Oz, So it would depend on what board they would be going in? Thanks, James

Hi Jean-Paul, Ok, then I guess I am puzzled about the whole 2901 thing, as the PG506 can drive most of these pulsers just fine... turn to HV pulse, max pulse amplitude, adjust the pulser's bias

Chuck: Miscommunication: CAL 01 use TG501 CAL 02 Use PG506, ONLY for transient CAL was I reffering to the old 2901! It is used to just drive the TD pulser. Yes I did finally finish CAL 01 and it

First let me state, that in the 10+ years I have been calibrating 2465 scopes, I have never found one that didn't meet its CAL01 calibration without any problems. Never a limit that I couldn't fix by

the power dissipation capability and parasitics are different even if the die is the same. If the application is low power and non-critical, it should be fine.

Dear Chuck, many thanks for these precice diagrams. I found it easier to count the number of pulses per division, as you have mentioned in an earlier post. I did the entire CAL in sequence, PSU,

Getting bit by the anode voltage on a charged CRT feels about the same as a good winter carpet zap to a light switch. It is startling, but hardly harmful for most normal folk. Voltage jumps the gap,

I was only referring to the linemans glove for the high voltage on the 2nd anode when it was removed from the tube. Not to wear. I used to repair TV sets for Heathkit years ago when I was recently out

Hi Jean-Paul, I'm not sure what you mean by "was very long", and iteration has no place in this calibration. Newbies often get confused by tektronix's counts of marker numbers, and graticule lines.

If this helps, I had the same issue when I troubleshot my IFR1500 power supply. With isolation of my DUT and my test meter. So I ended up measuring my voltages in the power supply using a portable DMM

Dear Chuck Mille mercis encore for all your sage advise and experience! I finished the cal of #1, 2467 OPT 06/09 ser B0104xx. I had every cal cable, test fixture and generator. All went fine but a

Walter, Nicely done! Thank you for sharing. George KD6NEW

Nice! Now if I can only find one of these rare plug-ins for my TM506. I like projects like this, even though I probably would not use this too much. Thanks Walter! -- Michael Lynch Dardanelle,

Rule I was taught when I was a young sprog, one hand in the pocket. Most dangerous shock is hand to hand, goes right across the chest, and your heart. But then I started my career on vacuum

If you are not able, unwilling or scared to get an occasional nip while working on scopes or any other electronic equipment with voltages higher than 40-50v probably best to stay away from them in the

Good Lineman's gloves are expensive. Regards

I just added some initial photos showing the before and after of the MR501 converted to a curve tracer. works very well, now I just have to re-do the faceplate. The album is called: MR501/SC501
