AV
In the 2651, QP detection and AV detection are added for EMI measurement.
POS (Positive Peak)
SMPL (Sample)
NEG (Negative Peak)
QP (Quasi Peak)
AV (Average)
: The spectrum of the maximum value between the sample points
: The spectrum of the momentary value between the sample points
: The spectrum of the minimum value between the sample points
: The spectrum of the quasi peak value between the sample points
: The spectrum of the average value between the sample points
As for QP detection, the following characteristics are chosen according to RBW settings.

Preset (Initialization) (Refer to “18. Save / Load”)
In the 2651, the radiated emission measurement and the conducted emission measurement are added to the
preset as a default setting.
By pushing

NORMAL : The initial parameters of normal mode are set.
EMI-C : The initial parameters of conducted emission measurement are set.
EMI-R : The initial parameters of radiated emission measurement are set
In the radiated mission measurement, “USER” is selected as an antenna.
It is necessary to input the compensation data of antenna beforehand.
