Setting Up Channels
Each channel has its own separate Menu. The items are set up
separately according to each channel.
1. Setup Channel Coupling
Take CH1 for example; the tested signal is a sine wave signal
with DC deflection:
• Press“CH1”→“Coupling”→“AC”, Set to AC couple mode.
This will block the DC component of the input signal.
• Press“CH1”→“Coupling”→“DC”, Set to DC couple mode.
Both DC and AC components of the input signal will be
captured.
• Press“CH1”→“Coupling”→“GND”, Set to GROUND mode.
This disconnects the input signal.

2. Bandwidth Limiting
Take CH1 for example:
• Press “CH1”→“BW Limit”→ “On”, and bandwidth will be
limited to 20 MHz.
• Press“CH1”→“BW Limit”→ “Off”, and bandwidth limit
will be disabled.
