•
When the bandwidth limit is turned off, the high frequency components of the
signal under test can pass the channel.
•
When the bandwidth limit is turned on, the high frequency components found in
the signal under test that are greater than the limit are attenuated. HDO1000
series oscilloscope supports 20 MHz bandwidth limit.
Click or tap the channel status label at the bottom of the screen. Then the Vertical
menu is displayed. Click or tap the BW Limit drop-down button to select the
specified bandwidth. When the bandwidth limit is enabled, the character "Bw" will be
displayed in the channel status label at the bottom of the screen, as shown in the
figure below.
TIP
Bandwidth limit can not only reduce the noise, but also can attenuate or eliminate the high
frequency components of the signal.

To Specify Input Impedance
This series oscilloscope provides 1 MΩ input impendance mode. In this mode, the
input impedance of the oscilloscope is very high, and the current flowed from the
circuit under test can be ignored.

To Invert a Waveform
Click or tap the channel status label at the bottom of the screen, and then the
Vertical menu is displayed. Then click or tap the Invert on/off switch to enable or
disable the waveform invert function.
When "ON" is selected, the channel label is as shown in the figure below.
