:SENSe:FREQuency:CENTer

Description

This command gets or sets the center frequency of a sweep. If the center frequency is altered, the start frequency the frequency span and the stop frequency are changed accordingly.

If the specified parameter is out of the allowable setup range, the minimum value (if the lower limit of the range is not reached) or the maximum value (if the upper limit of the range is exceeded) is set.

Syntax Parameter
:SENSe<ch>:FREQuency:CENTer <numeric>
Parameters accepted format allowed suffixes possible Errors description
<ch> { 1 | empty } none Invalid channel index Currently only one channel is supported. Empty means 1 is used as default.
{ <numeric> | MINimum | MAXimum } Range from Min. frequency to Max. frequency Hz Numeric data error The center frequency value of the sweep

Presets

For presets please refer to Measurement Modes.

Sample usage

Configure and start a sweep measurement with center frequency of 10kHz and a span of 5kHz (from 7.5kHz to 12.5kHz).

var visaSession = new TcpipSocket(VISA_RESOURCENAME);
visaSession.RawIO.Write(":SENS:FREQ:CENT 10kHz\n");
visaSession.RawIO.Write(":SENS:FREQ:SPAN 5kHz\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();
