GW Instek (www.gwinstek.com) has introduced a four channel oscilloscope that offers a spilt screen feature to meet the demands of multi-window and multi-signal tests in research and manufacturing fields. With a record length of 25 k points, the GDS-3354 delivers a real-time sampling rate of five GSa/s and an equivalent time sampling rate of up to 100 GSa/s.

This 350 MHz oscilloscope also offers a rise time of 1ns and a vertical resolution of eight bits.

Its unique split screen feature enables each input channel to be independently operated with respective waveform display and setting. The vertical sensitivity, trigger selections and time base can be separately performed by each channel, while the waveform of every input signal can be displayed on the screen’s individual part. The almost four-DSO-in one feature is useful for applications that have to simultaneously view the details of multiple waveforms with varying characteristics. This eight-inch high resolution 800×600 LCD display offers a pleasant viewing environment to observe the details of complex signals.

Aside from edge trigger, the oscilloscope’s advanced trigger functions also include Pulse Width, Video, Rise Time and Fall Time, Delay by Time, Alternate, Delay by Event, Runt and Hold-off. Its VPO signal processing and display, high sampling rate and flexible trigger function all contribute to make the GDS-3354 a potent tool for waveform capture as well as display of different kinds of signals.

The oscilloscope’s Auto Range function automatically adjusts the vertical scale and/or the time base of the displayed waveform when the amplitude and/or frequency of the input signal change.

Meanwhile, the Zoom function of the oscilloscope offers dual display mode to simultaneously show the main waveform as well as the magnified portion of the zoomed-in waveform.
