Systematic Uncertainty: ±(Time Base Error × TI) ± Trigger Level Timing Error ± 1.5 ns Differential Channel Error (Agilent 53131A)
± 900 ps Differential Channel Error (Agilent 53132A)
Time Interval Delay
After a Time Interval Measurement has begun by satisfying the trigger conditions on Channel 1, the instrument will wait for the
user-entered delay time to elapse before the end-of-measurement trigger will be accepted on Channel 2. Please refer to Measurement
Arming for additional information.
Frequency Ratio:
Measurement is specified over the full signal range of each input.
Results Range: 10

‘Auto’ Gate Time: 100 ms (or sufficient cycles on Channel 2 or 3 to make a valid measurement, whichever is longer)
LSD:
RMS Resolution:
To minimize relative phase measurement error, connect the higher frequency signal to Channel 1 when possible.
