This all-in-one-instrument is a unique, hand held re-chargeable battery operated Instrument is a combination of 5MHz Single Channel Oscilloscope with 3-3/4 Digits Digital Multimeter with RS-232 Interface cable, 5MHz Function Generator, 1.3GHz Frequency counter and Single Channel Logic Analyzer for TTL, 3V CMOS and 5V CMOS.

It has a large LCD 160 x 160-pixel High Density Graphical display. In the Oscilloscope Mode it displays waveform up to 5 MHz frequencies and has a sampling range of 25 MSPS and the rising time is less than 15ns. It has an input protection up to 600V pp max. The vertical sensitivity can be adjusted from 10mV / Div to 200V/ Div and the horizontal sweep can be adjusted from 125ns - 2 s/div. It has both auto and normal triggering. The cusrsor measurement of DV, DT and 1/DT. It can store up to 15 waveforms that can be recalled later.

In the Digital Multimeter model it works as a 3-3/4 Digits 4000 Counts Multimeter and can be used to measure AC Voltage, DC Voltage, AC Current, DC Current, Resistance, Frequency, Capacitance, audible continuity testing and dBm. In the frequency counter mode it measures up to 1.3 GHz with 8 digits display and time period measurements from 5 Hz to 100 MHz. In the function generator mode it gives an output in triangular, sine and square waves of frequency varying from 2 Hz to 5Mhz and with the amplitude varying from 2V to 10V p-p. The duty cycle is adjustable and it also provides a simultaneous display of frequency, duty cycle and amplitude.

In the logic analyzer mode it can be used for TTL, 3V CMOS and 5V CMOS circuits. It comes complete with RS-232 Interface cable and software, battery charger adaptor, oscilloscope probe, test leads, operator's manual and holster. It can also be connected directly to a EPSON Thermal printer.
