My DPO

The pictures on this page show my DPO. The serial number and the GPIB Interface indicate that it was produced in mid 1978. The configuration sticker identifies it as a WP1110 system. So I think it was delivered together with a 4050 series computer, most likely the 4051.

2x 7A16A, 7B70 and 7B71 was the default plugin configuration in the early years.

The P7001 is still in nice cosmetic shape.

The rear view of my DPO. The system has a total power consumption of up to 300W. That’s why I decided to add a cooling fan. Tektronix chose the same cooling solution for the latest generation of the 7704A. I’ve used a spare panel for this modification. So it can be reversed at any time.

My first mechanical prototype of the USB+ interface used countersunk screw heads. But then I realized that most of the other screws on the rear of the DPO are pan-head screws. So I’ve changed that in my final design.

The unit came with a 021-0206-00 GPIB Interface. It’s a complex dual-board design, powered by the Motorola 6800 CPU. This interface increases the power consumption of the DPO by almost 25 watts!

My DPO is also equipped with a Hardware Signal Averager (HSA) module. Almost nothing is known about this module. See Help needed.
