Making the Modulation Overview Measurement

Purpose

The modulation overview measurement allows you to measure and report several
modulation metrics on a burst of any type. This measurement measures and
displays:
• Initial Carrier Frequency Tolerance
• Hi Frequency Pattern ('1010') peak deviation
• Low Frequency Pattern (3 or more 1's or 0's) peak deviation
• The ratio Peak High Frequency Dev/ Peak Low Frequency Dev
The first 8 bits of the payload are also displayed which is useful for identifying the
different types of test signals (since they usually contain 8 bit repeating patterns).

Measurement Method

In order to perform these measurements to the Bluetooth™ specification, you
should run the individual measurements. They will show whether the results
passed or failed. This method provides results more quickly, without having to
change signal types (as in the modulation characteristics measurement). It is also
convenient for making adjustments in real-time.
