When the extension unit is connected to the network analyzer via the type B USB con-
nector on the rear panel of the extension unit, the USB connectors on the front and rear
panel of the extension unit are functionally equivalent to those of the network analyzer.
For the USB connection between the two instruments, see also
The length of the connecting USB cables should not exceed 1 m. The maximum current
per USB port is 500 mA.
2.1.3 RF Connectors
The extension unit provides three groups of RF connectors that are located in color-coded
areas on the front panel. The colors indicate the corresponding network analyzer ports
that are modified in their functionality.
An RF connection to any of the network analyzer ports requires option R&S ZVA24-B16,
"Direct Generator/Receiver Access" on the analyzer side.
RF emissions
To comply with the emission requirements, always use semirigid cables (preferably, the
cables supplied by Rohde & Schwarz) to connect the extension unit to the network ana-
lyzer. Use double-shielded measurement cables for connections to the 3.5 mm test port
connectors PORT 1 and PORT 2 and the MONITOR output.
2.1.3.1
RF Connectors Port 1
The Port 1 connectors allow components inside the extension unit to be looped into the
RF signal path of the network analyzer (NWA) test port 1. The connectors must be con-
nected to the corresponding connectors provided by the NWA option R&S ZVA24-B16
(see
chapter 2.1.3.4, "Rules for RF Connections"
The following connectors are available:
●
Two 2.92 mm connectors SOURCE IN and SOURCE OUT. To modify the source
signal from analyzer port 1, connect the 2.92 mm connectors as follows:
