Ray, Bonjour No idea about the divider, the output must drive a 50 ohm load, at leas 1 V Easier with discrete parts. No freq divider needed. Usually a 1-10 MHz rate. many fast pulser designs on

Status update on the 485; as I mentioned in the earlier post, ALL the voltage rails were very close. I¡¯ll list them this time as I was asked if I checked them. Here they are; +- 15v, +-5v, +-5.5v,

First look up the 570/575 manuals and catalog info and see if P11 was ever even an option for these. I think all the curve tracers used low speed CRTs, so it's possible there was never such a thing in

Raymond no replys seen in your last msg. Forgot that latest Leo Bodnar site update no longer lists the BNC pulser version, Their new pulsers are SMA connectors, with SMA to BNC adapter Jon

Hello again Raymond, A few notes on the CAL and fast rise pulses. 1/ Tek service manual CAL procedure is vague in a few places, see the notes from Chuck Harris on tekscopes2. 2/ since 1980s, we

Michael, Resistors: R1853, R1854, R1871, R1872 and R1880 are stressed. It is advised to make them 1W 1%. when these go bad, the focus will be off or not at all. R1991 is advised to replace with a 1%

To find the "where used" info, you need to refer to the RPR microfiche.

Congratulations! I meant High Drive Focus when I wrote (high intensity) focus. Raymond

When we closed our Electronics shop at the University, I bought a pallet full of stuff. In that, there was a small parts cabinet with drawers of components. About half appear to be Tektronix, many

The 2465B should keep focus when you turn up the intensity (at least you shouldn't need to change focus from low intensity to high intensity). Quote from the manual: "Focus tracking for intensity
