Channel Coupling
The undesired signals can be filtered out by setting the coupling mode. For example,
the signal under test is a square waveform with DC offset.
When the coupling mode is "DC": the DC and AC components of the signal under
⚫
test can both pass the channel.
When the coupling mode is "AC": the DC components of the signal under test
⚫
are blocked.
When the coupling mode is "GND", the DC and AC components of the signal
⚫
under test are both blocked.
Press 1 to open the setting menu of CH1. Then, press Coupling continuously or
rotate the multifunction knob
is DC). The current coupling mode is displayed in the channel status label at the
bottom of the screen, as shown in the figure below. You can also enable the touch
screen, and then touch the CH1 setting menu to select the desired coupling mode.
Bandwidth Limit
MSO5000 series 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 you enable the bandwidth limit and limit it to 20 MHz, 100 MHz, or 200
⚫
MHz, the high frequency components found in the signal under test that are
greater than 20 MHz, 100 MHz, or 200 MHz are attenuated.
Press 1 to open the setting menu of CH1.Then, press BW Limit continuously or
rotate the multifunction knob
the knob to select it. By default, it is OFF. When the bandwidth limit is enabled, the
character "B" will be displayed in the channel status label at the bottom of the screen,
