8. To set bandwidth limit
When high frequency components of a waveform are not important to
its analysis, the bandwidth limit control can be used to reject
frequencies above 20 MHz .
Taking the Channel 1 for example, the operation steps are shown as
below:
1. Press the CH1 button to show channel menu.
2. Select BandWidth in the bottom menu.
3. Select Full in the right menu. The high frequency of the signal will
be allowed to pass.
4. Select 20M in the right menu. The bandwidth is limited to 20MHz.
The frequencies above 20MHz will be rejected.
Use Mathematical Manipulation Function
The Mathematical Manipulation function is used to show the results of
the addition, multiplication, division and subtraction operations between
two channels, or the FFT operation for a channel. Press the Math button to
display the menu on the bottom.
