Measurement wizard 
Guides the user through a sequence of individual measurements. Uses the R&S

Instrument View PC software to configure the 
measurement sequence including hints displayed on the screen. R&S
®
Instrument View is also used to combine the measurement 
results into user-configurable reports.
