Figure 10-31. How modulator intensal dynamic impedance interacts with load impeaizme to attenuate<br />
input voltage variations.<br />
Injectron beam-switch tube. The incremental above-the-knee impedance of the<br />
L-5097, for instance, is approximately 75,000 ohms, which is what has been illustrated.<br />
The below-the-knee incremental impedance is 10,000 V/32 A, or a little<br />
more than 300 ohms. The ratio of the two is almost 250:1.<br />
One of the functions of the load-line/source-line representation is to visualize<br />
what happe,ps when one or another parameter varies. If, for instance, the charac-
