Description
5 Measurement parameters
Shows the basic measurement parameters (level and frequency offset; numerically and
bar graph). The squelch level is also shown by means of an indicating marker in the bar
graph.
6 Panel area
The panel area is used for displaying the various panels of the R&S EB500 (spectrum
and waterfall are shown).
●
The light cyan color of the scale bar indicates that the panel is in focus: softkey
operations affect the panel (see below). A marker to show the squelch level relative
to the trace level is also displayed.
●
The dark blue bar around the demodulation frequency marking denotes the band-
width being demodulated.
●
On the right side, the rainbow colored bar indicates the color that is mapped to the
corresponding spectrum level for the waterfall display.
7 Softkeys
Softkeys change their function based on the panel that is in focus. They show panel-
dependent parameters, e.g. "SPAN" and "STEP" for IF panel and IF Waterfall panel.
Other softkeys are only related to e.g. RF panel, RF Waterfall panel etc.
Softkeys can be related to hardkeys: they can e.g. provide selection options in case one
of the Utility keys is pressed or in case DET or MARK is pressed.
Softkeys can also provide the option for selecting a unit (kHz, MHz etc) e.g. when keying-
in a frequency, they can provide additional functionality when editing input fields in dia-
logs, e.g. backspace or caps lock. Finally they can serve as shortcut keys for navigating
through tables in dialogs, e.g. in the "Memory Setup" dialog or through the "Help" pages.
2.3.2
Turning on the R&S EB500 for the First Time
Upon power on, the R&S EB500 is always defaulted into the Fixed Frequency
Receiver Mode (reference to Operating Manual). In this mode, the R&S EB500
behaves as a normal receiver with the screen as shown in
​
chapter 2.3.1, "GUI
Layout" , on page 19. Upon power on the speaker will always be muted.
2.3.2.1 Unmute the speaker
The volume of the speaker and headphones is adjusted with the
VOLUME KNOB. Pressing the knob will mute / unmute the speaker.
Headphones remain active when the speaker is in mute position.
