A remote real-time system, which can generate multi-channel calibration signals and trigger signals, is designed to check the state of data acquisition devices in the strong radiation environment. Monostable circuit is adopted in order to avoid that the command is executed for many times because of the switch bounce. Based on principle of directly modulated semiconductor laser, indirectly coupled mode is used to isolate the command pulse from the DC bias of the laser. Using digitally programmable delay generator AD9501, the delay time accuracy between the calibration signal and the trigger signal is up to 1ns, the time jitter is no more than 1ns.The operational amplifier with the high driving capability meets the needs of the multi-channel output and ensures the identity of multi-channel signals. The system can simultaneously check and calibrate multiple data acquisition devices.
