The nominal outputs for the 3 µW, 30 µW, 300 µW, 3 mW, 10 mW,
30 mW and, 100 mW settings are 3.16 µW, 31.6 µW, 316 µW,
3.156 mW, 10.03 mW, 31.78 mW, and 101.3 mW respectively.
It is not necessary to check instrument accuracy in dBm. The
power meter uses the same internal circuitry to measure power
and mathematically converts watts to dBm.
