150 kHz Highpass
Enables or disables the use of an additional 150 kHz highpass filter to protect the
R&S FSV/A LISN from excessive input.
The filter is available for the ENV 216 network only.

5.13.5 EMI result analysis
The EMI measurement provides functionality to analyze the results.
Marker demodulation
The R&S FSV/A is able to demodulate AM and FM signals for acoustic tests and moni-
toring purposes.
When the demodulator function is active, the EMI measurement demodulates the sig-
nal continuously (regardless of the "Continuous Demodulation" setting in the marker
function configuration). The demodulation begins as soon as a marker is activated.
During the initial measurement, demodulation is performed for the entire measurement
span; during the final measurement only the detected peak marker positions are
demodulated (for the defined dwell time). You can listen to the results during the mea-
surement using headphones or the internal speaker.
This feature requires the optional audio demodulator (R&S FSV3-B3).
For more information, see Chapter 7.3.4.7, "Demodulating marker values and providing
audio output (marker demodulation)" , on page 547.
Limit lines
General limit line functionality is provided by the R&S FSV/A base unit. The base unit
also provides various predefined limit lines that you can use for various applications.
The EMI measurement adds further predefined limit lines designed in compliance with
several EMC standards.
Limit line configuration is described in Chapter 7.4.2.2, "Limit line settings and func-
tions" , on page 565.
Test reports
The R&S FSV/A features a test report generator. A test report is a document that sum-
marizes the results and configuration of measurements.
Test reports are based on a general template, and are completed with user-defined,
measurement-specific contents. You can create multiple templates for different applica-
tions.
Test reports are described in Chapter 9.6, "Working with test reports" , on page 668.
