2 Analog Demodulation Option R&S FSV–K7
Overview of firmware option R&S FSV–K7
This section contains all information required for operation of an R&S FSVA/FSV
equipped with Application Firmware R&S FSV–K7. It covers operation via menus and
the remote control commands for analog demodulation measurements.
This part of the documentation consists of the following chapters:
●
Chapter 2.1, "Instrument Functions Analog
the overall instrument functions and provides further information
●
Chapter 2.2.1, "Softkeys of the Analog Demodulation
all softkeys available in the "Analog Demod" menu. This chapter also presents the
remote control commands associated with each softkey function.
●
The following chapters describe the softkeys of the other keys for the Analog
Demodulation option.
●
Chapter 2.3, "Remote Commands of the Analog Demodulation (R&S
on page 81 describes all remote control commands defined for the analog
demodulation measurement.
This part of the documentation includes only functions of the Application Firmware
R&S FSV–K7. For all other descriptions, please refer to the description of the base
unit.
2.1 Instrument Functions Analog Demodulation
The digital signal processing in the R&S FSVA/FSV, used in the analyzer mode for digi-
tal IF filters, is also ideally suited for demodulating AM, FM, or PM signals. The firm-
ware option R&S FSV–K7 provides the necessary measurement functions.
The R&S FSVA/FSV is equipped with a demodulator that is capable of performing AM,
FM, and PM demodulation at a time. Additionally maximum, minimum and average or
current values can be obtained parallel over a selected number of measurements.
By sampling (digitization) already at the IF and digital down-conversion to the base-
band (I/Q), the demodulator achieves maximum accuracy and temperature stability.
There is no evidence of typical errors of an analog down-conversion and demodulation
like AM to FM conversion and vice versa, deviation error, frequency response or fre-
quency drift at DC coupling.
To open the Analog Demodulation menu
●
If the "Analog Demodulation" mode is not the active measurement mode, press the
[MODE] key and select the "Analog Demodulation" softkey.
●
If the "Analog Demodulation" mode is already active, press the [HOME] or
[MEAS ]key.
The "Analog Demod" menu is displayed (see
