USB Controlled Attenuator

  GDSA series is single channel USB Controlled Attenuator which support wide frequency range from 9KHz to 6GHz.  It has broad attenuation range from 0 to 95.25dB with 0.25dB step. The attenuator is powered and controlled by USB interface, thus  the external power supply is not necessary. 

  The software package includes a shared library, application programming interface, and control panel software with GUI. The control panel software is designed and developed for ease of use and control of multiple attenuators at once. API supports Python and provides full control over devices with various functions so that programming can be done with a few lines of code.
