Source
Selects the source of the trigger signal for the current trigger condition. The trigger
source works even if it is not displayed in a diagram. It must be synchronized to the
signal to be displayed and analyzed.
The trigger source can be:
●
Channel 1...4: An analog input channel
●
Extern: External analog signal connected to the external trigger input
The external trigger source is supported for the "Single event" sequence. It is not
available if a longer trigger sequence is selected, or if qualification is enabled.
●
Line: The instrument generates the trigger from the AC power input and synchroni-
zes the signal to the AC power frequency. Use this source if you want to analyze
signals related to the power line frequency, such as lighting equipment and power
supply devices.
●
Serial bus, D0...D15, Logic, Parallel bus 1...4:
If options with trigger functionality are installed, the variety of trigger sources is
enhanced with specific trigger sources.
Available sources depend on the trigger sequence setting. If "Single event" is selected,
all inputs (analog input channels, serial and parallel buses, digital channels) can be
used as trigger source. If any other trigger sequence is selected, only channel inputs
Ch1...4 can be set as trigger source, and all other input sources are disabled.
