Calculate:Custom Commands

Creates and modifies application measurements.

These commands are Superseded by the CALCulate:MEASure:DEFine and CALCulate:MEASure:PARameter commands.

CALCulate:CUSTom:

CALCulate<cnum>:CUSTom:DEFine <Mname>, <type> [,param]

Applicable Models: All

(Write-only) Creates a custom measurement depending on the configurations and options. The custom measurement is not automatically displayed. You must also do the following:

Use DISP:WIND:STATe to create a window if it doesn't already exist.·
Use DISP:WIND:TRAC:FEED to display the measurement
Select the measurement (CALC:PAR:SEL) before making additional settings.

Parameters

<cnum>

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

<Mname>

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

<type>

(string) - Choose from the following (click or scroll down to view valid <params> for each type)

"Standard"
"Scalar Mixer/Converter"
"Gain Compression"
"Noise Figure Cold Source"

[param]

(variant) Measurement names to create:

Meas Class	Measurement Name	Description
"Standard"	"S11", "S21", and so forth "A_1","A_2", and so forth	S-parameter name Unratioed parameter names with notation: "receiver_source port" See Balanced S-parameter measurement names
"Scalar Mixer/Converter"	For input port X and output port Y: "SCXY" "SCYX" "SXX" "SYY" "Ipwr" "RevIPwr" "Opwr" "RevOPwr"	Learn about SMC parameters Note: Input and output ports are set up using the Mixer Setup dialog. If the ports are not set up using the Mixer Setup dialog, then ports 1 and 2 are the default input and output ports and the only ports that can be used.
"Gain Compression" Learn more	GCA :
	"CompIn21"	Input power at the compression point.
	"CompOut21"	Output power at the compression point.
	"CompGain21"	Gain at the compression point.
	"CompS11"	Input Match at the compression point
	"RefS21"	Linear Gain
	"DeltaGain21"	CompGain21 -Linear Gain
	"S11", "S21", "S12", "S22"	Standard S-parameters; measured at port 1 and port 2
"Noise Figure Cold Source" Learn more	Noise Figure :
	"NF"	Noise figure
	"ENR"	Validate noise source measurements.
	"T-Eff"	Effective noise temperature.
	"DUTRNP" "DUTRNPI"	DUT noise power ratio. (Noise power expressed in Kelvin divided by 290).
	"SYSRNP" "SYSRNPI"	System noise power ratio
	"DUTNPD" "DUTNPDI"	DUT noise power density. (Noise power expressed in dBm/Hz).
	"SYSNPD" "SYSNPDI"	System noise power density.
	"OvrRng" (Opt 029 Only)	Indication that the noise receiver is being over powered.
	"T-Rcvr" (Opt 029 Only)	Temperature reading (in Kelvin) of the noise receiver board.
	"S11", "S21", "S12", "S22"	Standard S-parameters; measured with the port1 and port2 noise switches set for noise mode.
	"A_1","A_2" ...and so forth.	Unratioed parameters; with notation: "receiver, source port"
	"GammaOpt"	Optimum Complex Reflection Coefficient
	"Rn"	Noise Resistance
	"NFMin"	Minimum noise figure that occurs at GammaOpt

CALCulate<cnum>:CUSTom:MODify <param>

Applicable Models: All (Write-only) Changes the selected custom measurement to a different parameter. This is dependent upon the configurations and options. See an example using this command for a VMC and SMC measurement
Parameters
<cnum>	Channel of the custom measurement to be changed. First, select the measurement using CALC:PAR:SEL.
<param>	Parameter to change the custom measurement to. Select a parameter that is valid for the type of measurement. Choose from the same arguments as Calc:Cust:Def.
