ScanImage 2018 : Laser Trigger Scope

LASER TRIGGER SCOPE Panel

 

Overview


The Laser Trigger Scope panel is used for viewing and configuring a sampling window for low rep-rate laser support

Icon

The Laser Trigger Scope panel can be accessed by selecting View->Laser Trigger Scope from the MAIN CONTROLS interface menu.

Main Panel


Laser Trigger PlotWhen the scope is active, this shows traces of the laser trigger. This can be used to determine if filtering is needed. The X axis is in "Ticks" with one tick equal to the sample rate of the digitizer.
PMT Signal Plot

When the scope is active, this shows traces of the PMT signal for the selected channel. The plot is overlaid with the sampling window in green that is applied based on the settings. The sampling window can be moved by clicking and dragging in the green area or resized by clicking and dragging the edges.

Trigger Filter

Sets the debouncing filter level for the laser trigger. Zero disables the filter while increasing the value increases the filtering

Detected Frequency

Shows the frequency of the detected laser trigger in MHz. This will update when the scope is enabled.

 

Detected Period

Shows the period of the detected laser trigger in ticks (digitizer sample periods). This will update when the scope is enabled.

Enable MaskEnables masking of samples based on entered settings. When this is enabled changes to settings take effect immediately
DelayNumber of samples after laser pulse to ignore
WidthNumber of samples to include after the ignored samples
Save SettingsSaves the entered settings to the Machine Data File. Saving settings avoids needing to repeat this setup again.
ChannelSelect the acquisition channel to show in the PMT signal plot
Capture NSet the number of samples to show in the plot. Data is divided at detected laser pulses and each detected pulse is plotted as a separate trace. Increasing this number will show more traces
Start/Stop ScopeEnables or disables the live scope display.
