Table 5-4. Performance Test (Continued)

Setup:

Set the 5328A Function switch to RATlO B/A: Freq Resolution. N switch to 1 kHz, I@: Level A and B to PRESET; AC coupling on both channels; X10 ATTEN on both channels; COM A. Verify that the counter displays 1.000. Mark results on performance test record.

Set the 5328A Function switch to RATlO C/A; SEP. Disconnect the channel B input and reconnect it to channel C. Verify that the counter displays 1.000.

6.TIME INTERVAL AND TIME INTERVAL AVERAGE

Specification:

T.I. A-B - counter measures time intervals (100 ns to 108 see) between a start signal at the channel A input and a stop signal at the channel B input.

T.I. AVG A-B - counter measures time intervals (0.1 ns to 10 see) between a start signal at the channel A input and a stop signal at the channel B input. The number of time intervals over which the time interval average measurement is made can be selected by the FREQ RESOLUTION, N switch.

Description: A 1 MHz signal drives the A and B channel inputs of the 5328A counter.
