:SENSe:FREQuency:DATA

Description

Gets the measurement frequencies.

Important

You need to perform a measurement first. Otherwise no measurement frequency values are calculated. If you have NOT performed a measurement before calling this command, 0 is returned and a Settings conflict error is added to the Error Event Queue.

Syntax Response possible Errors
:SENSe<ch>:FREQuency:DATA? <numeric>,<numeric>, ..., <numeric> Settings conflict
Parameters accepted format description
<ch> { 1 | empty } Currently only one channel is supported. Empty means 1 is used as default.
Response value description
<numeric>,<numeric>, ... <numeric> list of measurement frequencies separated by a , (the amount of elements is equal to the number of points set by :SENSe:SWEep:POINts)
0 No frequency data available because no measurement has been performed. Additionally a settings conflict error has been added to the Error Event Queue.

Sample usage

Configure and start a S21 measurement.

var visaSession = new TcpipSocket(VISA_RESOURCENAME);
visaSession.RawIO.Write(":SENS:FREQ:STAR 5kHz;STOP 50kHz\n");
visaSession.RawIO.Write(":CALC:PAR:DEF S21\n");
visaSession.RawIO.Write(":TRIG:SING\n");
// wait for the measurement to finish
visaSession.RawIO.Write("*OPC?\n");
visaSession.RawIO.ReadString();
visaSession.RawIO.Write(":SENS:FREQ:DATA?\n");
var frequencyValues = visaSession.RawIO.ReadString();
visaSession.RawIO.Write(":CALC:DATA:SDAT?\n");
var measurementValues = visaSession.RawIO.ReadString();
