Harmonics
1. Use the Selective Level Meter to measure
values of the 2nd, 3rd, and 5th harmonics at
the set frequency.
2. Push the “HL” test button on the Keying
module; observe fundamental and harmonic
levels across the load to be:
Fundamental: +40 dBm (22.4 Vrms) ±0.2
dBm
Harmonics: Less than -15 dBm (55 dB
below fundamental level)
