Software Description

ComTec GmbH

5-3

5.1.2. Action

menu

The server program normally is shown as an icon in the taskbar. After clicking the icon it is
opened to show the status window. Using the „

Start

“ menu item from the action menu a

measurement can be started. In the status window every second the acquired events, the
counting rate and the time are shown. Clicking the „

Halt

“ menu item the measurement is stopped

and via „

Continue

“ proceeded.

5.1.3. File

menu

Clicking in the File menu on the Data... item opens the Data Operations dialog box.

This dialog allows to edit the data format settings and perform operations like Save, Load, Add,
Subtract, Smooth and Erase. The Radio Buttons

MPA

,

Selected Spectra

and

New Spectra

provide a choice between handling of the complete data set (MPA) or selected spectra, or to load
new selected spectra for compare. Mark the checkbox

Save at Halt

to write a MPA file containing

the configuration and all spectra at the stop of a measurement. The filename can be entered. If
the checkbox

auto incr.

is crossed, a 3-digit number is appended to the filename that is

automatically incremented with each saving. The format of the data can be ASCII (extension for
separated spectra .ASC), binary (.DAT), CSV (.CSV). If

Separate Header

is not checked, the

Header and data is saved together in a file with extension .MP, otherwise the file with extension
.MP contains only the header and the data is written separately into a file with appropriate
extension. The buttons

Save

,

Load

, and

Erase

perform the respective operation. With

Add

and

Sub

spectra can be added or subtracted from the present data. The checkbox

calibr.

can be

checked to use a calibration and to shift the data then according to the calibration. The

Smooth

button performs an n-point smoothing of selected single spectra. The number of points to average
can be set with the

Pts

edit field between 2 and 21. Check the

Write Listfile

checkbox to write a

listfile during a run.

No Histogramming

prevents calculating any spectra to save computing time

and concentrate the system on writing the listfile.

The menu item File – Replay... opens the Replay dialog. The Replay software is an option, the
licence is either programmed into the MPA4 module or you need an USB dongle.
