SFC1800A Synthesized Frequency Upconverter Rear Panel Interfaces
TM111 – Rev. 1.0 5-7
5.12.1 IF Monitor Port
The IF Monitor Port is an SMA-F Type Connector located on the front panel that allows
monitoring of the upconverter's IF Output. The power level of the monitored signal will be-15 dB
nominal below the level present at J2.
5.12.2 RF Monitor Port
The RF Monitor port is an SMA-F Type Connector located on the front panel that allows
monitoring of the upconverter's RF Input. The power level of the monitored signal will be-15 dB
nominal below the level present at J1.
5.13 Optional Chain Switching Module
5.13.1 (J10)
J10 is an SMA-F Type Connector. When connected to J1 in the chain switching configuration, it
provides a direct path for the RF Input through the switch module for non-faulted conditions.
5.13.2 (J11)
J11 is an SMA-F Type Connector. It is the RF Input of the SFC1800A Upconverter in the chain
switching configuration.
5.13.3 (J12 and J13)
J12 and J13 are SMA-F Type Connectors that provides an RF signal path from the backup
converter to each converter in the redundancy chain in a non-fault condition. During a fault
condition, the faulted converter changes the flow from J13 to J12 to J13 to J11.
5.13.4 (J14)
J14 is a BNC Female Connector. It is connected to the Converter IF Output (J2). In a non-
faulted condition, the through path of the switch module is from J14 to J15.
5.13.5 (J16 and J17)
J16 and J17 are BNC Female Connectors that provide an IF signal path from the backup
converter to each primary converter in the converter chain. In a faulted condition, the switch will
change the IF flow from the backup converter to the IF Output (J15).
