Interconnection of Devices with Included NI 5660 Cables
Note
The published specifications document for your NI 5660 RF vector signal analyzer assumes
use of the included cables. Substituting different cables may affect performance.
1.
Using the short semi-rigid coaxial cable, connect the OUTPUT connector on the NI 5600 RF
downconverter front panel to the INPUT connector on the NI 5620 IF digitizer front panel.
Note
The semi-rigid cables must be installed so the bends point upwards, as shown in Figure 3.
2.
Using the long semi-rigid coaxial cable, connect the lower of the two 10 MHz OUT connectors on
the NI 5600 front panel to the REF CLK IN connector on the NI 5620 front panel.
Note
The NI 5600 onboard frequency reference can drive the PXI backplane clock
only
if the
RF downconverter module is installed in PXI Slot 2. When the NI 5600 is installed in PXI Slot 2, you
can configure it to lock the PXI backplane clock to the highly accurate and stable NI 5600 onboard
oven-controlled crystal oscillator (OCXO). You can also lock the NI 5600 to an external frequency
