Signal Connections - SIGNALCORE SC5510B Operating & Programming Manual

4. Signal Connections

All signal connections (ports) on the SC5510B/11B are SMA-type. Exercise caution when fastening cables
to the signal connections. Over-tightening any connection can cause permanent damage to the device.
RF OUT This port outputs the tunable RF signal from channel 1 of the source. The
CHANNEL 1 connector is SMA female. The nominal output impedance is 50 Ω.
RF OUT This port outputs the tunable RF signal from channel 2 of the source. The
CHANNEL 2 connector is SMA female. The nominal output impedance is 50 Ω.
REF OUT This port outputs the internal 10 MHz reference clock. The connector is SMA
female. This port is AC-coupled with a nominal output impedance of 50 Ω.
REF IN This port accepts an external 10 MHz reference signal, allowing an external
source to synchronize the internal reference clock. The connector is SMA
female. This port is AC-coupled with a nominal input impedance of 50 Ω.
Maximum input power is +13 dBm.
The condition of your system's 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.
