HIGHLIGHTS

  • Internal sources provide fast swept-IMD measurements, typically more than 100 times faster than the traditional spectrum-analyzer-based approach
  • An easy test set up with built-in signal combiner (available with PNA-X), two internal sources, and a simple user interface
  • Internal calibration routine for improved accuracy
  • Spectrum-display mode eliminates the need for a spectrum analyzer for troubleshooting

The S93087B intermodulation distortion (IMD) application makes it very easy to set up and calibrate swept-IMD measurements of both amplifiers and frequency converters. It controls the frequency and power of internal and external sources and tunes the receivers at main tones as well as IMD tones in the single measurement channel. The user can sweep either the center frequency of the two stimulus signals, the frequency spacing of the two stimulus signals about a fixed center frequency, or the power of one or both stimulus signals or the power of the LO signal. The analyzer can measure intermodulation distortion products of order 2, 3, 5, 7, or 9, and can display the associated intercept points. Besides, an IM Spectrum mode gives a spectrum-analyzer-like display for confirming or trouble-shooting measurements. Not available with PNA Option 200, 210, and 400. S93087B is equivalent to Option 087 on PNA/PNA-X Series A model network analyzers.
