Each channel consists of two terminal connections specific to that channel as shown in Table 2.
You can verify or adjust the accuracy for any or all channels depending on the desired test
coverage. Refer to Figure 2 and only connect the input channels required for verification or
adjustment in parallel.
Refer to Table 2 for the analog signal names of the TB-4304.
Complete the following steps to connect the TB-4304.
1.
Install the PXIe-4304/4305 and the TB-4304 in the PXI Express chassis according to the
instructions in the
NI PXIe-4304/4305 and TB-4304 User Guide and Terminal Block
Specifications
.
2.
Configure the PXIe-4139 to voltage output mode and enable remote sensing. Connect the
PXIe-4139 output to the TB-4304 as shown in Figure 2.
