NI 5600 Front Panel

This sections describe the connectors and LED indicators on the hardware front panel of the NI 5600 RF downconverter module. All inputs and outputs are AC-coupled.

ConnectorUse
FREQ REF IN Routes an external frequency reference signal to which the NI 5600 can lock. This signal can be propagated to the PXI backplane when the NI 5600 is installed in PXI Slot 2.
10 MHz OUT Connect the lower 10 MHz OUT connector to the REF CLK IN connector on the NI 5620 module front panel. Both connectors output replications of the downconverter 10 MHz frequency reference signal, useful for driving other devices. Each replication is 180 degrees out-of-phase with the other. The signal output at these connectors is always on and cannot be disabled.
10 MHz OUT
PXI 10 MHz I/O Bidirectional connection to the PXI 10 MHz backplane clock.

This connector can be used to drive the PXI 10 MHz backplane clock only when the NI 5600 downconverter module is installed in PXI Slot 2. To drive the PXI backplane with the NI 5600 onboard frequency reference, connect the PXI 10 MHz I/O connector to the 10 MHz OUT connector on the NI 5600 RF downconverter module front panel as shown in Interconnected NI 5600 Front Panels. Refer to the ni5660 Configure Reference Clock VI for more information.

This connector can be used to export the PXI 10 MHz backplane clock when the NI 5600 downconverter is installed in any PXI slot.
OUTPUT Connect to the INPUT connector on the NI 5620 digitizer module front panel.

Outputs the frequency-translated IF signal for digitization.
INPUT Connect to the analog RF input signal to be measured by the RF Vector Signal Analyzer.



The following table provides LED and indications information for the NI 5600 RF upconverter module front panel LEDs:

LED Indications
POWER Indicates the basic hardware power status of the NI 5600 downconverter module. This LED functions identically to the ACCESS LED on the digitizer module front panel.
  • OFF—The module is not yet functional, or has detected a problem with a PXI power rail.
  • GREEN—The module is functional and receiving power.
STATUS Indicates the status of the NI 5600 downconverter module PLLs.
  • OFF—The module is in an uninitialized state, or the module PLLs are attempting to lock.
  • GREEN—The module is in a ready state; applicable PLLs are locked.

Note  Refer to the NI 5660 RF Vector Signal Analyzer Specifications document included in the NI 5660 RF Signal Analyzer kit for more information on NI 5600 connectors.
