Anybody using either 1996 or 1995 racal counters.
I use my hp5061a for external reference to both counters
The racals are continously in mean average mode (10000 seconds).with a different
1pps signals to the racal counters..
Occasionaly the counters present a reading like 10.0 -3 (10ms)
The expected readings should be 0.001 -9 (1ps)
Anybody else using dana racal experience this. It seems like a software bug?
Question number two;
The readings from these racals seem off .
I get a reading like 0.001 -9 equals 1X10 -12 I belive its decimal point mighy be off.
I'm thinking it should be .0001 -9 equaling 1X10-13 When I interpet the readings with the extra digit of accuracy the readings make more sense and correlate with my austorn loran frequency & timing receivers and other counters and gps 1pps signals.
To also support my theory the racal counters will resolve 1X10 -11 using 99 (100s) second gate time. when I activate the mean average mode this extends the gate time two more decimal places (10000 second gate) wouldn't you assume a resultt of 2 more digits in accuracy ?
Don't pick lemons.
