Physical Description
The SC5310A is a serial controlled core module with all user connections on the front face of the
module.
Signal Connections
All signal connections (ports) on the device are female 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. Connections that are improperly mated, dirty, damaged, or worn 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 degrade
measurement performance until fully evaporated (this may take several days).
Tighten all SMA connections to 8.8 in-lb max (100 N-cm max)
RF In
This is the RF input port to the device with nominal impedance of 50
. Its
maximum input power is +27 dBm.
IF2 In
This is the input to the second IF stage of the converter. Its nominal input
frequency is 1250 MHz.
IF Out
This is the IF output of the device with nominal impedance of 50
.
Ref In
This is the 10 MHz refence input to the device, enabling the device to phase
lock its internal clocks to an external reference source. This nominally 50
port is AC coupled. Maximum rated input power is +10 dBm.
