Re: OT+DC was Re: [TekScopes] 2465 Calibration
0 VDC = A Sin(wt) VAC, where w = 2 x pi x f, for all t, and only when f = 0 which is the type of stuff we often argue about. -- Roy Thistle

To be clearer, if not somewhat pedantic, there are fields everywhere: electromagnetic, gravitational, strong weak. Although general relativity shows light conforms to the curvature of space-time,

7000 plugin socket side covers?
The side covers on the plugin sockets (P/N 200-0950-00) in my "new" scope are in pretty bad condition. I've read where folks have tried 3D printing those several years ago but not sure how that worked

Hi all Roman: I am pretty sure that by removing the trim capacitors, which is easy, you can disassemble and clean all the switches and assemble them again. I will try this as soon as I get some time

Re: 2465 Calibration
Another possible fix is to use AC Termination. This is a Series connected R-C placed in Parallel across the Cable Destination Load. Since you have a fixed frequency (1kHz), and a constant Impedance on

Re: 2465 Calibration
Some responses. Do you have a lot of Overshoot or Undershoot on the waveforms you are supplying it? On the other scope, what is the Rise and Fall Time? If it is too fast, since the Impedance is High,

Tek 2225 Ringing
Hello Everyone, I have a Tek 2225 scope which has an oddity which im trying to fault find. Overall the scope works fine, however, when set to 0.05uS/Div there is a clear ringing on the display. It

Re: 2465 Calibration
That makes sense. Oh, and I discovered that in Cal 02, vertical calibration, the 2465 is NOT put into 50 Ohm DC input mode. It is in high impedance mode. So my voltages are not being divided by 2. So

Re: OT+DC was Re: [TekScopes] 2465 Calibration
It all comes down to resolution of time and level. I have never seen a DC Source (even a battery can be exposed to an Electromagnetic field and vary its amplitude), nor anything to measure it with

Sorry, I forgot to answer the other question. The Voltage on the knob of the PG506 is for a Voltage at 1 MegOhm Destination Termination. It has a note on the front panel that tells you to divide the

Re: 2465 Calibration
Correct. If the Source Impedance (PG506), Destination Impedance (2465), and the Transmission Path (Cable and Connectors), are matched ie. 50 Ohms for all of them, you will have the maximum power

Re: Leo Bodner Fast Rise Pulse Generator for 453 & 547?
Jeff, The pulse rise time at the scope input gets (with such a fast generator) determined by the effective RC at the scope input. Without terminator that will be 1 ns, with terminator 0.5 ns. That
