That's the problem, in the normal mode, the 1, 2 and 5 volt ranges are all off, for example, a 1V signal on the 1V per division scale, displays as if on the 100 mV scale, etc., so I am assuming the

It doesn't impact us at all - we moved over to groups.io lock stock and barrel (including all files and pictures) ages ago. D.

How does Channel 2 work when using the scope in the "normal" mode?  If it seems about right (just not precisely calibrated) when measuring known voltages then the attenuator is switching.

A little history first: Acquired the 'scope recently and everything was working fine. Old battery dated 07-87. Decided to change battery and took all known precautions, but somehow screwed up and

Is that a Good Thing or a Bad Thing???

For audio use, any bnc probe that can handle the voltage will work just fine. Look at the P6007 and P6009. -Chuck Harris Scott Adams via Groups.Io wrote:

Most of my high voltage measurement needs are in the audio frequency range, I like to repair and build vacuum tube stereo amps.

The industry standard probes for portable oscilloscopes are made by Staubli. They are $60-$80US new and are CAT rated for these types of measurements. Allied/Farnell sells some of the models and you

Hi, I am in the middle of a frustrating intermittent problem with a CG5011, and need a right angle extender board for lifting the internal pc boards out of their slots. Anybody have a spare, or know

It's $56 shipping across the US or I would've. Vince. -- K8ZW http://www.metalworkingfun.com http://www.hamradio.fun

At $22 BIN I'm surprised no one in the US has taken a punt just to find out what that plugin does! The thing that puts me off doing precisely that is $104 shipping to the UK!!! Craig

This "lot of 3" item on eBay includes a couple of 5A1xN scope plugins and a "liquid crystal driver"

Good point Raymond. Installing the stab connector at a slight angle to vertical, can wipe the spring right out of the mating connector. Stab connectors are made for only a couple of mating cycles

Thanks.  I'm just getting used to the new ( for me ) spec-an.  Sent from my T-Mobile 4G LTE Device

A while ago, I worked on a 2465B which behaved funnily. Turned out several of these "stab" connectors were missing the tiny spring in the square bushings, resulting in intermittent contact. Raymond

I did my service about a few years ago shortly after machine guy did his....here;s the docs regarding it...I used a non standard Tadiran battery which worked fine....pics

The usual rule of thumb is unless your probes are specifically designed for high voltages, don't subject your probes to any voltage higher than your scope's input rating. So, don't skimp on the
