Power Connection; Signal Connections - SIGNALCORE SC5312A User Manual

The SC5313A is a core module-based IQ demodulator with all I/O connections and indicators located on
the front face of the module as shown below.

Power Connection

Power to the SC5313A is provided to the device through a two-position screw terminal block connection.
Proper operation of the device requires a +12 VDC source and ground return wires capable of delivering a
minimum current of 1.5 amps. The polarity of the connector is shown on the front panel of the RF
module, just above the screw terminal block.

Signal Connections

All signal connections (ports) on the device are SMA-type. Exercise caution when fastening cables to the
signal connections. Over-tightening any connection can cause permanent damage to the device.
The condition of your system signal connections can significantly affect measurement accuracy and
repeatability. Improperly mated connections or dirty, damaged, or worn connectors can degrade
measurement performance. Clean out any loose, dry debris from connectors with clean, low-
pressure air (available in spray cans from office supply stores).
If deeper cleaning is necessary, use lint-free swabs and isopropyl alcohol to gently clean inside the
connector barrel and the external threads. Do not mate connectors until the alcohol has completely
evaporated. Excess liquid alcohol trapped inside the connector may take several days to fully
evaporate and may degrade measurement performance until fully evaporated.
Tighten all SMA connections with 3 in-lb min to 5 in-lb max (56 N-cm max)
LO Out This port outputs the tunable LO signal allowing phase-
coherent daisy-chaining of multiple IQ demodulator modules.
The connector is SMA female. The nominal output impedance
is 50 .
RF In This port accepts an RF signal ranging from 400 MHz to 6 GHz.
The connector is SMA female. The nominal input impedance is
50 . Maximum input power is +23 dBm with ATTEN#1 set to
at least 10 dB attenuation.
