The OMP40 probe can be in one of three modes:
1.
Stand-by mode - The OMP40 uses a small
current, while passively waiting for a switch-on
signal to be received via the probe’s receiving
diodes.
2.
Operating mode - Activated by one of the
switch on methods described on page 29.
Signals are only transmitted by the probe
in this mode showing that the probe is now
ready for use.
3. Programming mode - The Trigger Logic
programming method allows a number of
probe set-up options to be programmed by
triggering the probe, including the switch-off
options described on page 29.
MI7 interface unit
CAUTION: Systems using the earlier MI7
interface in place of the MI 12 interface
are not compatible with OMP40.
