GW Instek GOC-6200 Data Sheet

200MHz CURSOR READOUT ANALOG OSCILLOSCOPE

The GOS-6200 is a 200MHz two-channel, dual-trace, portable oscilloscope designed for general purpose use. A microprocessor-based operating system controls most of the functions of the instrument, including cursor readout and convenient digitized panel settings. On-screen alphanumeric readout and cursor functions are provided for voltage, time, frequency and phase measurement to extraordinary operational convenience. It also has the function of TV Line select for trigger settings for NTSC, PAL and SECAM. Auto-measurements include frequency, period, pulse width and duty cycle with auto-setting function. Ten different user defined instrument settings can be saved and recalled without restriction.

OSCILLOSCOPES

The vertical deflection system has two input channels, each with 11 different basic deflection factors from 2mV to 5V per division. The horizontal deflection system provides single, dual or delayed sweeps from 20ns to 0.5s per division (delayed sweep, 50ms to 20ns per division). The trigger system provides

stable triggering over the full bandwidth of the vertical deflection.
