Power calibration: An external generator can provide the reference signal for a source or receiver
calibration. A typical example is a receiver power calibration using a measured wave b
1
.
Configured external generators can be selected as additional sources in the More Wave Quantities, More
Ratios, Port Configuration, and in the power calibration dialogs.
To control external generators via LAN or GPIB interface, it is necessary to install the Virtual
Instrument Software Architecture (VISA) library on the network analyzer. VISA provides the programming
interface between the hardware and the analyzer's application environment.
A suitable VISA library is available from Rohde & Schwarz, see Introduction to Remote Control. Use the
USB-to-IEC/IEEE Adapter (option R&S ZVAB-B44) to control devices equipped with a GPIB interface.
