1. Auto
When the sweep mode is autod, the analyzer selects the sweep mode automatically between
Sweep and FFT Mode in the shortest time.
2. Sweep
Work in point-by-point scanning. The Sweep mode is only available when RBW is in 30 Hz – 1
MHz.
3. FFT
Work in FFT scanning. The FFT mode is only available when RBW is in 1 Hz - 30 kHz.
When TG is on, the sweep mode is forced to Sweep.
2.2.4.5 QPD Dwell Time
Dwell time is the measurement time at a single frequency. QPD detector gets its weighted
envelope response during dwell time. The longer dwell time is, the more sufficiently QPD detector
responses to a single frequency, the more accuracy the QPD detector envelope is.
