 Hi Bob,
 
 Thanks for the suggestions.  I am using a Quadtech SS-100 direct
 USB-Serial cable with Prolific drivers as a direct connect from TBolt
 to PC.  Maybe I should try a direct serial to serial without the USB
>> adapter.
 If still an issue then I will reflow the DB9 connector in the TBolt.

 Hi
 
 I would blame the usual “coms error” stuff and dig into that. Bum
 cable / loose cable is number one on that list. Connectors (on either
 end) coming unsoldered from the pc board would be next ….

[time-nuts] Using Timewave

[Jerry Stern]

I have a PM6690 and it seems to work with Prologix GPIB/USB and latest version 
of Timewave.  I have never used the software before.  I have my Thunderbolt 
connected as external ref and as Input A measuring Freq.  inset up Timewave for 
a modified Allan Dev taking datapoints every second for 2 hours.  After about 
10-15 mins it had collected 7200 points and stop and said insufficient data 
points were acquired.  Why did Timewave stop exactly at 7200 ?

Any advice appreciated to get me on the right track
