Table 11. Connector Descriptions
Connector Description
REF IN 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/LO module onboard 100 MHz OCXO.
LO1 OUT 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 Output terminal for the LO2 (4 GHz) source. LO2 OUT is an SMA connector with an impedance of 50 Ω (nominal).
LO3 OUT Output terminal for the LO3 (800 MHz) source. LO3 OUT is an SMA connector with an impedance of 50 Ω (nominal).
Table 12. LED Indicators
LED Indication
ACCESS

Indicates the basic hardware status of the module.

  • OFF—The module is not yet functional, or the module 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.
    • ACTIVE

    Indicates the module state.

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