Dear All,

I have a GPS freq standard(910R) and HP5351B/HP53132A counters in my lab.

When performing frequency measurements of frequencies , i tie the time bases of both the standards and the counters together depending on the range of freq that i want to measure.

My question would be how could i ascertain the measurement uncertainty if i perform the above action?

Should i RSS the errors contributed by my GPS Fre Standard and the systematic Uncertainty given in the manuals of the counters?

if so, what are the values of the GPS Freq standard that i should consider?

Appreciate the help ...

I have attached a spreadsheet that calculates systematic uncertainty for the 53132A. (You will have to enter in the Gate time and frequency that you are using)

Then, you just need to substitute your time base error (instead of ours), into the spreadsheet, and your timebase accuracy in seconds(tacc).
