To Specify Channel Coupling
Set the coupling mode to filter out the undesired signals. For example, the signal under
test is a square waveform with DC offset.
 When the coupling mode set to DC: the DC and AC components of the signal under
test can both pass the channel.
 When the coupling mode set to AC: the DC components of the signal under test are
blocked.
 When the coupling mode set to GND: the DC and AC components of the signal under
test are both blocked.
Press the CH1 button on the front panel; then press the Coupling softkey and turn the
Universal Knob to select the desired coupling mode. The default setup is DC.
The current coupling mode is displayed in the channel label at the right side of the screen.
You can also press the Coupling softkey continuously to switch the coupling mode.
To Specify Bandwidth Limit
Set the bandwidth limit to reduce display noise. For example, the signal under test is a
pulse with high frequency oscillation.
 When the bandwidth limit set to Full, the high frequency components of the signal
under test can pass the channel.
 When the bandwidth limit set to 20M, the high frequency components that exceed 20
MHz are attenuated.
Press the CH1 button on the front panel; then press the BW Limit softkey to select Full or
20M. The default setup is Full. When bandwidth limit is enabled, the character B will be
displayed in the channel label at the right side of the screen.
At 2 mV/div volt scale, the BW Limit is set to 20M automatically, and cannot be turned off.
