11.5. 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.
12. Implementation of Mathematical Manipulation Function
The
Mathematical Manipulation
function is
used to show the results of the addition, multiplication, division
and subtraction operations between Channel 1 and Channel 2, and the FFT operation of Channel 1 or
Channel 2
.
