I have a pair of DM501As that I use as my every day go-to DMMs on my bench. They work well. I have noticed, though, that with an open input on the 200mV range, one reads about +11mV, and the other

Hi David, Did you ever resolve this issue? I'm observing something similar, though I can't see any signal in DC or AC coupling. I'm trying to determine if the AM503B or A6302 is at fault (or both).

I had never seen this unit until I “googled” it, however if you google this phrase “ Scientific Atlanta 4647 IF noise tester document” I found ATE Corp.,they rented this unit to customers,

We used TEK PG506 and,TM501. The Leo Bodnar 40 ps pulser is only ?49 and very useful. Perhaps someone nearby has the TEK,CAL plug-ins ? Jon

The traces are no signal, input open-circuit, with attenuator x1 and 1mV/div, i.e. worst case. I was just showing how much the transformer’s magnetic field affected the plugin. “Transformer power

Thanks to everyone who responded, both in this thread and privately. I am now suffering from the paradox of choice, which is fine: it gives me good subjects for research while I sock away money for

Dave, I've been looking at the pictures in the album you created ("Type W Plugin 8416-to-6DJ8 Conversion" here /g/TekScopes/album?id=261883) and I'm wondering about the three pictures

I'm located in a suburb of the Minneapolis/St. Paul area of Minnesota.

The fast edge low-aberration. This means a 1ns or better edge with good settling at the transition, no ringing or other issues this is usually a cal source or a tunnel diode pulser to speed up the

Square wave, 0.5 VPP, from ground to +0.5 volts at 1 kHz. Where are you located? Maybe someone close has the cal generator. Regards, Tom in MD? WA3PZI

I'm trying to calibrate my 2465 but don't have the Tektronix calibration equipment. For the CAL 01 Horizontal adjustments, I used square waves from my Hantek oscilloscope/multimeter/waveform

With the low side being way below expected I would suspect the capacitor it seems like the entire frequency range is shifted. On thing to not in tuning the 503 is some of the ranges are not tuned for

I haven't been able to get this HT operating so I'll have to wait until the budget allows for some kind of receiver. Please don't give up on me, but it may be a minute before I can continue this

Here you go: https://elektrotanya.com/philips_pm3262_service_manual.pdf/download.html#dl There are multiple websites that have the manual. Just google Philips PM 3262 . Hope this helps, Gordon

Well i had a brief look to remove the psu pcb,looks a pig to get at,im off to hospital tomorow so will have a deeper look into it after that,i like the fact it has dual timebases,only paid just under

you should already have the WOW64 emulator. install the (your) program and go Renée

here the service manual , I must say these scopes are good , but often used poor quality caps ment for low end equipments? , very good CRT's and good EHT , here the link to the manual
