Table 5-4. Performance Test (Continued)

l Set the 651B to 1.0 MHz and 500 mV rms.

. Set the 5328A Function switch to T.I. A-B; Freq Resolution, N switch to 1 MHz, 1; Level A and B to PRESET; AC coupling on both channels, X1 ATTEN on both channels, COM A.

l Set the Channel A SLOPE to (+) and the Channel B SLOPE to (–). Verify that the counter displays 0.5 µs ±0.25 µs. Mark results on performance test record.

l Set 5328A Function switch to T.I. AVG A+B and Freq Resolution, N switch to 1 Hz, I(F. Verify that the counter displays 500.XXXX ns. Mark results on performance test record.

l Change Channel A SLOPE to (-) and Channel B SLOPE to (+). Verify that the counter displays 500.XXXX ns. Mark results on performance test record.

7.GATE/MARKER OUT AND SAMPLE RATE Setup:

l Set the 5328A to CHECK, 1 kHz, l@ Resolution.

l Observe the GATE/MARKER OUT signal from the counter. Vary the SAMPLE RATE control to full ccw. The GATE/MARKER OUT signal must be greater than 2.4 Vdc and the sample delay (time during which GATE/MARKER OUT is Low) must be less than 2 msec. Mark results on performance test record.
