Hi, I can load the strobe and it seems to load correctly since I can do fetch and confirm that what I've loaded is present but when I replay the word sequence there's nothing on the strobe BNC, the data channels output waveform just fine but the strobe BNC is stuck at H all the time. I wonder if I have a defective unit which is quite possible. I did try RZ and NRZ on the strobe BNC and the result is consistent with no waveform being output.
I did want to confirm the strobe loading sequence nonetheless with someone who has worked the 8016A before. I figured that when loading strobe one can pick multiple word locations, same applies when fetching the strobe -- the location LEDs where strobe is loaded, and by "loaded" I presume the strobe bit is set to 1 for those locations, so those location do light up when I press fetch. Still the BNC doesn't output anything so I just wanted to make sure this is the correct loading sequence before suspecting that the whole strobe circuitry maybe dead
