We are offering analog and digital trainer (adt)
features: high level, high quality digital-analog trainer
combines all essential functions of analog and
digital experiment with removable breadboard,
includes dc power supply,function generator,two pulse switches, 8 ohm 0.25w speaker etc.
Specifications
solder-less,breadboard
interconnected with tie points nickel plated contact, fitted with all dip sizes and all components with lead and solid wire. It can be changed and replaced for different purposes and can be connected with demonstration panel. Therefore, it is very convenient for both teachers and students
dc power supply

amplitude
sine wave output : 0 ~ 6 vpp variable @ 1hz~1mhz in 5 steps
triangle wave output : 0 ~ 6 vpp variable @ 1hz~ 300khz in 5 steps
square wave output : 0 ~ 5 vpp variable @ 1hz~400khz in 5 steps
ttl mode output : 5v@1hz~1mhz in 5 steps
two digits of 7 segment led display
two pulse switch: push buttons to generate inverting and non inverting pulses supportedwithde-bounce elimination
data switches: toggle switches and corresponding output point. When switch is set at“down”position, the output is lolevel, contrarily it is tobe'high' level while setting at“up”position
speaker: 8ohm0.5w to be used for load
the two banana sockets and bnc jacks suitable for the trainer to beconnected with peripherals
red leds separate input terminals. The led will be lighted up wheninput is at“high level”and it will be turned offwhenit is at“noinput”or at “lowlevel”
zif sockets : 40-pin, 28-pin, 20-pin
