:SENSe:FREQuency:SPAN
Description
This command gets or sets the frequency span of a sweep. If the frequency span is
altered, the start frequency the stop frequency
and the center 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.

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();
visaSession.write(':SENS:FREQ:CENT 10kHz\n')
visaSession.write(':SENS:FREQ:SPAN 5kHz\n')
visaSession.write(':TRIG:SING\n')
visaSession.query('*OPC?\n')
frequencyValues = visaSession.query(':SENS:FREQ:DATA?\n')
measurementValues = visaSession.query(':CALC:DATA:SDAT?\n')
