How to Make an EVM (Error Vector Magnitude) Measurement

The EVM (Error Vector Magnitude) measurement is set up and is intended to be
used as a "one-button" measurement. After you have properly connected the
instrument to the digital communications system equipment and selected the EVM
measurement, the measurement is made using the default parameters defined by
the selected standard.
Even though the measurement is designed as one-button measurement, you may
change the default settings using various setup keys. However, changing the
default settings may produce measurement results that are outside of the
parameters of the selected standard.
Most measurements can be performed using the simple four-step procedure
outlined in the table below. Most measurements are performed using only the
primary keys listed in conjunction with a minimum of setup keys. Measurement
