 LM1600 Series Functional Signal Generator has the function of digital frequency calculation、counter and voltage display. Each port has protection function， efficiently prevent the damage by output short circuit and out circuit current devise. And all that improves the instrument’s liability. Our instrument is fit for teach， electronic experiment， science and research，post，electronic instrument measurement and so on.

The oscilloscope is a dual – channel oscilloscope maximum Sensitivity 5mV/DIV.and maximum sweep time 5nsec/DIV. The oscilloscope employs a 6 - inch rectangular type cathode - ray tube with internal graticule. The instrument features a P – P AUTO trigger and an ALT TRIG. The P-P AUTO trigger level function sets a variable trigger level range according to the trigger signal amplitude to facilitate signal synchronization .
