Chapter 4 System Setup

Out of Service
This check box allows you to place this Input temporarily “out of service”. That is, it will
remain as an entry in your MCA Definition File but will not be available for data
acquisition. It is meant to be used when the MCA or its front-end electronics are
temporarily disconnected.
Memory Groups
This check box allows you to define up to two memory groups, each with an input size
equal to the selected number of channels, which are 32768 by default. At run-time,
acquisition can be directed into either group simply by pre-selecting the group number
before starting to acquire. Additionally, the input size can be changed at run-time to a
value ranging from 256 to 32768 channels.
Each group has its own independent start time as well as independent elapsed times for
PHA groups or sweeps for MCS groups.
Saving the Input Definition
After completing a definition, use the MID Editor’s File | Save (or Save as) command
to save the Definition file.
As a reminder, you’ll see an asterisk (*) next to the name of the current definition in the
Title Bar when a changed definition has not been saved.
CAUTION:
If you change an existing Input Definition, saving it will set its
calibrations to default and will clear the Acquisition Start time.
The File Descriptor
When a Definition is saved for the first time, the Save As file dialog box is automatically
opened. In that dialog box, you’ll see a File Descriptor field, which lets you store a 32-
character description with your file to make it easier to locate when you want to use it
again.
Changing the Summary View
Before going on to see how to edit an existing Input Definition Table, one that you’ve
built previously and saved to disk, there’s one more menu to look at.
The Summary menu has two commands: By MCA and By Input, which change the order
in which the information in the Input Definition Table is displayed. By MCA means that
the first column of the table will display the MCA type that is being used for each entry. If
you choose By Input, the MCA and Input columns will be reversed in the display and the
Inputs will be sorted alphabetically.
You can choose either method, but in the case of systems with a large number of inputs,
By Input is an easier display to understand than By MCA.
