Data processor and data processing method for wavemeter

摘要

The CPU outputs to the delay circuit 22 delay time setting signals for setting the delay time, based on input delay time data input from an external input device. The delay circuit 22 re-sets the delay time via new delay setting signals input from the CPU 24 and delays the trigger signals input from the trigger circuit 21 based on the specified delay time and outputs the resulting signals to the clock generator 23. The clock generator 23 outputs new sample start signals to the A/D sampler 3 at the input timing of the delayed trigger signals input from the delay circuit 22, thus changing the sampling start timing of interference signals in the A/D sampler.
