Analyze correlations between WLAN and Bluetooth

Question

My mobile device includes multiple communications systems such as WLAN and

Bluetooth. Is it possible to analyze correlations between these systems with only

one U37xx spectrum analyzer?

Answer

Yes, it is. Option 10 provides you with a two-channel input for the U37xx.

Moreover, you can add the time-domain analysis option 56.

Option 56 makes it possible to analyze a phenomenon that could not be

measured in a short time with conventional spectrum analyzers. E.g. you can

view the measurement data as Time vs Frequency, Time vs Amplitude, Time vs

Phase or FFT spectrum.

If your mobile device includes multiple communications systems such as WLAN and

Bluetooth, options 55 and 56 provide a maximum measurement bandwidth of 40 MHz.

If you install option 56 for two-channel operation, you can analyze correlations

between the individual systems on the combined modules, such as transmitting timing

and interference. The results are displayed at the same time on only

one U37xx analyzer.
