Greetings. I work in the audio industry and had my teen years in the back yard of Tektronix , so naturally gravitated to using Tek gear. I am not a collector, just a user,... I use my Tek stuff in a

Guess I should have remembered to look there first... As a last resort, you may need to look at the schematics from some other signal generators of that era and look for the same looking pin-out

One of these turned up and I wonder what the 104F mod is. Anyone? https://www.ecosensory.com/tek/556-scope-serial-numbers-3.jpg

--- Hi Roger, You may be seeing semiconductor junctions turning on. Does switching polarity of the ohm-meter leads change the measurement? Does changing the range of the ohm-meter change the

Dear all, Before measuring the signals with the scope as Ozan suggested, I decided to check for continuity and shorts with the unity off. The resistance of all pins of U350, U305, U360 and U380 to

You can find the manuals here, I haven't found any more info that what is in this link: https://w140.com/tekwiki/wiki/AFG5101

Do you have a pdf of the manual you could put in the files section? Thanks -- T. Gerbic Central California

Hi,? Still searching for the information on this option board if anyone has one?? Thanks!

Perhaps a systematic review might help. The theory is that the signal progresses from generator to output without distortion (read, flat topping). So starting from the generator, identify the stage

--- Hi Roger, There are only few components around U350B so this is a real puzzle. I suggest we keep the scope at 1V/div, DC-coupled, and set trace on X axis when input is grounded. This way we can

I have 4 465 part scopes I need to get rid of. One is complete, one is 99% complete, the other two are missing various bits. All guaranteed not to work. These came out of a firm that did CNC repair.

Dear all, I came back and checked the signal as suggested. The signal at the Emitter of Q310 is correct. However I get the same "plateu" of the staircase signal at pin 7 of U350B. I have added a photo

I'll check that out some time. I did note that some other elements of the CAL 06 instructions were less than ideally written; for example where you need to repeat tests for CH2 after doing CH1 it

Hi all, My 7L13 Spectrum Analyzer is back up and running but has some instability and other idiosyncrasies. After having a Tantalum fail recently, it is time to replace as many of the Tantalums as

Most of my customers were interested in the "B" scopes, so I never did enough 2465A/2467's to remember much about them. I did do a lot of 2465's, though. I took a quick look at the 2467B instructions

I have just done the CAL 06 in full using PG506 without TD pulser and using a HP 8657B in place of a secondary levelled generator. I've used a switchable 90dB 2GHz 1 dB step attenuator in place of the

Lee, You are Correct.? The outer knob comes off the shaft first by releasing the set screw.? The larger dial control bezel mechanism and pot remain, held in place by the spanner nut, ? The spanner

Thanks for the reply. I don't think it's correct, though. After removing the inner knob, I can see a screw on washer with two slots in it that secures the outer knob and the pot shaft together.? I
