Modulation Waveform
In this clause, the RF output waveform is described when the
Modulation field is set to
Off, AM Modulation 1 or AM Modulation
2.
When the Modulation is set to Off
The Tester outputs continuous wave (CW). The output
frequency is set in the RFCH field. The output level is set in the
Amplitude field. The output signal is shown in Figure 5-61.
When the Modulation is set to AM Modulation 1
The Tester outputs amplitude modulation wave. The carrier
frequency is set in the RFCH field. The carrier level is set in the
Amplitude field. The carrier is modulated by 20 kHz sine wave.
The modulation degree is 56%. The output signal is shown in
Figure 5-62.
