Test Equipment

Table lists the equipment recommended for the performance verification and adjustment 
procedures. If the recommended equipment is not available, select a substitute using the 
requirements listed in Table 1.

Connecting the TB-4322

Caution

Always have the NI PXI Express chassis powered off when inserting a 

module into the chassis.

The TB-4322 terminal block provides connections to the NI PXIe-4322. Figure 1 shows the 
connector location for each TB-4322 channel.

DMM

NI PXI-4071

Use a DMM that can provide both voltage and 
current measurements.

Accuracy of 20 ppm or better in the smallest range 
to measure 16 V, and offset error of 2.4 µV or 
better in the smallest range to measure 1 V.

Accuracy of 165 ppm or better in the smallest 
range to measure 20 mA, and offset error of 3 nA 
or better in the smallest range to measure 100 µA.
