2.5 - Functional Command & Configuration
The main panel is divided into two functional groups: Command, and Configuration. The
Command
Group
allows the user to initiate certain process/system commands. The
Configuration Control Group
contains the controls necessary to set different configuration parameters into the 90PGA.
Command Group
1 - Quit Command Button:
Use this command button whenever you want to exit/close the software. It
will then no longer allow configuration changes; close the function card panel and turn-off the SCC
without affecting any other active slot card process.
Configuration Control Group
Input Configuration Controls:
Use these controls to select the input configuration modes for the slot card.
2 – Coupling Mode Selection:
Set the coupling mode for each channel in the function card with the AC/DC
control. Select
AC
for AC coupling mode or
DC
for DC coupling mode.
3 – Input Mode Selection:
Sets the input mode for each channel in the slot card. Select
Single-Ended
for
single-ended input operation or
Differential
for differential input mode.
4 – Gain Control:
This control sets the gain (0 to 64.5 in 0.5dB steps) for each channel on the slot card.
5 - Offset Control:
This control sets the signal DC offset value (-100 to 100 in 1mV steps) for each channel on
the slot card.
6 – Load CFG Control:
Use this command button to load a selected configuration from a selected slot card
channel. This will load ONLY the configuration parameters for the selected channel/configuration pair. After
loading the specified configuration, the display indicators representing the configuration parameters for the
selected channel will be refreshed. Allow a ten (10) second delay for refreshing of the GUI.
7 – Save CFG Control:
Use this command button to save a selected configuration from a selected slot card
channel. This will save ONLY the configuration parameters for the selected channel/configuration pair.
8 – CFG Control:
Use this control to set the desired configuration number. Numbers go from one (1) up to nine
(9) inclusive.
9 – CH 1 - CH 2 Control:
Use this control to select the channel to be used in the saving (Save CFG) or loading
(Load CFG) configuration operations. This control is ONLY used for configuration selection purposes.
