Amplitude Correction 

Overview 

 

Background 

Amplitude correction adjusts the GSP-830’s frequency 
response by changing amplitudes for specific frequencies.

Range Correction 

set 

5 sets, 30 correction points each 

 Amplitude 

−40 to +40dB per correction point, 
0.1dB resolution 

 Frequency 

9kHz to 3GHz, 1kHz resolution 

Icon 

 

The amplitude icon appears at the bottom of  
the display when amplitude correction is on. 

Correct amplitude step by step 

 

Example 
description 

In this example, the network between the GSP-830 and 
DUT distorts the waveform and pushes the amplitude 
down at around 2.4GHz. Amplitude correction can bring 
the amplitude back to its original level. 

Correction level 

In this example the amplitude around 2.4GHz is boosted 
by +1 to +3dB as shown below. 

 2.2GHz 

+2.5dB 

 2.3GHz 

+1.3dB 

 2.4GHz 

+2.8dB 

 2.5GHz 

+2.5dB 

 2.6GHz 

+1.2dB 

Waveform (before 
correction) 

The frequency response is distorted (non-flat) and the 
level is attenuated by 2 to 3dB.
