Measurement
Click on the [Ch Quality] button to open the Channel Quality Measurement menu.
Procedure
It is important to determine the quality of the channel IC, any non-linear distortions in
the channel will degrade the error rate performance of the system. When channel
quality measurement is performed, it executes the measurement sequence for one cycle
only, i.e., there is no average measurement for channel quality.

VEE Measurement Program Operation
Executes the optimization of the parameters
set at [Optimize] menu for optimum
measurement results. Optimization is required
whenever you change the 'User Data Rate'
and 'Endec' parameters.
Specifies the number of data bits to be
recorded on the media per second. A user data
is supplied to the encoder, after encoding this
user data is transformed into a channel data.
The channel data is the actual data written on
the media. A channel data rate on the other
hand, defines how many encoded bits are
written on the media per second, i.e. after
encoding. The range should be from 50Mbit/s
to 800 Mbit/s. Refer to the
"hpe5022_BER_userDataBitRate" function of
the programming manual for details.
