Parameters 21-23, TX Audio Freq Response Start, Step, and Stop Frequency
Parameters 21-23, TX Audio Freq Response Start, Step, and Stop Frequency
The start frequency test parameter sets the lowest modulation frequency used for
testing the transmitter’s audio frequency response.
The step frequency test parameter sets the step size used to vary the modulation
frequency for testing the transmitter’s audio frequency response.
The stop frequency test parameter sets the highest modulation frequency used for
testing the transmitter’s audio frequency response.
For Example:
If your industry standard determines that the modulation frequency used for
testing the transmitter’s audio frequency response should start at 300 Hz and stop
at 3 kHz in 500 Hz steps, enter:
• 0.3 in the value column for test parameter 20.
• 0.5 in the value column for test parameter 21.
• 3 in the value column for test parameter 22.
The values are entered in kHz.
It’s Used in the Following Tests:
TEST_05. TX Audio Frequency Response
TEST_21. TX Quick Test
