Russell, Load TBoltMon on your computer, connect the TBolt to the Serial Port, connect the antenna, connect the power supply (make sure of the correct connections), fire up your computer, then turn on the TBolt, double click the TBoltMon icon, select the appropriate port, and just watch what happens. If you have a power supply that monitors voltage and current, the +12VDC will go > 550 mA for about 5 minutes then settle around 130 mA after the oven stabilizes, the +5VDC will be around 250 mA, and the -12VDC will be extremely low, maybe 5 mA.
Should not take too long (30 to 45 minutes for a first acquisition) before all indicators are 'in the green' as shown on TBoltMon. Since you apparently do not have another 'standard', you'll just have to trust that the output frequency is correct, assuming all is 'in the green'. Caution, this can be addicting.

This is my first attempt at having a time reference for my home lab. I have recently ordered a pulled / untested Tbolt (board in box wo/ power supply) from ebay. It has a 5 day right to return if non functional. While waiting to receive the unit, I have been getting things ready here (antenna, power supplies w/ connector, and TboltMon). My question..... Is there a check out procedure or list of things that I can test quickly to determine if I have received a functional unit with a decent oscillator? I just want to make sure I have not been sent a dud. Longer term I can read more, learn, monitor and tweak its performance. I am only trying to make sure I have a good platform to start with. Thanks for you advice / comments. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
