5.5 BW Limit
This oscilloscope supports the bandwidth limit function. Setting the bandwidth limit
can reduce the noises in the displayed waveforms. For example, the signal under test
is a pulse with high frequency oscillation.
• When the bandwidth limit is disabled, the high frequency components of the
signal under test can pass the channel.
• When the you enable the bandwidth limit, the high frequency components
found in the signal under test that are greater than the limit are attenuated.
Click or tap the channel status label at the bottom of the screen. Then the
Vertical
system menu is displayed. Click or tap the drop-down button of BW Limit to select
the specified bandwidth. When the bandwidth limit is enabled, the specified
bandwidth limit value will be displayed in the channel status label at the bottom of
the screen, as shown in the figure below.
The supported bandwidth limits include 250 MHz and 20 MHz.
• When the vertical scale is greater than 500 μV, the bandwidth limit is disabled.
• When 200 μV/div < vertical scale ≤ 500 μV, the 250 MHz bandwidth limit is
enabled automatically and bandwidth limit cannot be disabled.
• When the vertical scale is equal to 200 μV, the 20MHz bandwidth limit is enabled
automatically and bandwidth limit cannot be disabled.
5.6 Input Impedance
To reduce the circuit load between the oscilloscope and the circuit under test, this
oscilloscope provides two input impedance modes: 1 MΩ (default) and 50 Ω. In the
Vertical system menu, click or tap to select "1 MΩ" or "50Ω" under Impedance.
• 1 MΩ: The input impedance of the oscilloscope is very high, and the current
flowed from the circuit under test can be ignored.
• 50 Ω: makes the oscilloscope match with the device whose input impedance is
50 Ω.
After modifying the input impedance value, the circuit diagram in the Vertical system
menu will also be changed, as shown in the figure below.
