2.1.3.8 Correction
Correct the amplitude in order to compensate for the gain or loss from external devices such as
Antenna and Cable. When using this function, you can view the correction data table and save or
load the current correction data. When amplitude correction is turn on, both the trace and related
measurement results will be corrected.
1. RF Input
Set the input impedance for voltage-to-power conversions. The default is 50Ω. To measure a 75Ω
device, you should use a 75Ω to 50Ω adapter to connect the analyzer with the system under test
and then set the input impedance to 75Ω.
2. Apply Correction
Enable or disable amplitude correction and the default are Off. The spectrum analyzer provides
four correction factors and you can edit them separately.
3. Edit Correction Factor
Table 2-10 Edit Correction table
Select the correction factor on or off.
Add a point into correction table.
Select a point to edit by point num.
Edit the frequency value for the current selected point.
Edit the amplitude value for the current selected point.
Delete the selected correction point.
Clear all data of the correction table.
Save or load correction data. You can save the current correction
data into or load correction data from a .COR file.
2.1.4 Auto Tune
Search for signals automatically throughout the full frequency range; adjust the frequency and
amplitude for optimum display effect of the signal to realize one-key signal search and auto setting
of parameters.
In the process of auto search, The “Auto Tune” is shown in the status bar on the screen until
the search is finished.
Some parameters such as the reference level, scale, input attenuation and maximum mixing
level may be changed during the auto search.
