[0016] Such as figure 1 As shown, the on-off target and target signal conditioning and verification device of the present invention includes a CPLD verification control unit 1 and a signal conditioning unit 2;
[0017] The CPLD verification control unit 1 is used to use CPLD to generate 32 groups of single pulse signals to verify the accuracy of the system time interval measurement. The single pulse signals are two channels per group, and the time interval between signals for sure;
[0018] The signal conditioning unit 2 is used to adjust the external input pulse signal and the output signal of the CPLD by setting the threshold level of the comparator to eliminate the influence of noise in the circuit and avoid false triggering;
[0019] The output terminal of the CPLD check control unit 1 is connected to the input terminal of the signal conditioning unit 2.
[0020] Still as figure 1 As shown, the CPLD verification control unit 1 includes a CPLD programmable logic device module 11, a...
