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.

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, 

.

This section discusses how to verify the signal in Traditional NI-DAQ 
(Legacy) using channel strings and virtual channels.

The format of the channel string is as follows:

obx

 

!

 

scy

 

!

 

mdz

 

!

 

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 ! scy ! mdz !

 n to verify the signal, where n is a 

single input channel.
