2. Connect the TX chassis to the mmRH-3647.
a)
Connect the DIGITAL I/O connector of the PXIe-3620 front panel in the TX chassis
to the CONTROL connector of the mmRH-3647 back panel using an EPLSP cable.
b) Connect the TX LO1 connector of the PXIe-3620 front panel in the TX chassis to
the LO IN connector of the mmRH-3647 back panel using an SMA(m)-to-SMA(m)
cable.
c) Connect the TX IF OUT connector of the PXIe-3620 front panel in the TX chassis to
the IF IN connector of the mmRH-3647 back panel using an SMA(m)-to-SMA(m)
cable.
