QA402 User Manual

If the measured response is within the mask boundaries, you will see PASS displayed, and FAIL display if not.
Masks can be as complex as required to capture the expected behavior. You can create them manually, as
above, or use an automated measurement to export a mask.
Full Scale Input
Full Scale Input determines the maximum input before clipping will occur. Note that the maximum input to the
analyzer is +32 dBV, with a max DC of 40V and a max AC
PEAK
+ DC of +/- 56V. Those limits must always be
respected, even if you are on the +42 dBV input range. The concept of full-scale input is to help the engineer
understand how far away they are from clipping, as this has an impact on the measurement quality.
The full-scale input control group is shown below:
Note that for level 24 dBV and greater, the attenuator is active. The attenuator is a hardware divider at the
front-end of the analyzer that attenuates the reduces the signal by 24 dB. When the input attenuator is active,
