Hi Rich,
i made a shot of "D10" with an DS1052E. The edge seems nice enough to me, couldn't catch a glitch either. If there would be that much glitches to trigger the RTB repeatable and only on the supposedly "wrong" edge i would expect the DS1052 to catch them. It does it also not only for "D10", its the same with "CH1". Every 3s or so the scope seems to get unshure where to trigger and toggles between both edges. The 500us/div seem to be the critical thing here, when i scale the time up or down it gets a lot better. I attached both pictures one withe the "toggeling" made from the RTB and one of "D10" made with the DS1052E.

Hi Rich,

Could you provide some info about current probe deskew on the RTM3000. Is the fixture necessary, do you have suggested values like Tek? It would be smart to provide clear and easily accessible info about such things, it influences scope purchases greatly.

Hi lem_ix,

We do offer a deskew fixture for making power measurements (I'm guessing this is what you meant?) - it is the ZF20.  This will give the most accurate power measurements.  In addition, each active probe in the probe menu will give you an overview of the probe's characteristics (see attached).

Hi Rich,

I just bought two units of RTB-2002. One with MSO upgrade and 100MHz. The other one is a basic unit. I just manage to play with the basic unit at most. I think i have got some bug on the basic unit with latest firmware (02.121) :


* Day 1 - Inverse Brightness : Actually was testing enabling and immediately disabled it. but the signal intensity went very dim and it won't revert back to original state. Situation : 1st time ON device. Solution : secure erase
* Day 2 - Zoom : the vertical scale on zoom windows off by a lot (refer pic) that nothing appear on the zoom window. I need to slide down (Zoom Window) to actually see the zoomed signal while the 'Zoom Square' (Window above) is covering on un-populated area. Meanwhile, pic shown - Zoom window vertical scale start at 150.17mV while the above window start at around -100mV and end at 10mV approx. Situation : 1st time on both channel after trimming the 2nd probe. Noticed it on the square wave gen Zoom, P0. The day before i was playing with FFT. Everything went well with Zoom before this. Problem occur in the morning the other day. I always turn off the Power Source before went to sleep. Solution : secure erase
Sorry I just thought of taking pics when already on my way to 'secure erase' all settings. I need to erase two times in two days in a row after receiving the scope.  problem goes away everytime I 'secure erase' I thought the scope already been a while in the market. why there are too many bugs on my 1st two days?

Please advise.

P/S : Autoset also might be the culprit. I don't know

How do I get previous stable version firmware?
