The principle of operation of the device

The synchrobox is assembled on the basis of a microcontroller. The reference frequency source is a quartz oscillator, which ensures the accuracy of maintaining a frequency of 100 ppm.

The architecture of the system allows you to set the timing pulse delays in the range from 0 to 4 seconds, with a discreteness of 1 ms. The pulse duration can be in the range of 4 – 4000 ms, with a discreteness of 4 ms. The polarity of the pulse can be forward and reverse. It is set individually for each channel.There are 2 groups of channels A B and C D in the block.A repeatability period is set for the group of channels A and B. The delay is set for the 2nd group of channels, relative to the first one. Up to 3 pulses of channels C D can be implemented within the period of repetition of the signal on channels A to B.The accuracy of the coincidence of the leading edges of the pulses is < 1 microsecond.

The output is a TTL signal with a range of 0 – 5 V. The load capacity is at least 20 mA, short circuit protection is present. The current sources at all outputs are independent and have optical isolation.
