Hi all, I am starting to dip my toes into time-nuttery after being interested in precise time/position for quite a while (I'm an astronomer IRL). I have acquired a used OCXO and LPRO-101 rubidium, along with a HP5334B (with Option 10) and a HP5370B from ebay and almost done assembling a TADD-2 kit from TAPR.
I recently acquired one of the re-packaged Trimble UCCM GPSDO's (it doesn't seem to be one of the bg7tbl ones) from ebay and have it setup with the supplied puck antenna outside (it's not in a great location (close to the house) but I have set the elevation mask to 20 degrees in the GPSDO) and it's been running for 2 days. The results of the SYST:STAT? command indicate it is in position hold and tracking 3-4+ satellites. Connecting the 10 MHz output to the Channel A input (on the 5334B) or the frequency input (on the 5370B) and setting 50 Ohm termination and AC signals but without any other input or external reference results in a frequency that is off by about 0.1-0.2 Hz. Is this amount of offset expected or a sign something is not right with the GPSDO?
