Setting of Band 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 MENU button to call out the CH1 SETUP menu.
(2) Press the H4 button and the Limit menu will display.
(3) Press the F1 button to select the Band Limit as full band. The high
frequency of the signal will be allowed to pass.
(4) Press the F2 button to select the Band Limit as 20M.The bandwidth is
limited to 20MHz.The frequencies above 20 MHz will be rejected.
Implementation of Mathematical Manipulation Function
The Mathematical Manipulation function is used to show the results of the
addition,multiplication, division, subtraction operations and the FFT operation
between Channel 1 and Channel 2.
