What Additional Measurements Must I Make - HP 1652B Getting Started Manual

Since the data stored in memory is correct, it's time to look at the
hardware to see if it's causing problems during the initialization
routine. You decide to look at the activity on the enable lines during
this routine.
In order to see time domain measurements on hardware signals, you
need the timing analyzer.
What
Since the problem exists during the routine that starts at address 0550,
Additional
you decide to look at the timing waveforms on the enable lines when

the routine is running.
Must I Make?
Your measurement, then, requires verification of:
0
actual response of enable lines from the five ports.
0
correct timing of the responding enable lines.
