21. Plug-in Element 4410-3 Calibration
a. Performance Check
(1) Connect equipment as shown in figure 2 above.
(2) Insert plug-in element into TI and rotate until the arrow points in the direction
of the 50 Ω termination.
(3) Set TI range switch to 1 and allow equipment to warm-up for 5 minutes.
(5) Adjust signal generator and RF power amplifier amplitude controls for a TI
indication of 100 W. RF power meter will indicate within limits in table 16.
(6) Repeat technique of steps (4) and (5) above for remaining settings listed in
Table 16. 4410-3 Element Accuracy.
