HP 54121A DC to 20 GHz, Four Channel Test Set with ribbon cable

Sampling oscilloscope from the heyday of America.
I am developing soil analysis pulse reflection instruments. I bought it as a spare part for this. Channels 3 and 4 work in it. I just needed those special cables. The cable is working properly. The Hp 54123/54121 sampling measuring system is one of the best devices in the world. Easy and simple to service.

Old logic analyzer in a timeless design
This HP1652b logic analyzer is ideal for high voltage pulse technology because the input trigger level can be adjusted up to a signal level of + -10 V. However, it also includes a 100MHz oscilloscope with 2 channels and an automatic pulse evaluation function. Unfortunately, its oscilloscope is only 6 bits, but it can still be used very well for work.

Excellent flexible bert tester
Unfortunately telecommunications equipment manufacturers have forgotten radio telemetry.
That is why older Bert testers are forced to use it.
They have a burst mode BERT testing function.
Agricultural telemetry is in serious progress.
It would be nice to have lightweight and small flexible BERT testers on the market.
