vrf DMM 34401A High speed read

Question asked by mstrutt on Jun 17, 2003
To All the high speed capture >500 samples per second is now working
Many Thanks to all that replied Les and Christian

I had a reply from delmar_fryd


AUTOZERO OFF
AUTORANGE OFF (i.e. fixed range to whatever you need)
Aperture 0.02 PLC
MATH Functions OFF
Resolution could be 0.5mV if you use the 10V range (i.e. not too many
digits)
TRIG:COUN 500 (and no trigger delay)
READ? (REAL ARRAY 1D, 500)

this works  a treat

Many Thanks Mike

Yes.  Turning Autozero off will increase the speed of measurement.
Also, set the meter for auto range off and minimum resolution.
Instead of getting one reading at a time, get an array of readings.
Get the array in binary format instead of ASCII.
