5. Trapezoid Pattern Balanced Modulator More often than not a nonlinear trapezoidal pattern is the result of a mistuned amplifier particularly with the load control being set with insufficient loading To test this simply advance the load control slightly With more loading of the amplifier you will more than likely see the widest side of the trapezoid edges become nice and crisp as seen in Figures 10a and 16 above If the resulting patterns displayed on the oscilloscope station monitor are well formed your unintelligible distortion products will be significantly reduced resulting in a one to one ratio between your audio frequency and radio frequency bandwidth This is a step in the right direction and is more than most hams ever attempt to do in analyzing their on air signal purity 14 15 Application 3 Using Oscilloscope as an Instantaneous Peak Reading Power Meter Select oscilloscope envelope Application 1 or XY Application 2 monitoring mode With a continuous carrier established at the desired power level measured by and existing in line watt meter adjust Vertical CH 2 Y Voltage Gain control so your pattern extends plus minus two divisions vertically See Figure 3 and 10D Now any time your modulated SSB or AM pattern extends to reach the vertical plus minus two divisions mark you will be exactly at the relative power you established with the in line watt meter during the continuous carrier See Fig
