8.5.1 RUN 2
After the Run 1 is completed, the Run 2 begins automatically, carrying out
the measurements vs Lq limit, or, in other words, performing the heart of
the test itself.
Among the parameters, on the display it is reported the max clicks number
allowed (25% of the clicks measured during Step 1).
In certain conditions, the analyzer may judge the input attenuation is
not adequate (for example, when the limit is recalculated following up
the Lq value): in that case, a message appears, requiring additional
attenuation.
In most cases, it is enough to touch
OK to adjust the input attenuation to
the optimum value and continue the test.
The total amount of available internal attenuation is 45 dB but the
CA0010 is also equipped with supplementary attenuators so that a
very high dynamic range can be accomplished.
Please remember that the maximum input signal allowed is 7 V (137
dB
µ
V), and that a click test may result in a potentially dangerous
condition for the input stage of the receiver.
Before to apply an unknown signal to PMM ER8000 receiver, use an
oscilloscope or a wide band RF voltmeter to measure it.
If needed, set a proper threshold and consequently input attenuator.
8.5.2 Stop and Pause
If Stop has been selected during a measurement, the test can then be
aborted or it is possible to go immediately to the next step.
If Paused, the test can be resumed at any convenient time.
