Setting the value of the shift of the input signal frequency
Freq. shift
, is made by entering a numerical
value in the submenu that opens, as in figure 24. Enter the numerical value of the frequency and press
Enter
. To delete erroneous or previously entered values, press
Del
. To refuse to enter a value, click
Cancel.
7.9.5. When using external attenuators or amplifiers, to correctly indicate the amplitude of the input
signal, enter the value of the scale shift
Amp. shift
to dB as shown in Figure 25.
igure 25 Entering the value of the scale shift in amplitude
Setting the scale value of the input signal amplitude
Amp. shift
, produces both positive and negative
numeric values in dB, in the submenu that opens, as shown in figure 25. Enter the numerical value of the
attenuation and press
Enter
. To delete erroneous or previously entered values, press
Del
. To refuse to
enter a value, click
Cancel
.
Note. Depending on the device that converts the signal before the receiver enters the device, the nu-
merical value of attenuation can be entered both positively and negatively (for convenience of displaying
the real signal graph, on the instrument's logarithmic grid.).
7.9.6. If necessary, set the
Idle shutdown
auto-shutdown timer in the range of 3 to 15 minutes from
the time of inactivity. This setting allows you to significantly save battery power. If there is no need to turn
off the device after a certain period of inactivity, select the parameter
never
. Setting the idle time of the
device until the automatic shutdown
is performed by “scrolling” the values to a fixed selected area.
7.9.7. To enter the main menu, press the button (14)
«MENU»
.
7.10.
Custom settings menu
7.10.1. To save the spectrum scan settings (frequency range, attenuator value), settings for equip-
ment testing (frequency and power of the internal signal generator), etc., enter the main menu by press-
ing the
«MENU»
button (14) (Figure 6) and select subsection
Presets
. A menu of custom settings will
appear on the screen, as in figure 26.
