CALCulate<ch>:MEASure<mnum>:GCData:DATA? <param>

Applicable Models: N522xB, N524xB, M9485A (Read-Only) Returns measurement data at all frequency and power data points for GCA SMART sweeps and 2D sweeps. When using SMART sweep, ALL data is returned including ALL background iteration sweeps. Use CALC:MEAS:GCD:ITER to determine the number of iteration sweeps. The number of data points that are returned is always going to be number of frequency points times the number of iteration sweeps. When using 2D sweeps, ALL data is returned. The number of data points returned / freq may vary. Learn more. Use CALC:MEAS:DATA? to return just the displayed data results (not the background sweeps). A compression parameter must be present. Learn more. The format of the data is the same as the format of the measurement that you select using CALC:MEAS:PAR. If the measurement is scalar, than one number is returned per sweep per data point. If complex (such as Smith Chart format) than both real and imaginary numbers are returned. If correction is on, corrected data are returned. Otherwise, raw data are returned.
Parameters
<ch>	Any existing channel number. There must be a selected measurement on that channel. If unspecified, value is set to 1
<mnum>	Measurement number for each measurement. There must be a selected measurement on the trace. If unspecified, <mnum> is set to 1.
<param>	(String) Parameter to read. NOT Case-sensitive. The specified parameter need NOT be displayed or selected. However, a compression parameter must be present. Learn more. Choose from: "pin" - (CompIn21) Input power at the compression point. "pout" - (CompOut21) Output power at the compression point. "gain" - (CompGain21) Device gain (S21) at the compression point. "inputmatch" - (CompS11) Input match at the compression point. "DeltaGain" - (DeltaGain21) Measured Gain (watts) / Ref Gain (watts). Learn more. "AI1" and "AI2" - ADC measurements at the specified compression level. Learn more. Learn more about GCA parameters.
Examples	data = CALC:MEAS2:GCD:DATA? "pin" data = calculate:measure2:gcdata:data? "pout"
Return Type	Array of data
Default	Not Applicable

CALCulate<ch>:MEASure<mnum>:GCData:IMAG? <char>, <dpoint>, <param>

Applicable Models: N522xB, N524xB, M9485A (Read-Only) For a specified data point, returns the imaginary part of the specified Gain Compression data. If correction is on, corrected data are returned. Otherwise, raw data are returned. Can be used with Smart and 2D sweeps. For SMART sweep, the number of data points that are returned is always going to be the number of iteration sweeps. Use CALC:MEAS:GCD:ITER to determine the number of iteration sweeps. For 2D sweeps, the number of data points returned / freq may vary. Learn more.
Parameters
<ch>	Any existing channel number. There must be a selected measurement on that channel. If unspecified, value is set to 1
<mnum>	Measurement number for each measurement. There must be a selected measurement on the trace. If unspecified, <mnum> is set to 1.
<char>	Choose from: FREQuency - for the specified frequency data point, returns all of the measured data for each power stimulus. POWer - for the specified power data point, returns all of the measured data for each frequency stimulus.
<dPoint>	Data point (FREQ or POWer) for which data is returned.
<param>	(String) Parameter to read. NOT Case-sensitive. The specified parameter need NOT be displayed. However, a compression parameter must be present. Learn more. "pin" - (CompIn21) Input power at the compression point. "pout" - (CompOut21) Output power at the compression point. "gain" - (CompGain21) Device gain (S21) at the compression point. "inputmatch" - (CompS11) Input match at the compression point. "DeltaGain" - (DeltaGain21) Measured Gain (watts) / Ref Gain (watts). Learn more.

Examples	For the fifth frequency data point, returns 'Power Output' imaginary (phase) data from all power stimulus values. For SmartSweep, if there are 30 power sweep points, 30 values are returned. For 2D sweeps, 30 or 31 power sweep points may be returned. Learn more. data = CALC:MEAS2:GCD:IMAG? FREQ,5,"pout"

CALCulate<cnum>:MEASure<mnum>:GCData:ITERations?

Applicable Models: N522xB, N524xB, M9485A (Read-only) In a SMART sweep, returns the max number of iterations that it took for ALL frequencies to converge. Use this number to determine the size of the block data that is returned from Gain Compression SMART sweep data queries. For a 2D sweep, returns the number of power points.
Parameters
<cnum>	Channel number of the measurement. There must be a selected measurement on that channel. If unspecified, <cnum> is set to 1.
<mnum>	Measurement number for each measurement. There must be a selected measurement on the trace. If unspecified, <mnum> is set to 1.
