Agilent Technologies 54622D Measure the following, To verify horizontal Dt and 1/Dt accuracy

Testing Performance

To verify horizontal Dt and 1/Dt accuracy

4Change the calibrator to 1-∝s markers. Change the time base to 200 ns/div. Adjust the trigger level to obtain a stable display.

5Measure the following:

Frequency 1 MHz — The test limits are 997.9 kHz to 1.002 MHz.

Period 1 ∝s — The test limits are 997.9 ns to 1.002 ∝s.

If the measurements are not within the test limits, see the “Troubleshooting” chapter. Then return here.

54622A/22D/24A only

6Change the calibrator to 10-ns markers. Change the time base to 5 ns/div. Adjust the trigger level to obtain a stable display.

7Measure the following:

Frequency 100 MHz — The test limits are 99.10 MHz to 100.9 MHz.

Period 10 ns — The test limits are 9.91 ns to 10.09 ns.

If the measurements are not within the test limits, see the “Troubleshooting” chapter. Then return here.

54621A and 54621D only

8Change the calibrator to 20 ns markers. Change the time base to 5 ns/div. Adjust the trigger level to obtain a stable display.

9Measure the following:

Frequency 50 MHz — The test limits are 49.77 MHz to 50.23 MHz.

Period 20 ns — The test limits are 19.91 ns to 20.09 ns.

If the measurements are not within the test limits, see the “Troubleshooting” chapter. Then return here.
