GENERAL NOTES:
1. Vis is the input voltage at nY or nZ terminal, whichever is assigned as an input.
2. VOS is the output voltage at nY or nZ terminal, whichever is assigned as an output.
NOTES:
1. Adjust input voltage Vis is 0 dBm level (0 dBm = 1 mW into 600 W).
2. Adjust input voltage Vis is 0 dBm level at VOS for 1 MHz (0 dBm = 1 mW into 50 W).
