Input Impedance
This coscilloscope provides two input impedance modes (1 MΩ (default) and 50 Ω) to
reduce the circuit load caused by the interaction of the oscilloscope and the circuit to
be tested.
1 MΩ: the input impedance of the oscilloscope is rather high and the current
1 MΩ: the input impedance of the oscilloscope is rather high and the current
flowing into the oscilloscope from the circuit under test can not be ignored.
50 Ω: match the oscilloscope with a device with 50 Ω output impedance.
Press CH1 Input to set the input impedance of the oscilloscope. When “50 Ω” is
selected, “Ω” is displayed in the channel label at the bottom of the screen.
