8. Click the Device tab.
9. Enter the appropriate information on the Device tab.
10. Click the Test button.
11. Click the Start button.
12. After you have completed verifying the channels, click the Stop
button.
You have now verified the SCXI-1125 configuration and signal connection.
Note For more information on how to further configure the SCXI-1125, or how to use
LabVIEW to configure the module and take measurements, refer to Chapter 4, Theory of
Operation.
Verifying the Signal in Traditional NI-DAQ (Legacy)
This section discusses how to verify the signal in Traditional NI-DAQ
(Legacy) using channel strings and virtual channels.
Verifying the Signal Using Channel Strings
The format of the channel string is as follows:
obx ! scy ! mdz ! channel
where
•obx is the onboard E Series DAQ device channel, with x representing
a particular channel where the multiplexed channels are sent. This
value is 0 for E Series DAQ device channel 0 in a single-chassis
system. In a multichassis or remote chassis system, the E Series DAQ
device channel x corresponds to chassis number n – 1, where E Series
DAQ device channel x is used for scanning the nth chassis in the
system.
•scy is the SCXI chassis ID, where y is the number you chose when
configuring the chassis.
•mdz is the slot position where the module is located, with z being the
particular slot number. The slots in a chassis are numbered from left to
right, starting with 1.
•channel is the channel that is sampled from module z.
Use the format ob
x
! sc
y
! md
z
! n to verify the signal, where n is a
single input channel.
