Fig.12 Cross-modulation distortion as a function of
output power.
Three-tone test method (vision carrier−8 dB, sound carrier −7 dB, sideband signal −16 dB), zero dB corresponds to peak
sync level (see Fig.11). Intermodulation distortion of input signal ≤−70 dB.
Two-tone test method (vision carrier 0 dB, sound carrier −7 dB), zero dB corresponds to peak sync level.
Cross-modulation distortion (dcm) is the voltage variation (%) of sound carrier when vision carrier is switched from
0dBto−20 dB (see Fig.12).
Ruggedness in class-A operation
The BLV33F is capable of withstanding a full load mismatch corresponding to VSWR = 50 : 1 through all phases up to
30 W (RMS) or 40 W (PEP) under the following conditions: V
R
1. Gain compression point of 1 dB is at typical 85 W (minimum 75 W). Using a 3rd-order amplitude transfer
characteristic, 1 dB compression corresponds with 30 % sync input / 25 % sync output compression in television
service (negative modulation, C.C.I.R. system).
