To all interested, the images made by Pentti (downloaded from Bruce)are ver. -02. Maybe the name of the archive file can be modified accordingly? Best regards, Bogdan

except *except* I went for a Fluke 80K-40, which is 1000:1 and an input resistance of 1G-ohm. Goes to 40kV, so amply good enough for final acceleration voltages. Craig

I just have a Fluke 40K-6 6 kilovolt probe which is good for anything except the CRT acceleration voltage. It is very accurate on all of my meters *except* for my best one, an HP 3478A, because that

Aren't these voltages mostly DC? Wouldn't a good old DC HV probe do the trick as well? No CFCs. I got an old RCA HV probe, and once I replaced the shunt resistor with a home-made (filed down)

Hi, Sounds like Hybrid battery work. There are several nice 475s on ebay. Just search for tektronix 475. If you like, I have a 3 channel 7704A on ebay. See item 290839243077. It should serve well and

Hi, several things: as Tom Jobe suggested, you can do the following: with the scope disconnected from the mains, check the resistances between ground and each supply. As Tek says, use an ohmeter that

I would recommend a P6015 or P6015A. That's what I've used for decades. A P6013A would do it as well in most cases where the voltage is not above it's max rating.

There is a pdf scanned manual for the later 608E/F on the Agilent manual archive site' if that's any help...the direct url is: -

Hi, I am offering some modules and boards I no longer want. I have described them as best I know. The actual shipping cost will be added to each. At these prices, no refund or return is offered.

Thanks Francis, that's also the answer to my 2232 question where the resistors are 33 Ohm / 0.2 W. Waveforms 65 and 66 in the 2232 manual leave about 4 V for Vce during conduction. Albert

Look for a 475. 250 MHz BW and usually under $200. Less if you care to learn how to repair the known issues (capacitors). This is an excellent general purpose scope. Regards, Tom

In my lab (aka basement), the "noise" is mostly RFI pickup. Did you try connecting a termination to the 7A26?

Sorry, this is long. Maybe you folks can help with our project, point us to sources of RF help, or at least help me find a scope. But because this is a scope forum I'll start with the scope part. I

Hi Priya, I think all that the 'chirp mode' is telling you, is that the voltage drop across R2201 is too high, which fits right in with the over current damage you have already repaired. With the

What High voltage probe/s do you recommend to work on Oscilloscopes? The older scopes seem to have much higher voltages. The 7603 has 12KV and -2975V. Newer scopes have only 2KV :( Thank you Daniel

That is the terminology used for servers which consist of a rack into which one can plug different types of server blades, for instance

Sounds like ABS -- it has some flex and does not shatter easily, (maybe if in Alaska winter).

Thanksfor all of your input. I redid the cal 2 and 3. Vertical and triggers. Error is still there. Looks like at low frequencies-below .5 MHZ it works, above that the error occurs. I am thinking there

Thanks! There is no fundamental connection between amplifier input impedance and noise. I've design preamplifiers with sub-300 pV/rtHz, and they could easily have GOhm input resistance. That's because
