CALCulate<cnum>:MEASure<mnum>:DEFine <string>

Applicable Models: All

(Write-only) Creates a measurement but does NOT display it, on an existing or new channel. When a new channel is created, any licensed measurement class can be used. Up to 580 (2000 for M98xxA, P50xxA/B and E5080B, E5081A)  measurements can be created.

Note that each display window can only display a limited number of traces. See Traces, Channels, and Windows on the VNA.

This command replaces the following commands:

CALCulate:PARameter[:DEFine]

CALCulate:PARameter[:DEFine]:EXTended

CALCulate:CUSTom:DEFine

Parameters

 

<cnum>

Channel number of the new measurement. If unspecified, value is set to 1.

If the specified channel does not exist, then a channel of the specified type will be created. If no type of channel is specified, then a standard channel will be created.

If the specified channel exists, then the parameter will be added to the channel provided the existing channel supports the parameter (otherwise, an error will be generated).

<mnum>

Measurement number for the new measurement.

If the specified measurement number is already in use, an error will be generated.

<string>

 

(String ) Measurement Parameter and optional measurement class name separated by a ":" (colon). For example, "S21:Gain Compression" creates an S21 measurement and selects the Gain Compression measurement class for the channel.

Note: If a measurement class of a channel does not support the defined measurement parameter, an error is generated.

Case sensitive.

For S-parameters:

Any S-parameter available in the VNA

Single-digit port numbers CAN be separated by "_" (underscore). For example: "S21" or "S2_1"

Double-digit port numbers MUST be separated by underscore. For example: "S10_1"

For ratioed measurements:

Any two VNA physical receivers separated by forward slash '/' followed by comma and source port.

For example: "A/R1, 3"

Learn more about ratioed measurements

See a block diagram showing the receivers in YOUR VNA.

For non-ratioed measurements:

Any VNA physical receiver followed by comma and source port.

For example: "A, 4"

Learn more about unratioed measurements.

See the block diagram showing the receivers in YOUR VNA.

Ratioed and Unratioed measurements can also use logical receiver notation to refer to receivers. This notation makes it easy to refer to receivers with an external test set connected to the VNA. You do not need to know which physical receiver is used for each test port. Learn more.

For ADC measurements:

Any ADC receiver in the VNA followed by a comma, then the source port.

For example: "AI1,2" indicates the Analog Input1 with source port of 2.

Learn more about ADC receiver measurements.
