Congratulations on your purchase of the Elenco® Model XK-700 Digital / Analog Trainer. This trainer is designed to simplify designing of digital and analog circuits. It contains most of the necessary test equipment needed to build and test these circuits.Your XK-700 has four basic trainers in a single package. They are, 5 independent power supplies, an analog trainer, a digital and a bredblock assembly trainer. We shall proceed in describing each trainer in the following sections.Includes(TL-8) Precision screwdriver kit(ET-10) IC pullerCalculator(ST-75) 11 pc. driver set(ST-1) Diagonal cutters(ST-2) Long nose pliers(SP-4) Desoldering pump(LP-560) Logic probe(ST-30) Deluxe wire stripper(SE-1) Solder ease kit(LF-99) Lead-free solder(SW-3) Solder wick(SR-2B) Deluxe soldering iron(ST-20) Safety goggles(SL-5) Deluxe soldering stationFeaturesPower Supply Model XK-700 has five built-in power supplies which will satisfy most design needs. This includes two variable power supplies giving up to +20 volts and -20 volts at .5 amp. Below 15V the current available is over 1 amp. Three fixed power supplies give you +12VDC, -12VDC or +5VDC at 1 amp each. These fixed voltages are the most commonly used voltages for design work. All supplies are regulated to within 150mV. This means that you can increase the current draw from no load to .5 amp and the voltage will change less than 150 millivolts. All supplies are also short circuit protected by using integrated circuit regulator devices.Analog Trainer Section Function Generator The analog trainer contain a complete function generator capable of producing sine, square and triangle waveform. The frequency of this generator is continuously variable from one hertz to over 100,000 hertz in five steps. A fine tuning control makes selection of any frequency easy. The output voltage amplitude is variable between 0 to 15Vpp. The output impedance is approximately 330 ohms.Digital Trainer Section The digital trainer has the necessary functions to do your digital designs. They consist of a clock generator, two no bounce logic switches, 8 LED indicator lamps and 8 data switches. These functions will make it easy to do your digital experiments.
