Table 3. Connector Descriptions
Connector Description
RF IN

Connects to the analog RF input signal to be measured by the vector signal analyzer.

IF OUT

Connects to the IF IN connector on the IF digitizer front panel.

This connector is the output terminal for the frequency-translated IF signal.

LO1 IN

Connects to the LO1 OUT connector on the PXIe-5653 front panel within the vector signal analyzer.

This connector is the input terminal for the LO1 (3.2 GHz to 8.3 GHz) source.

LO2 IN

Connects to the LO2 OUT connector on the PXIe-5653 front panel.

This connector is the input terminal for the LO2 (4 GHz) source.

LO3 IN

Connects to the LO3 OUT connector on the PXIe-5653 module front panel.

This connector is the input terminal for the LO3 (800 MHz) source.

LO1 OUT

Output terminal for the LO1 (3.2 GHz to 8.3 GHz) source. In multichannel systems, LO1 OUT exports the signal received at LO1 IN to other PXIe-5606 modules.

LO1 OUT is disabled by default.

LO2 OUT

Output terminal for the LO2 (4 GHz) source.

This signal is connected to the CLK IN connector of the PXIe-5624.

When used in within the PXIe-5668, this signal is enabled by default.

LO3 OUT

Output terminal for the LO3 (800 MHz) source. In multichannel systems, LO3 OUT exports the signal received at LO3 IN to other PXIe-5606 modules.

This connector is disabled by default.

IF IN / BIAS OUT

Connector for IF input and current source for biasing external mixers.

NOISE SOURCE

HD BNC connector for enabling noise source on or off to facilitate noise figure measurements.

Table 4. LED Indicators
LED Indication
ACCESS

Indicates the basic hardware status of the module.

OFF—The module is not yet functional, or the module has detected a problem with a power rail.

AMBER—The module is being accessed. Accessed means that the device setup registers are being written to in order to control the device.

GREEN—The module is ready to be programmed by NI-RFSA.

ACTIVE

Indicates the module state.

OFF—The module is in a quiescent state.

AMBER—The module is waiting for the Advance Trigger from the configuration list.

GREEN—The module is triggered and is running a step from the configuration list.

RED—The module has detected an error state. An error state may indicate the module has exceeded approved operating temperature and thermal shutdown has occurred or that the module has detected a power supply failure. If the power supply fails, contact NI technical support.
