Abstract :
The evolved 100 kHz PWM-CTA extends the technology of the previous generation (50 kHz PWM-CTA) by doubling the sample frequency to 100 kHz, thereby improving the pulse width time resolution by a factor of 2:1. Substantial design changes serve to reduce the noise level in comparison with the previous generation 50 kHz PWM-CTA. An enhanced computer-based user interface has been implemented to simplify system operation.
