Note: This command is replaced with CALC:PAR:CAT:EXTended? which lists parameters with "_" instead of "," allowing the list to be parsed easily. This command will continue to work.

(Read-only) Returns the names and parameters of existing measurements for the specified channel.

Note: For Balanced Measurements: CALC:PAR:CAT? may have an unexpected behavior. Learn more.

See Critical Note

Parameters

<cnum>

Channel number of the measurements to be listed. If unspecified, <cnum> is set to 1.

Examples

CALC:PAR:CAT?
calculate2:parameter:catalog?

Return Type

String - "<measurement name>,<parameter>,[<measurement name>,<parameter>...]"

Default

"CH1_S11_1,S11"

(Read-only) Returns the names and parameters of existing measurements for the specified channel.  This command lists receiver parameters with "_" such that R1,1 is reported as R1_1. This makes the returned string a true "comma-delimited" list all the time.

The returned string of this command is easily parsed and used to create measurements using the CALC:PAR:EXT command.

Parameters

<cnum>

Channel number of the measurements to be listed. If unspecified, <cnum> is set to 1.

Examples

CALC:PAR:CAT:EXT?

calculate2:parameter:catalog:extended?

Return Type

String - "<measurement name>,<parameter>,[<measurement name>,<parameter>...]"

Default

"CH1_S11_1,S11"

Note: This command is replaced with CALC:PAR:DEFine:EXTended. This command will continue to work for up to 4-port parameters.

(Write-only)  Creates a measurement but does NOT display it.

There is no limit to the number of measurements that can be created. However, there is a limit to the number of measurements that can be displayed. See Traces, Channels, and Windows on the PNA.

• Use DISP:WIND:STATe to create a window if it doesn't already exist.

• Use DISP:WIND<wnum>:TRAC<tnum>:FEED <Mname> to display the measurement.

For Application Measurements see CALC:CUST:DEF

You must select the measurement (CALC<cnum>:PAR:SEL <mname>) before making additional settings.

See Critical Note

Parameters

<cnum>

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

<Mname>

Name of the measurement. Any non-empty, unique string, enclosed in quotes.

<param>

Parameter to be measured. Quotes are optional.

For S-parameters:

Any S-parameter available in the PNA

For ratioed measurements:

Any two receivers that are available in the PNA. (See the block diagram showing the receivers in YOUR PNA.)

For example: AR1 (this means A/R1)

For non-ratioed measurements:

Any receiver that is available in the PNA. (See the block diagram showing the receivers in YOUR PNA.)

For example: A

For Balanced Measurements:

First create an S-parameter measurement, then change the measurement using CALC:FSIM:BAL commands. See an example.

For Applications see CALC:CUST:DEF.

[port]

Optional argument;

For multi-port reflection S-parameter measurements:  specifies the PNA port which will provide the load for the calibration. This argument is ignored if a transmission S-parameter is specified.

For all non S-parameter measurements: specifies the source port for the measurement.

Examples

CALC4:PAR 'ch4_S33',S33,2 'Defines an S33 measurement with a load on port2 of the analyzer.

calculate2:parameter:define 'ch1_a', a, 1 'unratioed meas

calculate2:parameter:define 'ch1_a', ar1,1 'ratioed meas

Query Syntax

Not Applicable; see Calc:Par:Cat?

Default

Not Applicable

Note: This command replaces CALC:PAR:DEF as it allows the creating of measurements using external multiport testsets.

(Write-only) Creates a measurement but does NOT display it.

There is no limit to the number of measurements that can be created. However, there is a limit to the number of measurements that can be displayed. See Traces, Channels, and Windows on the PNA.

• Use DISP:WIND:STATe to create a window if it doesn't already exist.

• Use DISP:WIND<wnum>:TRAC<tnum>:FEED <Mname> to display the measurement.

Note: For Application Measurements see CALC:CUST:DEF

You must select the measurement using CALC:PAR:SELect before making additional settings.

See Critical Note

Parameters

<cnum>

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

<Mname>

(String) Name of the measurement. Any non-empty, unique string, enclosed in quotes.

<param>

(String ) Measurement Parameter to create. Case sensitive.

For S-parameters:

Any S-parameter available in the PNA

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 PNA 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 PNA.

For non-ratioed measurements:

Any PNA 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 PNA.

With PNA Rev 6.2, 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 PNA. 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 PNA 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.

For Balanced Measurements:

First create an S-parameter measurement, then change the measurement using CALC:FSIM:BAL "define" commands. See an example.

Note: For Application Measurements see CALC:CUST:DEF

Examples

CALC4:PAR:EXT 'ch4_S33', 'S33' 'Defines an S33 measurement

calculate2:parameter:define:extended 'ch1_a', 'b9, 1' 'logical receiver notation for unratioed meas of test port 9 receiver with source port 1.

calculate2:parameter:define:extended 'ch1_a', 'b9/a10,1' 'logical receiver notation for ratioed meas of test port 9 receiver divided by the reference receiver for port 10 using source port 1

CALC:PAR:DEL:ALL

Query Syntax

Not Applicable

Default

Not Applicable

(Read-Write) Sets and returns the selected measurement for the channel using the Tr#. Most CALC: commands require that this, or CALC:PAR:SEL, be sent before a setting change is made to that measurement. Each channel can have one selected measurement.

Parameters

<cnum>

Channel number of the measurement to be selected. If unspecified, <cnum> is set to 1.

<n>

Numeric - Measurement number. These are the same numbers you see in the “Tr1”, “Tr2”  annotation next to the parameter name on the PNA screen.

[fast]

Optional. The PNA display is NOT updated. Therefore, do not use this argument when an operator is using the PNA display. Otherwise, sending this argument results in much faster sweep speeds. There is NO other reason to NOT send this argument.

Examples

CALC:PAR:MNUM 2

calculate2:parameter:mnumber:select 3,fast

Query Syntax

CALCulate<cnum>:PARameter:MNUMber[:SELect]?

There is NO query available to determine if the FAST argument has been set.
