1378 Refer to the user documentation for required maintenance measures to ensure user safety and/or preserve the specified EMC performance.
1378 The signal pins of this product's input/output ports can be damaged if subjected to ESD. To prevent damage, turn off power to the product before connecting cables and employ industry-standard ESD prevention measures during installation, maintenance, and operation.
1378 If this device has been in use, it may exceed safe handling temperatures and cause burns. Allow the device to cool before removing it from the chassis.

Connector Use
REF IN

Routes a frequency reference signal to the RF synthesizer/LO source.

This connector accepts a 10 MHz frequency signal with a maximum voltage of 2 Vpk-pk.

REF OUT (10 MHz) Routes a frequency reference signal from the synthesizer/LO module onboard 10 MHz oven-controlled crystal oscillator (OCXO).
REF OUT (100 MHz)

Routes a frequency reference signal from the synthesizer onboard 100 MHz OCXO.

LO1 OUT

Connects to the LO1 IN connector on the PXIe-5606 module front panel.

This connector is the output terminal for the LO1 (3.2 GHz to 8.3 GHz) source. LO1 OUT is an SMA connector with an impedance of 50 Ω (nominal).

LO2 OUT

Connects to the LO2 IN connector on the PXIe-5606 module front panel.

This connector is the output terminal for the LO2 (4 GHz) source. LO2 OUT is an SMA connector with an impedance of 50 Ω (nominal).

LO3 OUT

Connects to the LO3 IN connector on the PXIe-5606 module front panel.

This connector is the output terminal for the LO3 (800 MHz) source. LO3 OUT is an SMA connector with an impedance of 50 Ω (nominal).

LED Indications
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 state of the module.

OFF—The module is not generating a signal.

AMBER—The module phased-locked loops (PLLs) are attempting to lock.

GREEN—The module is generating a signal; applicable PLLs are locked.

RED—The module has detected an error state. An error state may indicate the module detects a PLL lock failure, is exceeding approved operating temperature and is in a state of thermal shutdown, or the module detects a power supply failure. If the power supply fails, contact NI technical support.

Note The PXIe-5653 LO source has 10 MHz and 100 MHz reference outputs. For best performance, connect the 100 MHz REF OUT connector to the PXIe-5624 CLK IN connector.
