Ed, the calculation is the same, however the numbers are 100ps for 53132A versus 350ps, and I have not seen an average systemic offset being displayed on any of the 3x 53132A units I use, and I see one on the SR-620. That's why I sent it into SRS for calibration, paid the $$$ and got it back with the same exact offset and a statement that it is operating within specifications so no adjustment is necessary. HP manages to show zero error on average, with the digits bouncing back and forth. The SRS unit manages to show a hard frequency offset. If I remember correctly the SR-620 even shows this offset with it's own reference connected to the inputs, the HP does not. bye, Said In a message dated 3/17/2013 11:26:16 Pacific Daylight Time, [email protected] writes:
Hi Said, That equation looks similar in form to the specs for any counter. What are the comparable equations for the 53132A or the 5370(A or B)?
