In certain conditions the analyzer may judge the input attenuation is not
adequate: in that case a screen like the following appears and requires
additional attenuation.
It's enough to touch OK to adjust the input attenuation to the optimum value
and continue the test.
Please remember that the maximum input signal is 1 V (120 dBµV),
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 9010 receiver, use an
oscilloscope or a wide band RF voltmeter to measure it.
If needed, add a coaxial attenuator to the input signal line (a 20dB
external attenuator is always provided with PMM 9010-Click Option).
9.3.1 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.
