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.
  • Page 99 SIGLENT At this time, the RF interface of the SSG3000X outputs a two-tone continuous wave signal with a carrier frequency of 1 GHz and an interval frequency of 1 MHz. The signal is used as the input of the active device, and the output signal is tested to obtain the OIP3 characteristic as shown in the following figure.
