Test 6

Description: This performance test verifies the maximum clock rate for

demultiplexed clocking during state operation.

Specification:

Clock repetition rate: H P 1650B single phase 35 MH z maximum, HP 1651B single

phase 25 MHz. With time or state counting, minimum time between states is 60 ns

(16.7 MHz maximum). Both mixed and demultiplexed clocking use master-slave

clock timing; master clock must follow slave clock by at least 10 ns and precede

the next slave clock by 50 ns.

Equipment:

Pulse Generator ............................... HP 8161A/020

Oscillscope....................................... HP 54502A

50 Ohm Feedthru (2) .............................. HP 10100C

Test Connectors (2)..........................see figure 3-1

Procedure:

1. Connect the HP 1650B/51B and test equipment as in figure 3-25 by

connecting channels 0-7 of the pod under test to the test connector. During

demultiplexed clocking only the lower eight bits of each pod are used.
