7.4.4. The level of attenuation of the input signal (the value of the internal attenuator) is set automati-
cally, depending on the set value
Reference amplitude
.
Attention!
If the input signal level is much higher than the
Reference amplitude
value, a warning
message
Dynamic range exceeded
appears on the device screen. In this case, the correct display of
the input signal level is impossible. In this case it is necessary:
- increase the value
Reference amplitude
(the internal attenuator will be activated);
- to use an external attenuator.
7.4.5. To exit to the main menu, press the button (14)
«MENU».
7.5. Menu for setting markers and signal peaks
7.5.1. To enter the menu of setting markers and peaks, enter the main menu of the device (Figure 6)
by pressing the button (14)
«MENU»
. Select subsection
Markers and Tracing
. The menu appears on the
instrument screen, as in Figure 10.
Note. To quickly access the menu, press and hold the button for about 2 seconds (13)
«MKR»
.
igure 10 The menu of markers and peak values of the signal
7.5.2. In this menu are installed:
Trace maximum
– when this mode is enabled, the maximum values of the signal are displayed on the
screen and a spectrogram of red color is built on the points of the maximum values.
Trace minimum
– when this mode is activated, the minimum signal values are displayed on the
screen and the spectrogram is constructed in green, by points of minimum values.
The simultaneous use of the modes of maximum
Trace maximum
and minimum
Trace minimum
display of points allows determining the maximum dynamic range of the signal under study.
Turning on / off the
Trace maximum
and
Trace minimum
modes is performed by moving the “slider”
to the right / left opposite the corresponding mode.
Marker
- visual indicator of signal amplitude at the frequency of marker location specified by the opera-
tor. The design of the device allows the use of up to four multi-colored markers at the same time to moni-
tor the change in the amplitudes of the analyzed signal at four frequencies given by the operator.
Note. Also, the marker can be switched to the maximum signal tracking mode (
Peak
mode). Up to four
simultaneous tracking peaks on a chart.
7.5.3. Setting the specified marker frequency is performed by entering a numeric value in the opened
submenu, as in figure 10. Enter a numeric frequency value and press
Enter (enter data)
. To delete erro-
neous or previously entered values, press
Del (Delete)
. To refuse to enter a value, click
Cancel
. In our
example, in figure 11, we set the frequency to 3600 MHz for marker 2.
