If you're doing anything with baseband video, such as CCTV cameras for surveillance systems, video tape recorders, etc., then you'll want this. It looks at very specific things on the video

You seem to say that it too sometimes displays the same behaviour, which is only natural, as may be deduced from what I wrote earlier. You are looking at a very slow ramp/edge, triggering a time base

The 1480 series are excellent video waveform monitors but not useful as general purpose scopes. Of limited use now, even as waveform monitors since they only do standard definition analogue video,

I have been given this tool. I have a Tek 2246A and a Hitachi scope already. What can I do with this that I can't with the other scopes? I have never done anything with video nor intend to. Also, the

Yes, of the four fastest speeds, 50ns/div is always jittery +/- 1/2 div. 20 ns is usually solid, with maybe 1/2 trace width jitter. 100ns/div and 200ns/div randomly can have excess jitter. These show

It does indeed. No assembly error. You would have noticed or would notice soon if incorrectly mounted... Raymond

@Raymond Thanks for the reply and for sending the TDS600B software, much appreciated. @Zenith I have sent a PM to you offlist - thanks again for the reply.

I doubt that the B-model software will work on a C-model. Reply to me off list and I'll mail it to you. /H?kan

Problem fixed. I replaced that suspect capacitor with a 4.7uF, 100V electrolytic, and now the delay time after which the B sweep starts is rock stable... Now I have a suspect, which maybe somebody

With "not at other speeds" you mean not at faster speeds either? Use enough brightness to judge that, since the jitter may not be evenly spread. Related to what I said before about trigger level: Do

from Tim P (UK) I wonder if those stand-off bushes used to space pots off front panels (particularly 500-series plug-ins) would suffice. Tim

Or, in a pinch get a short tube, rubber, silicone, a striped off? jacket? from cable, heat shrink etc that fits over snugly? on the? pots threads. Then just add some cleaner drops in the tube or

I think GC Electronics made them for their contact cleaner. Long cylinder that threaded onto the mounting nut, maybe 5 inches long and necked down to a small diameter that fit the aerosol nozzle of

No, this is a symptom I am asking for help with. The jitter is constant at all trigger levels on 50ns/div, but not other speeds.

I found them on ebay, I might get a set for my restorations. https://www.ebay.com/sch/i.html?_nkw=guitar+pot+cleaning+cap Thanks for the heads up! :)

Oh yes, it is absolutely normal. The slope should be much steeper for measuring pulse widths or slopes: Consider the fact that with your setup a minimal difference in trigger voltage means a

To me, that would make sense if the wire went through to a contact inside the socket. The sockets I have are sealed at the bottom. If they did it that way, then it makes sense. Not su

George- I have been thinking of where the wire may have originated, I looked at my 6202A and realized it might be the "feed through" wire to the replaceable tip. If that is the case then the (working
