to submenus:
SCOPE OPTIONS ...
SCOPE MODE
• NORMAL: the scope mode commonly used.
• SINGLE SHOT: can be used to catch single
events.
• ROLL MODE: is useful for monitoring lower
frequency waveforms.
WAVEFORM MODE
• NORMAL: the mode most commonly used.
• SMOOTH: is used to suppress noise.
• ENVELOPE: envelope records all values of
live waveforms. On the screen the resultant
envelope is displayed.
PROBES ...
• PROBE on A: for selection of the correct
probe type when using non-standard probes.
• PROBE on B. Identical to Input A description.
• PROBE AC ADJUST. For adjustment of 10:1
voltage probes other than the probe supplied
with Fluke 124. This is necessary for correct
high frequency measurements.
TRIGGER ...
• INPUT: selection of the trigger source on
which the Test Tool is triggered. EXTernal
triggering is possible via an optically isolated
trigger probe.
• SCREEN UPDATE: FREE RUN gives
automatic screen update even if there are no
