(Read-Write) Sets the Cal Type for the selected measurement on the specified channel. This is used when a Cal Set is applied. Learn more about applying Cal Types.

• Use SENS:CORR:TYPE:CAT? to list the Cal Types in the VNA.

• Use SENS:CORR:CSET:TYPE:CAT? to list the Cal Types contained in the active Cal Set for the channel.

• Use SENS:CORR:COLL:METH to set the Cal type to perform a new Unguided calibration,

Parameters

<cnum>

Channel number of the measurement (optional).

<mnum>

Measurement number for each measurement.

<string>

(String) Cal type. Case sensitive. Use one of the following:

For Full Calibrations (NO Power Cal included):

This command does not distinguish between TRL and SOLT. The same number of error terms is applied for both Cal Types.

"Full <n> Port(x,y,z...)"

where

<n> = the number of ports to calibrate

x,y,z = the port numbers to calibrate

For example:

"Full 4 Port(1,2,3,4)"

For Full Calibrations (including Power Cal):

After the Full <n> port, include the string, "with power"

For example:

"Full 4 Port with power(1,2,3,4)"

For Response Calibrations:

"Response(param)"  OR

"ResponseAndIsolation(param)"

Where param =  

• S-parameter. For example"

• • "Response(S21)"

  • "ResponseAndIsolation(A/R)"

• Single or ratioed receivers using either logical receiver notation or physical receiver notation. For example:

• • "Response(A)"

  • "ResponseAndIsolation(a3/b4)"

For Enhanced Response Calibrations:

"EnhancedResp(sourcePort, recPort)

Where:

• sourcePort = stimulus port number

• recPort = receiver port number

For FCA Calibrations:

Learn more about this setting.

• "SMC_2P" (Response + Input + Output)  All four sweeps required. Most accurate.

Note: The “SMC_2P” is the only correction type that automatically forces the reverse measurements (SC12, RevOPwr, RevIPwr). If you require any of the reverse measurements while using a lesser correction type, either include those parameters in your channel or use the SENSe:MIXer:REVerse command. Keep in mind that adding the reverse measurements or forcing the reverse sweep using the SENSe:MIXer:REVerse command will increase the number of sweeps required in the channel.

• "SMCRsp+IN"  No Output match. Saves two sweeps.

• "SMCRsp+OUT"  No Output match. Saves one sweep.

• "SMCRsp"  No Input or Output match. Saves two sweeps.

For VMC, multiple Cal types are not available.

For Gain Compression Cal

where r = receive port; s = source port

• "GCA 2P (r,s)”  - full 2-port cal

• “GCA Enh Resp (r,s)”  - Enhanced Response Cal
