PXIe-5653 Synthesizer/LO Source Front Panel Connectors (Continued)
Connector
Use
LO2 OUT
Connects to the LO2 IN connector on the PXIe-5603 or PXIe-5605
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-5603 or PXIe-5605
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).

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-5622
CLK IN connector.
