SENSe<cnum>:CORRection:CSET:DATA <eterm, portA, portB,>[<rec>,] <block>

Applicable Models: E505xA with VNA ports

(Read-Write) Read or Write a specific error term from/to the Cal Set currently attached to the specified channel. (For Advanced Users). The command can be used only for the error terms listed. See SENS:CORR:CSET:ETERM to get and put error term data using a string argument for all error terms.

Parameters

<cnum>

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

<eterm, portA, portB>

Error Term, Port pair of the specified error term.

Although not all error terms use two port numbers, two are required by the VNA in all cases. Each port number must be between 1 and the number of ports on the VNA.

EDIR - directivity

portA: the port at which directivity is measured.

portB: Not used, but must be a valid VNA port number.

ESRM - source match

portA: the port at which source match is measured.

portB: Not used, but must be a valid VNA port number.

ERFT - reflection tracking

portA: the port at which reflection tracking is measured.

portB: Not used, but must be a valid VNA port number.

ELDM - load match

portA: the port at which load match is measured.

portB: the source port.

Load match is measured with a cable connected between the measured port (portA) and the source port (portB).

The cal system requires that the complete matrix of loadmatch arrays be filled. In most cases you can measure loadmatch once at a port, driven by any other port. Then use that data for all variations of the receive port. (The exception is the 3-port VNA models, which requires the loadmatch-measured port to be driven by every other port.)

For example: Measure the loadmatch at port2 while driving port1. Then upload this same data to the following arrays:

ELDM,2,1,<data>

ELDM,2,3,<data>

ELDM,2,4,<data>

ETRT - transmission tracking

portA: the receive port

portB: the source port for this measurement

EXTLK - crosstalk

portA: the receive port

portB: the source port for this measurement

ERSPT - response tracking.

portA: Not used, but must be a valid VNA port number.

portB: Not used, but must be a valid VNA port number.

ERSPI - response isolation.

portA: Not used, but must be a valid VNA port number.

portB: Not used, but must be a valid VNA port number.

<rec>

<string> - Specify the VNA receiver for which the Eterm applies.

Required ONLY when Eterm is response tracking (ERSPT) or response isolation (ERSPI).

Logical receiver notation is allowed.

A full 4-port calibration requires the following terms be uploaded:

SENSe<cnum>:CORRection:CSET:FLATten <string>

Applicable Models: E505xA with VNA ports (Write-only) When a Cal Set that was produced by a calibration has been interpolated or otherwise modified (for example, by Fixturing operations) this command saves the modified Cal Set to the VNA hard drive so that it can be reused. There is no User Interface equivalent for this command. Background When a Cal Set is selected for use by a channel, the channel reads the Cal Set from disk (primary Cal Set). If the channel aligns perfectly with the Cal Set, the primary Cal Set is used directly. In this case, the active Cal Set is the primary Cal Set. When processing occurs on the error terms due to interpolation or modification due to the use of fixturing, the channel will generate a temporary "memory-resident" Cal Set. In this case, the active Cal Set is the memory-resident Cal Set. This FLATten command allows you to save the active Cal Set to disk. Depending on the measurement conditions, this flattening of the Cal Set can improve performance, especially if the Cal Set is applied often (using multiple recall states) or used by many channels. Flattening a version of the Cal Set for each channel can avoid the interpolation or the fixturing processing that would otherwise occur when the Cal Set is selected or the instrument state is recalled. You will have to manage the application of such a Cal Set as the VNA itself will have no way to determine what processing had been done once the flatten command is used. For example, if fixture de-embedding occurred prior to the flatten command, that Cal Set should then be applied WITHOUT fixturing on, because fixturing is already embedded in that Cal Set. It is your responsibility to apply the Cal Set properly. If you want to repeatedly de-embed multiple networks (i.e. concatenate multiple 2-port de-embedding files) you can use the flatten command to create a new primary Cal Set after each de-embed, and sequentially add additional de-embed networks.
Parameters
<cnum>	Channel number on which the modified Cal Set resides. If unspecified, value is set to 1
<string>	Name of the new Cal Set. Spaces or punctuation NOT allowed.
Examples	SENS:CORR:CSET:FLAT "MyCalSet"
Query Syntax	Not Applicable
Default	Not Applicable

SENSe<cnum>:CORRection:CSET:GENerate:RECeiver <receiverName>

Applicable Models: E505xA with VNA ports This command converts the selected Cal Set from an S-parameter Cal Set to an S-parameter+Power Cal Set. This command requires a Cal Set to be selected. There are 2 modes for using this command: Mode 1: The <receiverName> is optional. If not specified, then ResponseTracking(a1) is set to 1, and the rest of ResponseTracking() terms are computed to be consistent with the S-parameter calibration terms. Mode 2: Use this pattern when there is already a receiver calibration for one of the receivers. In that case, this command can be used to transfer the receiver calibration to the other receivers. If <receiverName> is specified, it must be either 'a1','a2','a3', etc or 'b1','b2','b3'. The ResponseTracking term for this receiver must already be added to the Cal Set, or else this command will generate an error. This command will then compute the ResponseTracking() terms for all of the other receivers in a manner consistent with the S-parameter calibration terms.
Parameters
<cnum>	Channel number on which the modified Cal Set resides. If unspecified, value is set to 1.
<receiverName>	Name of the receiver ('a1', 'a2', 'a3', etc., or 'b1', 'b2', 'b3', etc.)
Examples	SENS:CORR:CSET:GEN:REC 'a1'

Return Type	String If no Cal Set is applied on the current channel, the following error message is displayed: +163, "Requested Cal Set was not found in Cal Set Storage."
Default	Not Applicable

SENSe<cnum>:CORRection:CSET:ITEM[:DATA]? <itemName>

Applicable Models: E505xA with VNA ports (Read-only) Read the value of the Cal Set item. The Cal Set item is added by the VNA firmware to every Cal Set. About Cal Set Items A Cal Set item is a named value. You can list the named values using CSET:ITEM:CATalog? or SENS:CORR:CSET:ITEM:CATalog? You can query the value of a specific item by asking for its data: CSET:ITEM:DATA? For example, one of the items added by the VNA firmware to every Cal Set is named 'Created By'. The value attached to this item is the name of the VNA Measurement Class or Channel that created the Cal Set. When an SMC cal is performed, you can query the Cal Set for the 'Created By' item, and it will return 'Scalar Mixer/Converter'. The same query on an NFx channel returns 'Noise Figure Converters'.
Parameters
<cnum>	Any existing channel number. If unspecified, value is set to 1
<itemName>	(String) Item added by the VNA firmware to the currently loaded Cal Set.
Examples	SENS:CORR:CSET:ITEM? "Model Number" "N5242B" 'Example returned Model Number value.
