Description Specifications Supplemental Information
EMI Average Detector Used for CISPR-compliant average
measurements and, with 1 MHz
RBW, for frequencies above 1 GHz
Default Average Type All filtering is done on the linear
(voltage) scale even when the display
scale is log.
Quasi-Peak Detector Used with CISPR-compliant RBWs,
for frequencies ≤ 1 GHz
Absolute Amplitude Accuracy for
reference spectral intensities
Meets CISPR standards
