Repair HP A Pulse Generator
Front and Rear Panel Assemblies. Not HP’s best design for ease of maintenance.
Rear Panel Voltage Selector and Fuse checked ok. There are 4 outputs from the A3 Repetition Rate Generator and only 2 are working. A3 Repetition Rate Generator. No pulse outputs though.
8082A 250MHz DUAL-OUTPUT PULSE GENERATOR
Up to MHz max Maximum variable delay time: There are 8082 four trigger modes: About Test Equipment Value, Inc. Would you like to receive announcements about auctions and special sales? HP A MHz repetition rate, 2. There may be some intermittancy to watch out for and the External Input slide switch is slightly damaged. Correct contact sliders on the left hand side of the photo. Square wave mode is disabled Synchronous gating – Rate generator starts with a half period delay.
Most of the slider switches were dirty. Your password must be at least 8 characters long and contain at least one uppercase letter. Testing produced the same result though! These rely on specific PCB tracks together with contact sliders that are held by the rivited on plastic runners and retaining springs.
Remind me later Go.
Two separate three step attenuators reduce the outputs to 1 V. A gating signal enables the pulse and trigger outputs External Width Mode: Unable to Process Request Your offer was received but we are unable to process it for the following reason: Additional Info Please provide any additional information which could help us determine whether we can meet your requirements for this offer. Positive, negative, or manual selectable Sensitivity: Surprised that they still work!
Send a Request Hpp Notify me when back in stock. The fault was traced to A3 U2, this is a special HP integrated circuit part number and probably unobtainium!
The A is a MHz dual channel pulse source with variable leading and trailing edge transition times as fast as 1 ns. Welcome to Azur Electronics.
The A has an ECL position on each of its amplitude range switches. The slider switches were all hpp cleaned up and reassembled.
The pulse and trigger output frequencies are determined by the frequency of an externally applied signal. These ICs eliminate the need for fans, reduce power consumption and enable a low reactance 50 ohm source impedance to be used.
Considering all the factors, I decided to scrap this Unit for spare parts. The front extrusion was badly corroded and discarded for a spare unit.
