SR620 TI setup procedure?
« on: April 05, 2020, 06:57:09 pm »
Minus the data in the manual I've seen a few extra docs floating around but am not sure where to find them now?  Setup procedures for the SR620 for getting best time interval readings.  How do you configure yours?  In frequency I know the SR620 may actually be worse than HP53132A but for time interval it's one of the kings.  This is my Thunderbolt 10MHz feeding into SR620 on Frequency.

I've wanted one of these for while and finally got a nice one with option 1.

That was cold I'm trying it again after warming up for a while... I found this guide from NASA.  I need to feed it external reference next.

Hi notfaded1,

look at PRS10 manual
https://www.thinksrs.com/downloads/pdfs/manuals/PRS10m.pdf
You can find how to set SR620 for "coarse and fine" measurement

Thanks this reminded me where I saw some of this before!  I'm waiting for a new 24V 3A power supply that should come tomorrow for a recently acquired a PRS10.  I have a Ublox LEA-6T on a pcb that can discipline the PRS10 that I was hoping might become my new house standard.  Thanks for the tip!
