![]() Many of the SDG products have a wave combine feature that mathematically adds the waveforms for both channel 1 and channel 2. The ARRL and other radio-centric organizations have lots of data on testing receivers, for those so inclined. You can use two-tone signals to check the performance of RF receivers. NOTE: Two-tone testing is commonly used to test the performance of audio data that is embedded in modulated signals like AM or FM radio broadcasts. You can download it here: EasyWaveĮasyWave has an interesting feature called Equation Draw that enables you to create complex waveforms using some common basic math and trigonometric functions, like +, -, *, /, sine, cosine, and more. We will then show how to use this signal to modulate a carrier up-to 500 MHz using the other SDG output channel.ĮasyWave is free software designed to help create and edit arbitrary waveforms and download them to applicable SIGLENT SDG series of arbitrary waveform generators, including the SDG800, 1000, and X series. ![]() In this note, we are going to use Equation Draw within EasyWave to create a waveform that is built using the addition of sine waves with two different frequencies (7 Hz).
