ous" sweep), where the measurement is continuously repeated without fixed time refer-
ence.
Any trigger event may start an entire sweep or a part of it. Moreover, it is possible to
switch off the RF source between consecutive triggered measurement sequences, and
to define a delay between trigger events and the measurement sequences.
The trigger settings are also valid for calibration sweeps. This means that, in external
trigger mode, the external trigger signal must be available during the system error cor-
rection, too. To start the calibration sweeps without delay, use the "FreeRun" trigger
type.
