NOTE
In higher TI ranges it may be necessary to increase RF
amplifier gain above 50%.
and output to -45 dBm. Slowly increase signal generator output and, if necessary, power
amplifier gain for RF power meter indication listed in table 15 corresponding to 1 W range.
If TI does not indicate within limits specified in table 14, perform b below.
(12) Repeat technique of (11) above for remaining TI ranges and source outputs listed
Table 15. Power Meter Accuracy (1 W 200 W).
