Show us your square wave

MadTux:
Thanks for the pictures. I'm always curious how test gear looks from the inside.

tautech:
While nothing to get real excited about, I don't remember a Siglent SDG5082 square wave posted here.
Had one of these through my hands today, quite liked it, nice UI.

As in all my prevoius posts:
50 Ohm source and internal termination.
1 m RG58
Scope SDS2304

30 MHz @ 40% duty, 70 mV P-P

rolycat:
Couldn't find any posts for the Tek MDO3000 series, so:

A 25 MHz square wave from the AFG on an MDO3054 to the same scope.
Connection is 0.5 m RG58, 50 ohm source and internal termination.

A nice clean signal with a decent rise time and low jitter.

mmagin:
HP 209A ($110 from ebay, seems to work perfectly) at its maximum 2 Mhz, connected to HP 54645A scope with banana-bnc adapter, coax, and 50 ohm termination, scope plotting over gpib - still figuring that out -- those rectangles should be squares :)
  This is a little better.

I will follow up somewhat later with the results of a 74LVC sine-to-square converter connected to my gpsdo 10mhz source.  I need more amplitude into my 35 year old microwave frequency counter's ref input.

Finally got around to setting up my 54120B on the bench, first time using this scope, this is what I got up and running about five minutes from switching on. I'm using a 54121A TDR test set with a short on the TDR/Ch1 channel for the pulse. Total of $700 of TE from ebay, in three separate auctions for the 54120B, 54121A and interconnecting cable, the cable cost almost as much as the 54120B.

I suspect once I figure out what I'm doing with this scope I might be able to improve on it.
