Phase Matrix PXI-1430B RF Downconverter Module
Quick Start Guide
RF B IN 100 kHz to 2.9 GHz
SMA (f) connector is used to input
an RF signal that is to be downconverted.
This RF signal can be supplied one of two ways:
•
directly to the RF B IN connector, in a range of 100 kHz to 2.9 GHz.
The maximum operating power applied to the PXI-1430B’s input
connector (RF B IN 100 kHz to 2.9 GHz) is -40 dBm!
The PXI-1430B is designed to operate with signals below -40 dBm.
Operation above -40 dBm is allowed with degraded performance.
•
(attenuated) through the PXI-1410 Preselector Module’s RF B IN
connector, out of its RF B OUT connector, and in through the
RF B IN connector of the PXI-1430B RF Downconverter Module.
LO B IN
SMA (f) connector is used to deliver the LO signal from the
PXI-1450B Local Oscillator Module, into the front panel of the
PXI-1430B RF Downconverter Module.
This LO signal is used to down convert the RF signal that is input to the
RF B IN connector and produce a 250 MHz IF OUT; see the description
for the IF B OUT connector.
REF B IN 100 MHz
SMB (m) connector is used to deliver a 100 MHz
reference signal into the front panel.
This 100 MHz reference signal can be supplied by the PXI-1450B
Local Oscillator Module from either the REF A OUT 100 MHz or
REF B OUT 100 MHz. These 100 MHz reference signals are
phase-coherent with the 10 MHz reference being used.
VIDEO OUT
SMB (m) connector is used to output the video output
signal which is enabled at all times. The video output is a DC level
which is representative of the total signal power contained within the
IF passband of the system.
C A U T I O N
The maximum power output of the IF B OUT connector can 20 dBm!
Care should be used when connecting this IF B OUT to a digitizer or other equipment.
When the IF B OUT normal operating range is exceeded, the overload indicator will be
illuminated. (Refer to
