What do you do when you get a call from AUSTRALIA
Yesterday was a really nice day. The temperature was perfect, the sun was out. I was on the deck of our little summer house working on my computer. In front of me across an inlet of Puget Sound I can

7603 Graticule Intensity Off Switch: S102
Hi Eric et al, Strange! I have three 7603s and NONE of them have a detent at the full CCW position. They just stop rotating at that point. Thanks for explaining to me that the switch allows the scope

7603 Graticule Intensity Off Switch: S102
Mystery solved. I found out where it is and how it works. The switch is on the end of the dual pot. It does not have a "detent" or mechanism to provide tactile feedback when the switch shuts off the r

P6302 / AM503B 330MHz Oscillation Where is this from?
Hi Albert, First: what is HAPG? Second: that was an excellent suggestion to try feeding it a signal from a SG503 to see how it behaves with higher frequency signals. The SG503 only goes up to 250MHz.

Updated album Mystery 330MHz signal on top of a 3mA pulse from a P6302 - AM503B Combination
#photo-notice
Hi Ed, Thanks for the suggestions. I haven't tried it with slower pulses of square waves. That might give me a clue to the origin of this signal. When I get a chance I will give this a try. "Ringing"

OUTSTANDING NOTES! Topic Was: Persuading a 7S12 to play nice with a 7934.
Hi Richard, WOW!!! YOUR NOTES ARE ASTOUNDING! https://groups.io/g/TekScopes/files/7S12%20in%207934/7S12%20in%207934%20v2.pdf I have never seen anything that even comes close to the notes you placed in

Has anyone replaced the Graticule lights with LEDs?
Hi Jean-Paul, I understand the physics of the incandescent bulb Tek uses. I have many spares of all of the incandescent Tek put into their scopes, plugins, TM500 instruments etc. So I have no problem

A6302 Current probe analysis and modification
Hi Twig, This is not breaking protocol at all. This is exactly the opposite. It is extremely good timing for me since I just posted several P6302 questions I had and one of them is about the same sort
