So, going through a surplus HP 5087A. All torn down, cleaned and back together. 10Mhz input amp and 10 output amps. Manual talks about setting for 3V rms into 50ohms, all 10 amps appear clean and a little extra time with a spec an gives -55db at 30mhz and < -65 or better for the rest. Dropping to 1V RMS and tweaking the balance pot gives -55 to -60 at 20 and 30, rest in the noise.
All seems good, but what should I be feeding my gear. All of the manuals are pretty sparse on details, mentioning minimum for a few, but no target or max. Will be feeding 3596C 5335A 5370B 8657B 8395/E6380A to start. Maybe I am missing it, but the only mention of level I have seen so far is > -10dbm. The suggested 3v rms in the 5087 manual seems a bit high. Comments, suggestions, guidance? BTW: Name is Chris, HAM since teens, playing with anything technical for longer than I can remember, packet data networking guy for last 18 years by day. Getting around to putting together a decent workbench opposite the HAM station. Never could stand owning/operating things I could not properly service, fixing the issue but first I need to figure out all the gear (and in some cases fix the gear that will be fixing the other gear.). _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
