Harp Multi PWM Generator

This board provides 4 independent PWM outputs that can be triggered by four different input triggers or all at the same time. Also four output synchronization signals are available. The PWM signal generation is configured in software.

Key Features

• PWM output generation
• Configurable frequency and duty cycle
• Frequency up to 32 KHz
• Enabling mechanisms by software or hardware to prevent erroneous triggers
• Start and stop triggers (also by software)
• Infinite or configured number of pulses
• Complete trigger mechanisms

Connectivity

• 1x clock sync input (CLKIN) [stereo jack]
• 1x USB (for computer) [USB type B]
• 1x 12V supply [barrel connector jack]
• 5x Digital input triggers: CH0 to CH3, ALL [BNC]
• 4x Digital output PWM signals: CH0 to CH3 [BNC]
• 5x Digital output sync signals: CH0 to CH3, ALL [BNC]

Interface

The interface with the Harp board can be done through Bonsai or a dedicated GUI (Graphical User Interface).

In order to use this GUI, there are some software that needs to be installed:

1 - Install the drivers.

2 - Install the runtime.

3 - Reboot the computer.

4 - Install the GUI.
