A LOW to HIGH transition indicates that the
trigger occurred. The logic level for Vout
(HI) is
≥
3.25V open circuit;
≥
2.2 V into a
50
Ω
load to ground. The logic level for
Vout (LO) is
≤
0.4 V into a load of
≤
4 mA;
≤
0.2 V into a 50
Ω
load to ground.
3. Probe Power
. Use this port to provide
auxiliary power for TekVPI probes, when
needed.
4. Video Out
. Use the Video Out port (DB-15
female connector) to show the oscilloscope
