Subsequent tests would focus more on noise measurements, IMD, and other parameters at a typical
listening level.
Finally, “switchover” in the table below refers to the time it takes an operator to remove the amplifier
that was just tested and replace it with another amplifier. The 20 second figure used in the table below
suggests a very fast switchover operation, most likely automated and extremely high volume. The test
flow below suggests a 15 hour (2-shift) production of 1200 amplifiers tested per day per test bay.
Impact of Switchover
The impact of switchover time is significant in the average power calculation. If the switchover time is 2
minutes, due in part to an operator managing several bays and a fully manual switchover, then the
average power drops to 1.5W.
In summary, you need to plan your thermal budget ahead of time to ensure the QA450 can meet your
needs. Hitting the thermal targets above will ensure continuous operation without having to wait for
cooldowns.
Because the QA450 can also report the temperature to other applications via the REST web interface,
it’s also possible to
program your test flow to wait for the temperature to fall below a threshold before
you begin testing a new amplifier.
