The minimum Dwell Time is coupled to the detector type:-
a) When the Quasi Peak detector is selected, the minimum Dwell Time is 0.5 ms.
b) When the EMI Average/ RMS Average detector is selected, the minimum Dwell Time is 0.1 ms.
c) When the Peak/ Negative Peak detector is selected, the minimum Dwell Time is depends on the
smallest RBW among ranges turned on in the Scan Table.
RBW≤ 10 Hz 10 ms
10 Hz< RBW< 100 Hz 1 ms
100 Hz< RBW< 200 Hz 1 ms
200 Hz < RBW<1 kHz 0.1 ms
1 kHz < RBW<100 kHz 0.1 ms
≥100 kHz 50 us
Dependencies This key is grayed out during final measurement. If the grayed out key is pressed, an advisory
message is generated. If the equivalent SCPI command is sent, this same message is generated as
part of a “–221, Settings conflict” warning.
Couplings If “Off” is selected for detector 1, this key is grayed out and shows 200 ms.
