Table 10. PXIe-5653 Synthesizer/LO Source Front Panel Connectors
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 V
pk-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
