REMOTE CONNECTORS AND SWITCHES
H I GH, LOW, O F F
The three-position switch i s located o n the
left side·panel of the R7844 and on the
rear panel of the 7844
BNC connector. Remote single-sweep re-
set (A and B H O R I Z) with compatible
time-base units
Switching from the high level (+50 V to
+ 1 0 V; sink less than 40 MA) to the low
level (+0.5 V to -5 V; sink less than 1 0
rnA), i n less than 1 ms, resets the sweep
1 0 /15 at 50% amplitude points
+50 V to -5 V
