Basically, a Multi-Scan measurement is a series of Pre-Scan measurements, one in every measuring position.
From these Pre-Scan measurements field plots similar to Scan measurements, are generated. So when viewing the result from a Multi-Scan measurement any frequency can be chosen to look at in detail.
- The spectrum analyzer is reset
- The Scanner moves to the first measuring position.
- Basic settings are transferred to the spectrum analyzer
- The spectrum analyzer is set to max hold mode.
(Max hold means that the highest amplitude at each frequency is kept.) - The spectrum analyzer takes a number of sweeps.
- The trace data is transferred to the software.
- Max hold mode is cleared.
- The Scanner moves to the next measuring position.
- Steps 4 to 8 are repeated until all measuring positions are measured.
- The Scanner moves to its starting position.
