To View a Two–Tone Waveform
This procedure describes how to configure the spectrum analyzer to view a
two–tone waveform and its IMD products. Actual key presses will vary,
depending on the model of spectrum analyzer you are using.
1. Preset the spectrum analyzer.
2. Set the carrier frequency to 20 GHz.
3. Set the frequency span to 60 MHz.
4. Set the amplitude for a 10 dB scale with a 4 dBm reference.
5. Adjust the resolution bandwidth to sufficiently reduce the noise floor to
6. Turn on the peak detector.
7. Set the attenuation to 14 dB, so you're not overdriving the input mixer on
You should now see a two–tone waveform with a 20 GHz center carrier
frequency that is similar to the one shown in
products at 10 MHz intervals above and below the generated tones, and a
carrier feedthrough spike at the center frequency with carrier feedthrough
distortion products at 10 MHz intervals above and below the center carrier
frequency.
