A 3.3.4 Triggering
A 3.3.4.1 Select Trigger Source
TRIGGERSOURCE [NONE | SYNCTRIG | TRIGIN | SOFTWARE | ENCODER1 | ENCODER2 | ENCODER3]
The trigger source triggers the triggering process.
- NONE: No trigger source
- SYNCTRIG: Use Sync/Trig input
- TRIGIN: Use TrigIn input
- SOFTWARE: Triggering is caused by the TRIGGERSW command.
- ENCODER1/ENCODER2: Triggered by encoder1 or 2.
- ENCODER3: Triggered by encoder3 (ENCODER3 must be switched on)
A 3.3.4.2 Output of Triggered Values, With/Without Averaging
TRIGGERAT [INPUT | OUTPUT]
- INPUT: Triggering the measured value recording. When calculating the mean, mea- sured values immediately before
the trigger event are not included; instead older measured values are used, which were the output in previous trigger
events.
- OUTPUT: Triggering the measurement value output. When calculating the mean, measured values immediately be-
fore the trigger event are used.
Triggering of measured value recording is enabled as a factory default setting.
A 3.3.4.3 Trigger Type
TRIGGERMODE [EDGE | PULSE]
Defines the trigger type. Only enabled if TRIGGERSOURCE has been set to SYNC or TRIGIN.
- PULSE: Level triggering
- EDGE: Edge triggering
A 3.3.4.4 Active Level Trigger Input
TRIGGERLEVEL [HIGH | LOW]
- HIGH: Edge triggering: Rising edge, level triggering: High-active
- LOW: Edge triggering: Falling edge, level triggering: Low-active
A 3.3.4.5 Software Trigger Pulse
TRIGGERSW
Creates a software trigger pulse, if Software is selected as trigger source. With low measuring rates < 2.4 kHz and FFT
signal selected, unreliable trigger information may occur.
A 3.3.4.6 Number of Output Measurement Values
TRIGGERCOUNT [NONE | INFINITE | <n>]
- NONE: Stop triggering
- <n>: Number of measurement values which are displayed after a trigger impulse when edge triggering or software
triggering.
- Infinite: Start infinite output of measurement values after a trigger impulse when edge triggering or software trig-
gering.
A 3.3.4.7 Trigger Level TrigIn
TRIGINLEVEL [TTL | HTL]
The level selection only applies for the TrigIn input. The Sync/Trig input expects a differential signal.
- TTL: Input expects TTL signal.
- HTL: Input expects HTL signal.
