This tab has the following input fields.
Threshold for trigger and event input
Sets threshold level.
Polarity for trigger and event input
Sets the polarity for the input.
Positive – rising edge
Negative – falling edge
Either - both
Impedance for trigger and event input
Sets the impedance of the input.
Low – 50 Ohm
High – 1k Ohm
Internal trigger frequency
Sets the frequency of the internal trigger generator. For details on frequency range
and resolution, refer to M8190A Data Sheet.
Trigger /Gate selection switch
Selects between external trigger input and internal trigger generator.
Enable Event selection switch
Selects the source for the enable event, either trigger input or event input.
Advancement Event selection switch
Selects the source for the advancement event, either trigger input, event input or
internal trigger generator.
Trigger /Gate hardware input switch
Enable or disable the trigger hardware input for channel 1 and channel 2. Used
when Trigger mode is set to Triggered/Gated. Trigger can be provided either
internally or externally. However, only one type of triggering can be enabled at a
time (Internal Trigger or Trigger In). There is no way to provide separate triggering
to both the channels. However, there is a provision of enabling the trigger on one
channel, if required. In order to perform this, uncheck the channel coupling from
the Clock tab. This is used only to enable the waveform.
When Trigger mode is set to Gated, same input works as a gateway to
enable/disable the waveform being played on the channel. The control to enable
and disable the waveform is provided in Status/Control Tab as “Force Trigger”
option.
Enable Event hardware input switch
Enable or disable the event hardware input for channel 1 and channel 2. Used
when working in armed mode and is used only in the beginning. Once the user hits
the RUN button, the downloaded waveform could be seen on the channel only
when “Force Enable” is performed.
