To Specify Channel Coupling; To Specify Bandwidth Limit - Teledyne T3DSO2000 Series User Manual

To Specify Channel Coupling

Set the coupling mode to filter out undesired signals. For this example, we will assume 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 into the T3DSO2000 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 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 into the T3DSO2000 channel.
� When the bandwidth limit is set to 20MHz, the high frequency components that
exceed 20 MHz are attenuated.
Press the CH1 button the front panel; then press the BW Limit softkey to select Full or
20MHz. 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.
