General Gain Setup
The General Gain Setup window provides for an up or down adjustment of the gain levels for various parameters included on
the window. The IP-223 is based largely on software controlled resistors with a resolution of 1.5dB per step.
Example: If it is determined the output level for a transmission line is 3.0dB too high, an entry of -3.0dB should be
entered in the corresponding Transmit Gain field for the line.
NAVIGATION: Clicking General Gain Setup displays the General Gain Setup window, shown in Figure 92.
