[time-nuts] Control and monitor program for Spectracom 8195B

[Mark Sims]

I got in an 8195A and managed to get Heather working with the wonky, very much not computer friendly,  Spectracom interface and command set.

When you send a command to the device it echoes back the characters.  This is very useful for telling what command the device is responding to.   But, about half the time, the echoed characters were garbled.   Also several response messages came back corrupted.  Oh, and occasionally the unit would lock up and require a power cycle to recover.   The problem turned out to be that you can't send command strings to the device at computer friendly speeds.  You need several milliseconds of delay between each character you send!

Anyway, Heather now work with the Spectracom "ageless" oscillators.   BTW, for an "ageless" oscillator, these units have a procedure for correcting oscillator aging  ;-)
