Spectrum Analyzer Mode
The analyzer mode is activated by pressing hotkey SPECTRUM (see also Section 'Mode Selection')
SPECTRUM
The SPECTRUM hotkey selects the ANALYZER mode.
This mode is the default setting of the R&S ESCI.
The functions provided correspond to those of a
conventional spectrum analyzer. The analyzer measures
the frequency spectrum of the test signal over the
selected frequency range with the selected resolution and
sweep time, or, for a fixed frequency, displays the
waveform of the video signal.
Note: If two displays (screen A and screen B) are opened after switch-on of signal analysis, the
analyzer mode is only set for the display activated for entry (marked at the top right corner of
diagram). For the other display, the previous settings remain valid.
Data acquisition and display of measured values is sequential: first in the upper and then in the
lower display.
