Neville, Thanks for the reply. I forgot to give the details of the computer. I am using an old Dell running Win2000 Pro that has two serial ports and allows me to monitor the 3816A and the TBolt at the same time. As I said, the other TBolt works fine when connected the same way. I still think

I have acquired a nice 10 MHz oscillator, but have absolutely no data. Model is marked as a McCoy OSC92-100B, it is rectangular 3x2x1.5 with six leads out one side. Does anyone have the pinout, operating voltage, EFC voltage for this unit? Thanks in advance, as always. Regards, Skip

Hi! I'm logging data from an HP 5335a (using it as a time interval counter). and from a Motorola gps board ( text data). The test setup is comparing the 1pps output from the gps board to a divided (Thank you Dave Partridge!!) down 10 MHz from a Trimble Thunderbolt. The text data is used to

Since the birthday when I was given my first digital watch, I've been concerned about having my watches and clocks set to the correct time, right down to the second. In the 1980s I was able to determine the time using WWV on a shortwave radio. Later, I was thrilled to see radio controlled clocks
