Probe
20. BNC Connector. This is the input connector for a X1 or X10
probe.
21. CAL OUT. This pin jack outputs the calibration signal used to
compensate the X10 probe. DC Restorer must be OFF (page 1 of
the Configure menu) and EXT REF must be selected.
Display Mode
Companion Switches. Some switch functions are paired or grouped so
that two or three switches determine one display. These are referred
to in this manual as companion switches.
Pushing the same companion switch twice in succession will change
its selection (as indicated by the LED).
A Held mode will be exited when its companion switch is pushed,
and then the HELD switch is (momentarily) pushed again. The
switch setting will revert to the last selection before the Held mode
was entered.
Pushing first one companion switch and then another will cause the
display to alternate between the first switch selection and the second
switch selection.
NOTE. Some switches may be locked out by menu selections.
Companion Switch Example. VECT / SCH and XY / PIX are used to
select vectorscope CRT displays.
Push and release the VECT/SCH switch to select Vector. It will
require one or two pushes.
Now push and release the XY / PIX switch to select XY.
Push the VECT / SCH switch. Note that it is restored to Vector.
Push the XY / PIX switch. Note that it is restored to XY.
Push the XY / PIX switch a second time. Now it toggles to PIX.
Push the VECT / SCH switch twice. Now it toggles to SCH.
