Option SD/HD Detailed Measurement Information
For a high-level procedure on how to take a measurement, refer to page 2 -23.
For a high-level overview of all the measurements, refer to the table beginning
on page 3 -16.
The following information applies to all the measurements.
Matrix Signals and Line Numbers
The matrix signals that are included with the Signal Source Set (refer to
page E -1) provide appropriate signals for all the measurements. Refer to the
Readme.txt files on the Signal Source Set for extensive information about the
files provided.
Averaging
The higher the average, the lower the variance of the measurement in the
presence of noise or other transient signal components. Set the average higher if
you would like to reduce the fluctuations in the measurement results.
The instrument averages results, not input waveforms. (If, on the other hand, the
Noise waveforms were averaged instead of the Noise results, the noise results
would appear lower than they should. Because of the instrument average results,
this problem is avoided.)
