I have a 1345a manual, but am away from my home until Nov. 17th. I vaguely remember that there is a trace rotation potentiometer on the rear panel of the display unit, but I could be mistaken. I'll

I dont have a manual for the 1345 just for the 1349 which is the big brother, A1R160 aligns the trace (rotates) , it is located on the big board that also has the video DACs on there Harke

Hi Jack, I have replaced the strip with wires. For the EHT wire I used the inner of a length of miniature teflon coax. Avoid using too much

Jack, I did it several times in the past. Only one wire (the one most separated from the others) carries about 6kV and must be replaced; remaining wires have voltages in the hundreds of V. I remove

The strip that carries the high voltage to the CRT in my HP 141T has delaminated, and is arcing to the adjacent CRT shield. On a web page, WB8ZDF mentions using super glue to repair the strip, but it

Hi Chris, I have two of the 8657A's and they both power up with the RF enabled (if set that way before power off). Something is wrong with yours. I will try and take a look at the service manual

Dear all, I recently acquired a HP 8756A scalar network analyzer. Now I'm in the process of debugging and learning how to work with it. It seems the display is tilted somewhat as if the crt has been

Hi, I just bought an 8657A generator and I noticed something odd compared with other generators that I have used. When the power is initially turned on, the unit remembers the last setting for

One, and it's in there already, connecting the two boards. I suspect that's the internal trigger and acquisition signals from the sweep to the scope board. Unless I missed one, there are no jumpers

I would think this should not happen. Maybe if it had something to do with the two boards not being connected up correctly. Are there any interconnecting cables between the boards? I don't know

Is there ever a reason for the 16530A/16531A board test to fail a self test in the acquisition memory? I have a "new" board set, which fails self test thusly. I'm seeing a glitch in a fast sine wave

i can get a parts mule locally for next to nothing, one of my former coworkers volunteered one for the cause ! now i just got to find the time and make an excuse to drive to ft worth pdxoregonpete

its one of the advantages of living out in the boonies , you have elbow space and can do whatever you want to, i had a 19x19' slab on my property when i bought it (in fact that was one of the reasons

In the time everyone (myself included) have spent on this thread, the gears could easily have been measured and specified. FWIW, -John pdxoregonpete wrote:

Time yes, but this is engineering :) My offer is still there, if anyone is in Reno to pick it up I'll put10-20 on the bid. If not, next weekend I'll pull apart one of of my two 8640B's, and offer to

When I knew an HP mechanical engineer in the early 80's, the division he worked in either picked gears from another HP instrument, or had them speced, and they were contracted out, his SPC and Boston

Hi again, I found the schematic and the website. Could you fill me in on this site. It looks like a place where anyone? can post their projects. Is it a place where a co-operative design could be

i would probably make about 2 or 3 batches, sure the US market may only hold 4 per year but you have to consider that the 8640 was sold worldwide plus its not really like im running a business where i

I am sorry to post a non HP/Agilent question here. I just want to know if anyone can help me finding the root cause of my 8842A problem. When the meter is powered on, it stuck in rolling reset. The
