4. Set the baud rate
Setting the baud rate of data transmission is equivalent to specifying the clock
frequency.
Press Baud and turn the multi-function knob to select the desired baud rate.
You can also press Baud continuously to switch the current baud rate. You can
select a preset baud rate or select “User” to specify a baud rate.
The preset vaud rates include 2400 bps, 4800 bps, 9600 bps, 19200 bps,
38400 bps, 57600 bps, 115200 bps, 230400 bps, 460800 bps, 921600 bps
and 1 Mbps.
When “User” is selected, you can set the trigger baud rate. Press Setup;
turn the multi-function knob
or the inner knob of the navigation knob to
adjust the baud rate at a relatively smaller step or turn the outer knob of
the navigation knob to adjust the baud rate at a relatively larger step. The
settable range is from 110 bps to 20 Mbps.
Note: The larger the rotation amplitude of the outer knob of the navigation
knob is, the faster the variation of the value will be. When you need to
adjust the baud rate within a relatively larger range, this function can help
you quickly finish the setting.
5. Select the trigger mode
Press Sweep to select “Auto”, “Normal” or “Single” (please refer to “Trigger
Mode”). The corresponding status light of the trigger mode currently selected in
the trigger control area (TRIGGER) at the front panel turns on.
6. Turn the noise rejection on or off
Press Setting to enter the trigger setting submenu. In this submenu, press
Noise Reject to turn the noise rejection on or off (please refer to “Noise
Rejection”).
