The instrument consists of sine wave generator filter circuit and meter. Workable 220 V 50 H. The capability of this instrument is to measure distortion in audioable range 20 Hz to 20 KHz Dual Trace Oscilloscope It is a 20 MHz Dual Channel Oscilloscope that s ideal for, professionals as well as students undergoing technical studies. It is a rugged, light weight instrument that features a brijght, sharply defined trace on a 80 by 100 mm cathode ray tube. The internal trigger signal is ac coupled. An external triggering signal or an external Z-axis modulation signal can be applied via a front panel or rear panel connector and the source selector switch. The horizontal system provides calibration sweep speeds from 0.2s to 0.1 Micro S per division. For greater measurement accuracy a x5 magnifier circuit extends the maximum sweep speed to 20 ns per division. Special Features : Synchronisation of the signals from the two channels can be identified by a Red LED, marked as "READY", present on the right hand side top on the front panel.
