8. IF output signals
This section shows a typical signal at output from DF990 when pointed to the wall at certain distance.
This section means to serve as a guide.
Tuning Voltage Frequency: 10 KHz
Tuning Voltage Range; 1-6V
Sweeping Type; Triangle Function.
Figure 8 shows the signal at IF output when there is no target in the detection range of sensor.
Channel 2 (the blue line) indicates tuning voltage while Channel 1 (the yellow line) is the signal from Q
channel.
Figure 8: IF Output Signal and Input Tuning Voltage with no targets detected.
Figure 9 shows the signal at IF output when there is target in the detection range of sensor.
Channel 2 (the blue line) indicates tuning voltage while Channel 1 (the yellow line) shows the signal of
Q channel.
