3.10 Instrument Functions - Spectrogram Measurements
Equipped with the firmware option R&S FSV-K14, the R&S FSVA/FSV provides a
graphical overview of changes in frequency and amplitude over a specified period of
time.
Not all measurement types available in spectrum mode can be displayed in the "Spec-
trogram" result display. If the "Spectrogram Measurement" option is active and a mea-
surement cannot be displayed in form of a spectrogram, the softkey of the correspond-
ing measurement is disabled.
All settings of the base unit are also valid for the spectrogram view and vice versa.
The following chapter describes the instrument functions specific to "Spectrogram"
measurements.
To open the Spectrogram view
The "Spectrogram" result display and its softkey menu is part of the "Trace" menu of
the base unit.
1. Press the TRACE key.
2. Press the "Spectrogram" softkey.
The menu for the "Spectrogram" result display opens.
Menus and Softkeys
The main menu for the "Spectrogram" result display is part of the "Trace" menu of the
base unit and is described in Chapter 3.10.2, "Softkeys of the Spectrogram Menu",
on page 555.
Furthermore, some special "Spectrogram" functions are included in the "Sweep" menu,
see Chapter 3.2.7.1, "Softkeys of the Sweep Menu", on page 246.
The "ASCII Trace Export" softkey stores the data for all frames in the history buffer of
the spectrogram to a file. See Chapter 3.10.4, "ASCII File Export Format for Spectro-
grams", on page 561 for details.
Marker functions
The functions in the "Marker" menu (MKR key) are the same as for the base unit (see
Chapter 3.3.1.1, "Softkeys of the Marker Menu", on page 280). However, note the
slightly different behavior as described in Chapter 3.10.1, "General Information",
on page 552.
