Cursor measurements on trace A, B or M if A
and B are on; M if Mathematics... is on, see
ScopeReadings and Waveforms on page 6.
OFF: Switch cursor measurements off.
Triggering
Triggering tells the test tool when to begin displaying the
waveform.
Automatic triggering assures a stable display of virtually
any signal:
Perform an auto set. AUTO appears at the
top right of the screen. Input A is the default
trigger source.
Now you can take over basic trigger controls such as
source, level, slope and delay:
Display the trigger key labels
A B : trigger on input A or B waveform
Ext : trigger on the meter-input signal.
Select the trigger slope (dual slope for C
versions).
Select trigger level control:
• at automatic triggering via input A or B
(AUTO TRIG):
AUTO LEVEL : automatic level control.
MANUAL : manual level control.
• at triggering via the meter input (Ext):
0.12V 1.2V : select level 0.12V or 1.2V.
• at triggering on edges via input A or B
(EDGE TRIG, see F4 below):
LEVEL : adjust the level manually.
Use to adjust the trigger level.
Select trigger options:
 Automatic... : automatic triggering on
signals >1 Hz or > 15 Hz (faster).
 On Edges... : turns off automatic triggering
and opens the Trigger on Edge menu:
Update: (screen update)
□ Free Run : the test tool updates the trace
even if there are no triggers.
□ On Trigger : the screen is updated only
when valid triggers occur.
□ Single Shot : the test tool waits for a
trigger. After receiving a trigger, the
waveform is displayed and the
