The Tek DPO, based on the 7704 (or possibly the 7704A) was the first
AFAIK.
That would be the Tektronix 7D20 (as a combined timebase/dual channel
scope) which was intended to run at least in the 760x series.
No. The DPO uses an LSI-11 as a 'puter. I have one.
The 7D20 is much later. The DPO separated thye PI and display sections of
the scope with a digitizer unit, maybe the d7001.
10 MHz bandwidth for the 468, and about 70 Mhz bandwidth for the 7D20
(IIRC).
Are you sure about the 70 MHz on the 7D20. I doubt that it was that good
one shot.
The specifications say 70 MHz bandwidth and simultaneous sampling of
40 MS/sec on each channel. I have heard that the bandwidth could be
significantly higher on some units.
