The GOS-6000 Series Analog Oscilloscopes provides a remarkable combination of high performance and compact design in bandwidth ranging between 30 and 50 MHz. Coupled with various trigger functions, waveforms can be acquired and observed in diverse application fields. Signals can be magnified by a ratio of x5, x10 and x20 in the use of the ALT MAG function. Together with the Cursor Readout and Frequency Counter functions (GOS-6051/6031), the GOS-6000 Series offers tremendous value for your investment in testing and analysis.
