A second part of the question (if the answer is different) - which was the first Tektronix scope to have cursors.
Cursor voltage measurement on a Tek scope would have been possible in
1974, certainly. With a 7D12/M2 plugin the timebase delay settings can
be used to highlight a portion of trace for voltage measurement, and
any delayed timebase with a calibrated delay will effectively do
cursor time measurement. If you want on-screen digital readout of
delta-delayed time that comes in 1976 with the 7B85. So in the 7000
series scopes, I'd say that manually-controlled digital cursor
measurements of time and voltage were possible together for the first
time in 1976.
