UserScope Firmware

Firmware developed by Hongyi Wu(wuhongyi@qq.com/wuhongyi@pku.edu.cn). This firmware focuses on recording ultra-long waveforms.

Currently supports firmware customization for models 2740/2745/2730/2751. Teachers with special firmware requirements are welcome to contact us.

Basic Parameter Configuration

Input Signal

Parameter: ChEnable

Independently sets whether each channel is enabled for use. If a channel is not enabled, it does not provide any data, and its self-triggering is also disabled.

Parameter: DCOffset

When the input signal is of positive polarity, DCOffset 0% corresponds to channel address 0; when the input signal is of negative polarity, DCOffset 100% corresponds to channel address 0.

UserScope

Parameter: Polarity

Set to 1 when the input signal is of positive polarity, and to 0 when it is of negative polarity.

Parameter: FL

Parameter for XIA fast filter (fast trapezoidal filter parameter).

The unit for FL is 8 ns. Configurable range is 1-127.

Parameter: FL+FG

Fast trapezoidal filter parameter.

The unit for FL+FG is 8 ns. This parameter must be greater than or equal to FL. Configurable range is 1-127.

Parameter: Threshold

Trigger threshold for the fast trapezoidal filter.
