This needs to be put in context. The peak of ozone depelting CFC's was in the mid 80's, when R12 was used in all domestic and automotive refrigerators worldwide. In addition, other CFC's were used as

Thanks to all who provided insight on the P6015A HV probe. After due consideration, and considering it's one of the newer type that uses a no-refill-required silicone compound instead of fluorocarbon

If you can use it with a DMM it gives a very high input resistance (probably about a Gigohm?) and with the sensitivity of even basic DMMs will measure 200 volts full scale with resolution down to 0.1

Does anyone out there have a front end channel module for a TDS380 scope??? The schematic shows a AT206/B2565 module. It's a hybrid part. The input channel will measure -5.3vdc on the most sensititive

Tek group I have a transformer pn 120-169 Recollection is that it was changed out of a small scope 30 or so years ago and didn't fix the problem. Don't remember what scope. This transformer is potted

Freon, one of the Ozone layer destroying gasses. There were two of the P6015 series probes, one designed for 25kV and the other designed for 40kV. I say designed because I know from personal

If the talk-only and listen-only switches are both off, and address 0 is reported by the analyzer even though the address switches are set to (say) address 31, then I'd look at the other end of the

Hi ALL, Actually I have several P-6015A HV probes. The older ones came with a can of some Fluorocarbon solution which could be put into the probe allowing for measurement of even higher voltages. I

The ones with the freon fill are P6015s, and the newer ones with the silicone gel fill are P6015As. Without freon, the P6015s are rated to 13kV. Otherwise, the rating is 20kVDC/40kV peak. It's 75MHz,

Hi, Chuck, * REPLY SEPARATOR * <snippage> Thank you. I thought about that after pressing 'send.' ;-) You're right. Other than possibly developing a Tesla coil, as Dave suggested, I

I used one back in the late '70s while developing a small pulsed carbon dioxide laser. Bit of a chewing gum and string affair. This used a high charging voltage (10kV or so IIRC) from an HV power

Fellow tekkies, I was cleaning up today, and came across an item I picked up from Boeing Surplus some years ago: A P6015A high-voltage probe in just about mint condition. I have vague memories of

Hi, I remember now that in the late 90's I'd a similar problem with my 496P. I was using the Tektronix software GRASP and I remember well that I was obliged to leave all the back panel switch to OFF

Hi Thanks for all the helpful suggestions I received earlier but my Tek 494P spectrum analyzer GPIB still does not respond and I could use some help. I took the GPIB board out of the unit (fairly easy

7603 operators and service manuals, excellent condition, almost new. Shipped to your door lower 48 $30 postpaid. Thanks for the BW. Mike W2IY

After spending a lot of time messing around trying to get my 2465 working again without success, I am wondering what my options are. The 2445 works really well & triggers reliably beyond 200MHz. Can

Greetings, ? I just recently got my 7CT1N working with my 7B70 and a 7A26 in my 7603. Yesterday I went to try it out with a new adapter and found that no trace is being generated. The dot can be

If you look at the BAMA and Kurt's different schematics of the 317 PS, the B+/plate supply?winding voltages are different.? The newer diode version is about 10 volts RMS less per winding.? The BAMA

Looks like the draft persons initials and the date. There are different intitals on some of the drawings in the 317 manual. ? Jim

Hello Everyone, I tried posting this yesterday, but it did not show up on the Tekscopes message board... Would anyone know what "R.O.W." in the lower right corner of an older Tektronix schematic
