3.2.1 Noisy Sine Signal
1.
Signal Explanation
Signal Output Pin:
NOISY_SINE
500 kHz, 1Vpp sine waveform on which a 25MHz, 300mVpp high-frequency noise is
superimposed.
2.
Functions
High-frequency reject, bandwidth limit, FFT
3.
Demonstration and Result
Connect the signal output pin NOISY_SINE and GND to CH1 of the oscilloscope properly using
the probe;
Set the trigger type to “Edge”, the trigger holdoff to “600us”, the sample mode to “Normal” and
the vertical scale to “500 mV”; adjust the vertical position and trigger level to appropriate values
to make the oscilloscope trigger stably. The demonstration result is as shown in the figure
below.
