EMI Measurements Mode Settings

EMI Measurements Mode Settings
This section contains content unique to EMI measurements mode and some
features that are similar to SA mode settings. Unique Option 361 EMI
measurements content can be found in this chapter. But, when EMI/SA mode's
shared feature content is referenced, you are referred to
(Spectrum Analyzer) Mode (Option 233–Mixed Analyzers)."

Interference) Control" on page
When you initially select EMI, I/Q Analyzer, Real-time SA, or some of the
other spectrum settings (such as center frequency) a factory channel
Equalization measurement is applied to the signal. During a channel
equalization measurement, the FieldFox displays a "Start Channel
Equalization". Stopping channel equalization is not permitted. See also,
"Alignments" on page
(Option 233–Mixed Analyzers)."
Frequency Range
The X-axis frequency range determines the frequencies that are measured for
each sweep. The default Start and stop frequencies are dependent on the
CISPR band selected.
Although the start frequency can be set as low as -100 MHz, amplitude
accuracy is specified above 9 kHz (depending on your model). Below
9 kHz (depending on model), frequency accuracy is maintained, but
amplitude accuracy is degraded. Refer to
https://www.keysight.com/us/en/assets/7018-06516/data-sheets/5992-
3702.pdf.
The frequency range of the measurement can be changed using the following
methods:
— Set Center and Span frequencies (Frequency Span varies with instrument
— Set Start and Stop frequencies
— Using Marker > Center
