Lynx DSA User's Manual - 9240227J
Interpreting the Definition Entry
As you can see in Definition Table (shown on previous page), adding the entry puts
more than just the name of the MCA in the definition table. We’ll take a brief look at
the other items in the entry now. As we get further into the definition process we’ll
cover them in greater detail. Note the letter following the unit number in each
Definition Table item available: where applicable, an
M
indicates a manually
controlled unit and a
P
indicates a programmable unit.
MCA
This is the type of MCA device being used for this particular entry in the table.
Input
This is the name that will be used to refer to this specific hardware entry in the table.
The MID Editor automatically assigns these names sequentially as
DET nn
, starting
with
nn
=01. You can easily edit this assignment to an input name of your choice via
the
Settings | Input…
menu selection. A unique name is required for each MCA
configuration stored in the MID file.
Size
This shows the number of data channels assigned to this input. By default, the
maximum number of channels (32768) is assigned; this value can be reduced later at
run-time within the Acquisition and Analysis application.
HV
This column describes the High Voltage Power Supply associated with the Lynx
DSP.
Gain
This column describes the DSP Gain device associated with the Lynx DSP.
Other Entries
The other entries, ADC, MXR, and Amp., are not configurable parameters for the
Lynx DSP, however related parameters such as front-end gains can be adjusted later
at run-time within the Acquisition and Analysis application.
Device Setup
The Devices menu sets the parameters for the Lynx's MCA and associated devices.
Some Devices options are disabled (grayed out) because they do not have any
adjustable parameters. Of the enabled Devices, only the MCA and the Sample
Changer has user-selectable parameters. The others default to their only parameter:
Internal.
Note: At this point in the setup process the Lynx is required to be connected to the
network or directly to the host computer. Note the device's IP address or
UPnP name as it will be required to complete the setup. Refer to the
Communications Setup Appendix
starting on page 150, as it describes the
initial setup and basic operation of the communication interfaces.
