EEVblog 1583 - Advanced Oscilloscope Triggering: Glitch/Pulse/Runt/Interval

(1/2) > >>

EEVblog:
A practical demonstration on how to use advanced oscillocope trigger features to trigger on an unsyncronised infrequenct runt/glitch pulse.
Includes Pulse/Glitch, Runt, Interval, Zone triggering, and infinite persistence display, and waveform update speed demonstrated and explained.
Using the Rohde & Schwarz MXO4, Siglent SDS2154X HD, Keysight 3000T, Tektronix Series 2, and the Rigol DHO800.

Hi!

I originaly posted this in supporters lounge, but since you already have published it, I moved it here..

I have two comments.

At 14.09 I'm not sure "Find level" works exactly like you think. AFAIK, that is same "Find level" like when you press trigger level knob on Keysight. Your glitch is at signals mid level...
Same functionality exists on Siglent trigger level knob , Rigol probably too.
Nothing special to any glitch finding. Just set trigger level at half the signal.
That needs to be researched a bit more, maybe.

R&S MXO 4 Series manual:
Find level
Sets the trigger level automatically to 0.5 * (MaxPeak – MinPeak).

LeCroy WaveScan does detailed analysis of signal and finds these things automatically..

Second, it might be nice to mention that Siglent SDS2000X HD (unlike R&S) has functional zone trigger, pretty much same as MSOX3000T.

Apart from that , nice and useful video for beginners.  :-+

Best,
 Sinisa

Nice video Dave!

I actually made a video that goes through most of the MXO trigger types and how to configure them.

Ah, fooled  :(
Entirely coincidence there was a glitch at the mid point in this case.

Interesting, sounds like the industry leader in this case then.

It does, but given that zone trigger isn't the thing to use here, I didn't mention it twice.

Nice. When do I get zone triggering?  ;D
