2. Adjust pulse generator for the output in figure 3-19. Pulse generator settings

are different for HP 1650B and HP 1651B.

Setting for HP 8161A:

Parameter Output A Output B

Input Mode Norm ---

Period (PER)

HP 1650B 57 ns ---

HP 1651B 80 ns ---

Width (WID) 20 ns 10 ns

Leading Edge (LEE) 1 ns 1 ns

Trailing Edge (TRE) 1 ns 1 ns

High Level (HIL) 1.9V 1.9V (see Note)

Low Level (LOL) 1.3V 1.3V (see Note)

Delay (DEL)

HP 1650B 18.5 ns ---

HP 1651B 30 ns ---

Double Pulse (DBL)

HP 1650B --- 28.5 ns

HP 1651B --- 40 ns

Output Mode ENABLE ENABLE

Note The voltage levels of the waveforms must have the correct amplitude at the logic

analyzer probe tips. The pulse generator output may have to be increased slightly

to compensate for loading by the logic analyzer.

3. Assign the pod under test to Analyzer 1 in System Configuration as in

previous figure 3-4.

4. In the State Format Specification assign Clock Period < 60 ns, and rising

edge of J clock. Also, assign lower 8 channels of the pod under test to a label

as in previous figure 3-12.

5. Set the State Trace Specification without sequencing levels and set Count

Off as in previous test figure 3-13.
