GW-DS Oscilloscope 100MHz 2-CH 2GSa/s (RTS) / 100GSa/s (ETS)

Product Overview

Digital Storage Oscilloscope: The GDS-2102A from GW-INSTEK is a 2-channel oscilloscope with 100 MHz bandwidth. The unit captures and displays electrical signals in real-time, offering both real-time and equivalent-time sampling for detailed measurement of time-domain signals.

Function and Application

The GDS-2102A is used for acquiring, displaying, and analyzing time-varying electrical signals on two analog channels. The instrument provides:

• Real-time sampling of up to 2 GSa/s in single-channel operation and 1 GSa/s with two channels.
• Equivalent-time sampling (ET) up to 100 GSa/s for higher time resolution of repetitive signals.
• Segmented memory and search function for handling longer recordings and quickly locating relevant waveforms (specified in the manufacturer's documentation).

The description and specifications in the manufacturer's material indicate how the GDS-2102A handles both acquisition and analysis (e.g., FFT, measurement functions, and cursors). The instrument's vertical sensitivity and time base allow for adaptation to various signal levels and speeds within the specified limits.
