WFG Board
Guardian baseboard with Red Pitaya waveform generator

Wave types: Sine, triangle and square
Amplitude: ± 10 V
DC offset: ± 10 V
Frequency range: 0.1 Hz to 10 MHz
Signal switchable to SMB female connector or analogue bus

Description

The Red Pitaya module, that was developed by STEM-Lab (redpitaya.com), has been integrated into our Guardian test system with a baseboard. The baseboard controller firmware communicates with the WinGuard software and the module via two UART interfaces. The baseboard amplifies the signal of the module by a factor of 10 to ± 10 V and switches the output for each relay via the SMB female connector either to the power connector or the 3 + 4 analogue bus of the Guardian system. This allows the signal to connect to the desired test points via the relay matrix of the test device.

Applications

Testing audio components
Clock generator
Control of components with PWM inputs
Sine wave signals for LCR measurements
DC voltage transmitter
