Re: [time-nuts] Hp5061 Cesium Zeeman adjustment

Thanks Corby. Well didn't find the zeeman peaks but using a GPSDO it was very apparent what the peaks are. Its now set and the real issue is that the base unit was a option 004 now with a standard tube in it. Changing the C field resistor moved it into the correct offset range. 300 ohms down to

Re: [time-nuts] My TICC came in the mail yesterday

FWIW, here is a quick test I ran on my TICC, assuming the attachment makes it. "TICC base" was a Trimble Thunderbolt reference and PPS. The reference for the other traces was an FE-5680A with an LTE Lite on ChA and Trimble PPS on ChB. The GPS antennas are indoors and entirely sub-optimal. The

Paul, The Zeeman frequency you use depends on what synthesizer frequency your unit is set for. Either 48.82Khz or 53.53Khz. See: https://www.febo.com/pipermail/time-nuts/2008-July/032378.html The Zeeman coil is close to a short. You set the amplitude to the spot that gives you the best look at

Working on a 5061 that I can actually see the beam current on. Looking at the manual it says to inject a frequency and there are several possible in the 50 KHz range. But it never says the drive level of the signal to use. Since this was fairly vintage equipment I might assume the coil was driven
