Single sweep sets the VNA Master to make a single sweep and then wait for additional commands. The Continuous mode sweeps continuously. In the External mode, the sweep is set to Hold until an external signal triggers a sweep. This must be a TTL signal, and it will trigger a sweep on the rising edge (> 3 V). At the completion of an externally triggered sweep (or multiple sweeps if averaging is enabled), the instrument returns to Hold.

Select 10 Hz for the maximum dynamic range; select 100 kHz for the maximum speed. Sweep Averaging Press this soft key to set the number of sweeps to use for averaging. The minimum number is 1.

RF Pwr in Hold On Off Press this soft key to toggle On and Off the condition of the RF power transmitted from Port 1 and Port 2 when the instrument is put in Hold mode.
