The Microsemi units—based on John Miles original Timepod—have better performance for much less money.

 

Except that frequency range is from 1MHz up to 400 MHz...😉 (5125a)

Interesting that you include the Audio Precision analyzer in the title of this thread. 

While it is a very nice general purpose unit, it is not well suited to measuring jitter in DACs. What’s that? Heresy!

If you look at the specifications for the ADC in the top-of-the-line APx555, you will see that its own jitter is 600 picoseconds!

So that will swamp the jitter details of a device under test—which might be in the range of 10s of picoseconds. 

 

 

Correct regarding specifications. BTW there are several methods for measuring lower jitter than own equipment, dual ADC + DSP is one of them. 😉
