input fields etc. in a dialog.
2.1.7 Front Panel Connectors
The RF and AF connectors and various additional control interface connectors are loca-
ted on the front panel.
2.1.7.1
RF Connectors
The SNAP N-type connectors on the front panel are used as inputs and outputs for RF
signals.
They are labeled RF 1 OUT, RF 1 COM, RF 2 COM, RF 3 OUT, RF 3 COM and RF 4
COM (the RF 3 and 4 connectors are optional).
The impedance of all RF connectors is 50 Ω. The frequency ranges vary depending on
the installed hardware options; input and output level ranges depend on the firmware
applications (refer to the data sheet). The command reference sections state the maxi-
mum frequency ranges available with a fully equipped instrument (including optional
parts).
The connectors are assigned to firmware application instances, see
.
COM connector: Bidirectional connector for various power ranges depending on the firm-
ware application (refer to the data sheet). The two LEDs above the connector indicate
the connector state:
●
The upper LED is lit as long as the R&S CMW500 is ready to receive signals.
●
The lower LED is lit as long as it transmits an RF signal.
OUT connector: Output connector for high RF output powers depending on the firmware
application (refer to the data sheet). The upper LED is lit as long as the R&S CMW500
transmits an RF signal.
Maximum Input Levels
The maximum input levels at all bidirectional RF connectors according to the front panel
labeling or the data sheet must not be exceeded.
In addition, the maximum input voltages of other input connectors at the front and rear
panel must not be exceeded.
RF connectors may warm up very much when high RF power is fed in!
