Subject: [hp_agilent_equipment] How do you clean buttons on HP uWave gear?? ? I'm FINALLY getting around to hauling the stuff out of boxes - 15 years of storage, ugh.
I have an 8350A sweeper mainframe with 83595A 26.5GHz plug-in.
When turned on, an error message E0004 briefly shows in the mainframe display, then I see the usual display...red LEDs.? In theory, there's a left RPG and right RPG that are setup to establish low and high freq of the sweep.? The left RPG does nothing.? The right RPG seems to have the expected affect.
I'm not sure the RPG is what's wrong, though....
Under the left-most RPG, are buttons labeled START, CW and CF, with yellow LEDS indicating which function is selected.? The START LED is illuminated and that's that..pressing the buttons does nothing.?
In the data entry area with the keyboard, one finds the usual units buttons GHz, MHz, and dBm.? When pressing any one of them, it stays pressed.? Come back an hour later, and it has finally released.
When I worked in Santa Rosa at HP/Agilent in the early 2000s, the official service policy on any of these buttons was "limited lifetime, replace or dispose".? But I have to believe there's a procedure to get them functioning again.
The RF plug-in's buttons are equally defective.
Thanks!
