The V/A Ratio is only calculated and displayed for the primary
audio carrier, although both are compared to the criteria for pass/
fail analysis.

Tabular measurement information is displayed next to the bar
graphs. Measurements within the programmed Pass/Fail Limits
criteria are displayed in black text in a white box. Measurement
results outside of the limits criteria are displayed in red text to
indicate a failing result.

Channel – The channel number and modulation type are
displayed. The modulation display indicates the type of
modulation on the channel currently being measured, according
to the data in the Channel Table. It is important that the Channel
Table information is accurate. Erroneous measurement results
will be obtained if the wrong modulation type is set, since the
wrong detector type will be used for the measurements. An
average detector is used for digital measurements, while a peak
detector is used for analog carriers.

Video – Displays the video carrier frequency and the result of a
measurement of the video carrier peak level in dBmV.

Audio 1 – Displays the frequency of the audio carrier and the
result of the measurement of the primary audio carrier level in
dBmV.
result of the measurement of the primary audio carrier level in

Video to Audio Delta – This measurement will be added to a
future release of PC-IP software. Video to Audio Delta will be
the calculated difference between the video carrier level and the
primary audio carrier level in dB.
