Hello
I know how to measure ADEV with frequency method (using a 53131A counter) or
time difference method (using 1 PPS of a GPSDO for example) but I would like to
measure ADEV in the sub-second domain (from 0.1s to 1s for example). Do I need
a Time Interval Analyzer, if so, an HP 5371A is ok
Hi
The cheap / simple approach for ADEV is a single or dual mixer setup. Mix the
signal(s) down to an audio frequency and measure those. Mix down
frequencies like 10 KHz will let you measure some pretty short Tau’s.
If you want a purchased single box solution, then something like a TimePod
Claude
what is the simplest method to measure sub second ADEV?
The answer depends on many unstated things.
Among them is your definition of simple, the Frequency of the DUT, the noise
floor, your budget and your available time..
After budget and frequency, the next most important thing is the
