Setting The Input Configuration - Keithley DAS-800 series User Manual

The Expansion Board Configuration for Keithley DAS-800 Series
Notes:
dialog in DriverLINX allows you to record the settings of your analog
input multiplexers and enable the expansion channels. Make sure that the
switch settings match the settings you define in DriverLINX. Refer to the
Using DriverLINX with Your Hardware—Keithley DAS-800 manual.
On models DAS-801 and DAS-802, using a multiplexer requires setting
the associated base channel's switch to single-ended.
The DriverLINX Analog Input subsystem has 8 analog input single-ended
or differential signal connections depending on the model of your
DAS-800 board. DriverLINX maps these signals to Logical Channels.
DriverLINX uses several of these control connections for external clock,
trigger, and gating inputs. Refer to the Using DriverLINX with Your
Hardware—Keithley DAS-800 manual.
All DAS-800 Series boards have 8 analog input channels. On DAS-801
and DAS-802 models, you can switch each channel to differential or
single-ended. The switch setting affects only the connections for the
channel. DriverLINX grays out this property in the configuration dialog.
Setting the Input Configuration
DAS-801 and DAS-802 boards are shipped with the input configuration
for all channels set to single-ended. If this is not appropriate for your
application, you can reconfigure the input configuration on a
channel-by-channel basis using the input configuration switch block
(labeled S1).
Note: The default input configuration in the DriverLINX configuration
file is also single-ended for all channels. Make sure that the switch
settings match the settings you establish in DriverLINX.
The input configuration switch block contains eight switches, labeled 1
through 8. Switch 1 corresponds to channel 0; switch 2 corresponds to
channel 1, and so on. The location of the input configuration switch block
on the DAS-801 and DAS-802 boards is shown in Figure 3-2 on page 3-3.
