Measure Frequency Use [SENSe:]FREQuency:APERture <time>,(@<ch_list>) to configure the frequency counter channels’ measurement interval.
Use [SENSe:]FUNCtion:FREQuency (@<ch_list>) to configure channels to measure signal frequency.
To measure frequency at channel 45 with aperture of 1 second
*RST TRIGGER:TIMER .2 SENS:FUNC:FREQ (@145) SENS:FREQ:APER 1,(@145) ALG:DEF ’ALG1’,’writecvt(I145,45);’
INIT do loop
SENS:DATA:CVT? (@45)
read value from CVT query above end loop
Alg executes at .2 sec intervals ch 45 is frequency counter meas and avg sig periods for 1S alg puts frequency in CVT start algorithm execution
get frequency from CVT
