(4) Select 20M in the right menu. The bandwidth is limited to 20 MHz. The frequencies
above 20MHz will be rejected.
6. To set the input impedance (only for certain models)
To reduce the circuit load caused by the interaction of the oscilloscope and the circuit to
be tested, you can set the input impedance.
Taking the Channel 1 for example, the operation steps are shown as below:
(1) Push the CH1 button to show CH1 SETUP menu.
(2) Select Input IMP in the bottom menu, push to select 1MΩ or 50Ω.
1MΩ: The input impedance of the oscilloscope is rather high and the current flowing
into the oscilloscope from the circuit under test can be ignored.
50Ω: Match the oscilloscope with a device with 50 Ω output impedance. The max
input voltage cannot exceed 5 Vrms.
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, the FFT
operation for a channel, advanced math feature including Intg, Diff, Sqrt, user defined
function, and digital filter. Press the Math button to display the menu on the bottom.
