: I did a quick check of the U.S. Gov't Printing Office
: and found no reference to the AN/URM-127A. I used a
: URM-127 ocassionally (I preferred hp audio generators)
: and saw quite a few since I was in PMEL calibrating the
: things. The U.S. Navy bought a bunch of them, so if
: you can't get help anywhere else, you might try
: contacting a Naval Calibration Lab. Army or Air Force
: cal labs may have one, but I don't know if there were
: any contracts for the URM-127A for them. Anyway, one
: of the cal labs MIGHT (if they're in the right mood and
: feeling really nice) make a copy of one for you, at
: least the schematic, parts list, and calibration
: procedure. Operation of the thing is a no-brainer --
: pretty intuitive since all it has are frequency, range,
: amplitude and attenuator knobs. Sorry I can't help,
: but maybe pointing my finger will help.
My name is Al. I just read the follow up by Dean and believe he gave some great advise. I have several of these units. The ones I have were made by AUL Instruments. Other AUL Instruments equipment I have are as follows:URM-145C RF millivoltmeters,Model
6207-1 RF Generator (800 - 2400MHz),and PF6224 power supply. I need manuals for all or should I say AUL of them! I do have manuals for the SG-1144/U Signal generator,The PP-4606E/G Power supply,and the ME-30F/U Electronic Voltmeter. Can anybody help?
