GSP-830 User Manual 52 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.
