Table 3. PXIe-5603 or PXIe-5605 RF Downconverter Module Front Panel Connectors
Connector Use
RF IN Connects to the analog RF input signal to be measured by the PXIe-5665.
Note The PXIe-5603 or PXIe-5605 downconverter module has no
internal DC block. High-frequency components in the
PXIe-5603 or PXIe-5605 can be damaged when DC signals are
applied directly to the RF IN connector. The PXIe-5665 ships with an
SMA DC block attached to the RF IN connector to prevent damage
to the device when a DC input signal is present. The DC block must
be removed to make measurements below 10 kHz. NI recommends
that you keep the DC block attached to the RF IN connector for all
measurements at frequencies greater than or equal to 10 kHz to
maximize the accuracy of the device. If the RF attenuation is set to
0 dB with the DC block attached, an input DC voltage greater than
±2 V may damage the internal components of the downconverter. To
prevent damage to the downconverter, ensure that the DC voltage at
the RF IN connector is between -2 VDC and +2 VDC. With the DC
block removed, the maximum allowed voltage is 0 VDC.
Caution To reinstall the DC block on the PXIe-5603 or PXIe-5605
