So that's plus or minus 250Hz at 10MHz /2.5KHz at 100MHz, using a display resolution of 0.001 Hz.

Hi, hope it's not too late for a follow-up question?
Thinking about getting a 1032X or 62X.
After checking endless manuals and videos, I'm still totally confused with what precision output frequency can be entered, say around 1 MHz and 10 MHz.
Seems like only an owner could tell me that :)
(and yes, a GPSDO EXT REF would be used)

Thanks
Paul

Welcome to the forum.

Quick check with 6022X, the only one out, reveals a max of 8 digit resolution and 7 for single digit multipliers.
eg 10 MHz vs 1 MHz.
Therefore 10 000 000 and 1 000 000 provide for 1 Hz frequency steps in the MHz range from inputs via the front panel UI.
SCPI commands may provide for better...need to check.

Nothing special with the frequency counter:





dbnut:
Aha many thanks, TauTech!
Glad I asked, probably should be looking elsewhere for 1 mHz steps.

I'm playing around with my upgraded Siglent 1032x testing an HP5370B.  I have a Rubidium standard on the 5370B and tried bringing that into the 1032x as well.  I see 2V p2p on the reference signal but it doesn't look like the 1032x is recognizing it as the output frequency is still off by 24hz, same as if I disconnect the standard.  I looked around the menus, can't find any way to turn the external frequency reference on.

Ideas?

Jerry

by the way, the reference BNC on the back is labeled In/Out and there isn't a signal on it except for a 16mv, 25Mhz, peak crappy looking square wave.  Looks like there is an issue with the port maybe?

OK, forget all this, I found the setting under "clock". would have named it "reference" myself!  You can turn the output on, etc

Thanks anyway!

Jerry,

please be aware, that the current firmware has a bug, so that the SDG output does not properly lock to the ref input for output frequencies above arround 30MHz.
I have written abourt this in the main thread.

I did not check, if that also causes an issue with the frequency counter.
