.

Note: Sending this command will overwrite the VNAs SmartCal determination for the thru method.  Send this command ONLY if you have a deliberate reason for overwriting the SmartCal logic.  You can send the query form of this command to learn the THRU method determined by SmartCal.

See Thru Pairs Sequence to learn how to send this and other Thru commands.

Learn more about Thru methods.

Parameters

<ch>

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

<port1>

First port of the port pair to be calibrated.

<port2>

Second port of the port pair to be calibrated.

<thruType1>

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

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>

(String) Thru methods for port pair.

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.

If the string is set to "Zero Thru", query is returned as "Defined Thru"

Return Type

String

Default

The most accurate Thru method for the current cal.

(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

See example program

Query Syntax

SENSe<ch>:CORRection:COLLect:GUIDed:PREFerence:SLIDingload?

Return Type

Character

Default

DIALog

(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.

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.

Examples

SENS:CORR:COLL:GUID:SAVE
sense2:correction:collect:guided:save:immediate 0

Query Syntax

Default

Not Applicable

(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.

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 calset.

• 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 to be overwritten. If specifying a GUID, curly brackets must be included.

See Calibrate All Channels note (above).

Examples

SENS:CORR:COLL:GUID:SAVE:CSET "{2B893E7A-971A-11d5-8D6C-00108334AE96}"
