3.5 Test the OIP3 of Active Devices with the
SSG3000X
OIP3 is a key indicator for evaluating the linearity of active devices. This can be tested
using the SSG3000X with the SDG6000X series of arbitrary waveform generators.
The following steps describe how to generate a two-tone continuous wave signal with a
carrier frequency of 1 GHz and an interval frequency of 1 MHz to test the OIP3 of the
active device.
1. Connect the output interface of the SDG6000X to the external modulation interface of
the SSG3000X;
2. Open the EasyIQ software, configure it as shown below, and download the Multitone
data to the SDG6000X;
3. Configure the SSG3000X and SDG6000X as shown below, then open the output of
the SDG6000X, the IQ, MOD and RF output of the SSG3000X;
