2430a service manual

Replace as necessary with heavier duty ones when originals fail. Something like MX-4 compound. Put the compound on the CCD chips with the black heatsinks. The voltage rating of these is higher than the X2 types. Be sure to oil the fan with a heavier oil. That has not been lubricated since it was new. Using a shielded mains cord will help keep noise from being radiated from the cord by the noise coming in and noise generated from the supply. My did this. With a stable repetitive signal you can 'fill in the gaps' with the equivalent time sampling but you still get a somewhat noisy not fuzzy, it is only noise in the Y direction due to the digitising accuracy.

You can smooth the trace by averaging but by this time you will find the scope not very responsive for general 'probing around'. You will find the user interface to be different from an analogue scope in the time that you spend fiddling with menus. On the plus side there are things like the envelope option for recording highest and lowest values that pick out the occasional glitch in an otherwise regular signal and you can mimic a chart recorder for very slow sweep speeds.

I find this very useful for power supplies that switch themselves off just after startup. The FPP errors and recalibration are not a serious issue, anything to do with the CCDs is going to be hard to find replacement parts.

If you want to work on the scope with the case removed you need to supply extra cooling to the CCDs since they rely on the airflow in the duct formed by the PCB and the case. All in all I would say it could be fun at a suitably low price, but don't expect it to be your main everyday scope. I believe the A is the same, but you can check the service manual. I have one of each. My A is one of those. The batteries in the Dallas modules gave up a few years ago so I first lost trace storage and then the calibration data.

No modifications required. I just went through the calibration procedure, which only needs DC voltages, and the scope was good as new, and still is. This cannot be undone. Welcome to EDAboard.

This is a nice scope; I like it a lot. It has several menus. And functions selectable from those menus. I am an electrician and not an electronics guy. I like this scope because the way it is set up makes it easy for a dummy like me to get a usable waveform on a usable display really quickly.

As best as I can tell, everything works. There is a self diagnostic the scope goes through upon start up; it passes that. There are three or four additional menu-selectable diagnostics that you can run. The scope passes all those tests.
