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

Hello Stan, Thank you for the explanation of what Tektronix did to make the switch from selenium to silicon rectifiers! This all makes perfect sense now that you tell us about the different

I can't think of any reason why bucking transformers would not work just fine. Figuring out how much to buck and obtaining the correct transformers would be the problem for me. Resistors are just

Hi Tom and the rest of you guys, Typically, new selenium rectifiers have a larger internal resistance than new silicon rectifiers and internal selenium rectifier resistance gradually increases with

I have a 7704, which has the delay line vertical plate structure with the + to the final amp transistors supplied through the CRT on nearby pins on the side. Examining the vertical problem, which I

Hi, Sorry but I am not the moderator of that list, I believe the fellow's name is Michael Dunn or something like that. Hello moderator, please remove this account, obviously he cannot do it himself...

My 317 is serial number 184. I have what I believe to be the original manual, although it does not have a serial number written on the inside cover page. I scanned the schematics from the manual, and
