1 Harmonic filter can be removed as an option. Add 0.25 dB to amplifier output for units
ordered without harmonic filter. Output VSWR without harmonic filter is 1.25:1 max.
2 Prime power AC line unbalance not to exceed 3%. Excess imbalance may cause an
increase in residual RF noise (AM, FM and PM). Phase noise increase is typically 2.5 dB /
% imbalance.
3 AC current harmonic content: less than 20%, primarily fifth and seventh harmonics.
Harmonics must be considered when choosing UPS sources.
4 Lower power consumption can be achieved if power saver (included as standard)
is employed when operating below rated output power.
