acquisition. The calibration curve is fitted as a linear, quadratic, or cubic fit depending on the
number of channels in the file. The calibration units are set to “???” to indicate that the units did
not come from the file. In addition, an MCS calibration table (
.MCT ) file is also generated which
shows the calibration points selected during the import process.
6.1.9. Export ASCII...
The Export ASCII... command writes the displayed data to an ASCII text file with the default
extension
.ASC . When this command is selected, a standard file-save dialog opens. Enter a valid
filename (consisting of an optional drive and directory, a filename, and an optional extension)
and click Save. If the specified file already exists, a message box opens asking you to verify the
entry or cancel the operation. Click Yes to overwrite the existing file. A progress indicator at the
bottom of the screen will track the duration of the save.
The entire spectrum is saved to disk. The data format for the text file consists of a list of two-
element lines. Each line is composed of the calibrated value (floating point) and the counts
(integer) separated by spaces. This is also the format read by the Import ASCII... command.
Figure 28 shows the layout of an exported ASCII file.
6.1.10. Exit
This exits MCS-32 and returns to Windows. If the buffer contains a spectrum that has not been
saved, a warning message is displayed to allow you to save. Any JOBs are terminated. If data
acquisition is in progress, acquisition will continue — the hardware can continue data collection
even if the software is not active.
6.2. Acquire
The Acquire menu is shown in Fig. 29. The Start, Stop, and
MCS > Buffer commands are active only in MCS mode.
6.2.1. Start
The Start command initiates data collection in the selected
MCS. You can also start the MCS with the <Alt + 1> accel-
erator, or by clicking the Start button on the Sidebar. See
Pass Control... (Section 6.2.5) for information on what takes
place when you select Start.
6.2.2. Stop
Stop terminates data collection in the selected MCS. The MCS
can also be stopped with the <Alt + 2> accelerator or by clicking the Stop button on the Sidebar.
