Performing a Linktest

. The test results are displayed.
<var>
Symbol variation within the configured accuracy. The default is 16,
meaning the symbol changes every 781 frames, the equivalent of 1E6 bits.
A higher var value results in a slower test with more reliable BER
statistics.
Linktest takes only multiples of 16. For example, if <var> is set to 32, the
symbol changes every 390 frames. If it is set to 30, it still changes every
390 frames.
If <var> is set to 16, and <acc> is set to 7, then the symbol will change
every 7,810 frames.
<pps>
Transmission speed in packets per second. The default is 60 packets per
second. A low pps value means the Linktest decreases the proportion of
test data to message data. A high pps value means that Linktest increases
the proportion of test data to message data.
