Measurement View

The Measurements Device(s) page consists of a wide display area, with configuration and control elements below. The measurement data are displayed as time count rate curves in counts/sec as a function of acquisition time.

acquisition_windows

The various elements are described below:

tb-settings

Button to access the configuration panel.

Button_normalization_to_1_display

Normalization: Scales all curves relatively with a maximum of 1.

Button_curve_autoscale

Autoscale: If enabled, the program continually adjusts the curve display ranges (both X and the Y axes).

Button_update_during_acq

Update box: If enabled, the display is continually updated to show all the acquired data.

Integration time

Duration during which the counts are collected. The accumulated counts are then divided by the integration time to calculate the count rate. Default is a 1 sec integration time, the minimum. The maximum Integration time is 10sec. Note that rebinning to longer intervals can be performed later in the correction tool.

Button_correction

Button to transfer the acquired curve(s) to the PSAMPLE Correction tool.

Button_clear_acq

Button for clearing the data buffer.

Button_clear_start

Clear box: If enabled, the data buffer is cleared when starting a new acquisition. I.e. upon the re-start of an experiment the acquisition will overwrite the existing measurements. If disabled, the acquisition will continue from the moment the experiment was stopped.

tb-tab-capture

Creates a capture of the entire screen and adds it to a buffer of up to 20 captures.

tb-console

Opens the PMOD console window with log information.

Button_END_by

The End By supports two settings:

User: allows stopping the acquisition any time by activating the STOP button.

Time: the user can define the acquisition duration, in minutes, after which the measurement is automatically stopped.

Counts: the user can define a threshold after which the measurement is automatically stopped.

Button_Arrow_up

Device Info: Shows the device configuration.

Hide/Show Controls: Allows the curve control elements to be shown or hidden.

Define/Save Protocol: For the definition of an acquisition protocol.

Load Protocol: To retrieve an acquisition protocol.

ACQ_Start, ACQ_Start_All

Start: Starts the acquisition for the configured device. Start All starts the acquisition on all configured devices at once.

ACQ_Stop

Stop: Stops the acquisition for the configured device. Stop All stops all devices at once.

timestampButton

Timestamp: Opens a dialog in which the user can record events during acquisition with time stamping. Events can be entered manually and written to a file using the Set button.

timestampDialog

The events file will be saved along with counts data, with the suffix *_EVTS (format *.crv).

If more than one device has been configured, each if them is represented by a curve/control area as described above (maximum 5).
