Learning Event 8: DATA ANALYZER, MODEL 7422
Figure 2-4.
Data Analyzer, Model 7422, Front Panel View.
The data analyzer is a solid-state unit used to measure distortion in
either start-stop or synchronous digital signals.
It is designed to
accept either neutral or polar signals.
The analyzer operates a signal
rates from 45.5 to 9,600 bauds. The analyzer compares the incoming signal
with a highly accurate and reliable clock in the analyzer, and displays
the percent distortion on a meter. In addition, the analyzer provides the
signal for oscilloscope display.
