Description
The Amplifier high frequency peaking is adjusted that the bandwidth is adequate
and that the aberrations are not excessive. The Standard requires the use
an 11402 mainframe to assure that the plug-in properly in any
mainframe. If an 11402 mainframe is not available, use an 11401 to perform this
procedure. If neither
nor mainframe is available, then use the
Alternative Procedure
at
the end of this part.
First, the Signal Standardizer provides a reference waveform to characterize the
mainframe. Mainframe aberrations are displayed at 2% per division.
the waveform is compared with the characterizations of the waveform in the
Examine Mainframe Step Response section to determine the plug-in’s contribution.
I
Measurement Limits The difference between the two waveform aberrations should not exceed 4.5% peak
(2.25 divisions) and 7% (3.5 divisions) peak-to-peak. One major division
= 2%.
