If both sources drift less than 100ns max (pk to pk) at 10MHz, then their 10MHz outputs can be used directly to start/stop the 5370B. Choose a cable length, and a rise/fall trigger so as to measure as close to 50ns as possible, so the signals can drift up or down from that 50ns average. The advantage is getting many (up to 20 samples per second or more) rather than just 1 sample per second. bye, Said In a message dated 12/29/2009 11:04:49 Pacific Standard Time, [email protected] writes:
For most caesium standards and for some GPSDOs the jitter of the PPS output exceeds the jitter of the 5370B so using the PPS output to arm the 5370B reduces the measurement noise over the setup where the PPS output is used to start (or stop) the 5370B.
