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 --- End quote --- 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: |

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. Chris |
