Digital electric circuit learning machine provide various signal source, front side print character wiring, reverse side install the component, all the signal source frequency meter are constituted by CPLD chip and double-side board, all the component adapt high quality product, improve the whole machine quality. Because the component are installed on the reserve side, so it can reduce and avoid the possibility of man-made damage.

Product characteristic: easy to operation, durable, experiment project flexible, it easy to carry out various the digital simulation experiment.

System content:

Power supply: AC input: 220V±10% , 50HZ

DC output: ±12V/200mA, 5V/2A

Manual mono pulse electric circuit two group: it can output the positive and negative pulsed in the meantime, pulse amplitudes is TTL electrical level.

Fixed frequency impulse source: 1HZ,1KHZ,10KHZ,100KHZ,1MHZ

Six- bit high accuracy digital frequency meter, measuring range: 0-9.9999MHZ error<1HZ ( design by CPLD chip )

Continuous pulses one group: output is TTL electrical level.

The output and display of logic level.

Nixie tube display

Four-bit BCD code decode display electric circuit constituted by LED nixie tube.  

One-bit eight segment nixie tube, pin totally lead out, it used for nixie tube experiment.

Eight- bit independent logic level switch: it can output "0","1" electrical level ( it is positive logic.

The logic electrical level constituted by eight- bit red LED and drive electric circuit.
