Intermodulation Analyzer
The Intermodulation Analyzer block offers a real-time IP3 (TOI) measurement.
Left hand sinde Input:
- IQ
- Tx
The block offers a real-time TOI measurement. Simply select the Base Frequency (center), the dual tune spacing (Offset Frequency) and the RBW and the measurement can start.
If you use the internal Tx you also need to set the Signal Strength accordingly.
With the help of the Power Range you can adjust the overall dynamic.
Finally the Auto button helps you with an automatic adjustment of f1 and f2:
A typical mission if you would use the internal SPECTRAN V6 vector signal generator as an ditone signal source. In this case all the settings are done automatically. All you do is adjust the signal strength of the Tx:
A typical mission using an external signal source:
Both frequencies (f1 & f2) and the corresponding intermodulation will be shown within a graph with full scalable spectrum incl. Clear/Write and AVG trace.
Multiple reference traces can be added for perfect DUT verification and documentation.
The frequency, RBW, span, power and reference level are fully adjustable offering the perfect settings for any setup you might need, to get the highest possible dynamic range and sensitivity for the measurement.
The complete measurement incl. all reference traces can be saved as a measurement package for later analysis, documentation or data exchange.
A typical measurement with internal Tx:
The Intermodulation Analyzer now offers a full loaded trace feature.
You can now export and import traces or add copy's (reference traces) e.g. from different DUTs for a better single view comparison:
The Intermodulation Analyzer block now includes an IP5 measurement:
