The GW Instek GDS-1202B is a 200 MHz 2 channel digital oscilloscope that offer users a more affordable and excellent basic DSO Oscilloscope. The full functionalities within this simple-in-look oscilloscope, including parameter measurement, cursor indication, digital voltage meter, and data logging, surpasses the same category 1000 series oscilloscopes in the market. GW Instek provides a very thoughtful design ─the zero key function, which allows engineers to work more effectively. The GDS-1202B oscilloscope also provides OpenWave connection software, which allows users to conduct waveform observation and data storage controlled by remote PC.
