Tektronix oscilloscope demo board
« on: February 08, 2023, 06:41:56 pm »
I'm not related to the seller.

https://www.ebay.com/itm/275626311774

40$ is cheap if you were looking for one of those board.

Documentation is here: https://download.tek.com/manual/071071500.pdf

Oh why not? Ordered.  8)

Test oscilloscopes ? those demo boards normally generate interesting signals that a function generator normally can't.

For example, the one listed has a fast rise pulse of 200ps.

More specifically, they generate signals to show off specific features that would sell a particular series of scope over the competition. Like something requiring a specific triggering mode, or protocol decoding, or a high waveform rate.

I would generally not call them particularly useful outside sales and maybe training, but I could see the fast rise output being useful.

This one is quite generic in term of signals (switcher noise, USB stream, QAM modulation, Random anomalies, Fast rise, VCO, etc ..). Don't need a specific Oscilloscope to be used.

But since it was targeting the Tektronix TDS7000 series it might has been designed toward higher bandwidth scopes.

I received the board today. Looks like NOS, unopened package, manual shrink-wrapped.

The board is very high quality, very industrial, simple presentation to user.

I tried looking at several of the boards test signals with my newish SDS2202X-E. First was QAM modulation using XY mode.

The other was a square wave with an anomaly (glitch). You can change the randomness of the anomaly by pressing a button on the board as many times as you wish. I was easily able to capture the glitch continually using the trigger function "pulse" and setting it to a "<=" value of ~ 1 uS.

Will try several other signals tomorrow.

I'm guessing the glitch was to show off the high waveform/S, or maybe the DPO / intensity grading functionality. By making it rarer, a sales engineer might be able to create a signal that would show well on the Tek scope but not on a competing Lecroy/Agilent scope.

Yeah, the demo board had waveform anomalies that highlighted the fact that Tek's high waveform trigger rates, were not only fast in the FastAcq / DPO mode, but they weren't bursty like some competitors that claimed to have fast waveform trigger rates.    Competitors would say "But it only does it in that mode."  Tek response was easy...  Yes, that's true, but if you don't know what the problem is, to define a trigger to nail it every single time, it really doesn't matter much....    It was brutal, put an Agilent/LeCroy scope on that signal and everything looked fine, meanwhile the Tek scope would be showing a crap load of signal issues.   That demo board made a lot of money showing real performance.

Another nice use of that demo board is run the fast edge out the SMA to a scope channel input terminated in 50 ohms.   At the same time you can probe that edge with a single ended or differential probe and see 1) how much slower the probe is, due to it's bandwidth, and 2) how much the probe loads the signal, impacting the circuit.   

It's quite visual....
