GW Instek GDS 320 handheld Oscilloscope
The GW Instek GDS 320 is a portable digital oscilloscope featuring a 3.5-inch TFT LCD display with 320x240 resolution, designed for field service technicians and electronics engineers who require real-time waveform analysis without being tethered to a lab bench. This handheld instrument delivers 200 MHz bandwidth with dual channels, capable of capturing signal frequencies up to 1 GHz using advanced digital sampling technology, making it ideal for troubleshooting power supplies, signal integrity testing, and embedded system debugging. The GDS 320 solves the critical problem of rapid field diagnostics by combining portability with professional-grade measurement accuracy, eliminating the need for expensive benchtop oscilloscopes in field service operations.
Product Overview
The GW Instek GDS 320 operates on the principle of real-time digital sampling, capturing analog signals and converting them to digital format for display and analysis on its compact LCD screen. The oscilloscope features a dual-channel architecture with independent vertical controls, allowing simultaneous measurement of two different signals with vertical resolution of 8 bits per sample. Its 200 MHz analog bandwidth ensures accurate reproduction of signal characteristics up to the Nyquist frequency, while the maximum real-time sampling rate of 1 GSa/s enables precise capture of fast transient events and high-frequency components. The instrument incorporates advanced triggering modes including edge, pulse width, and video triggering, essential for isolating specific signal anomalies in complex waveforms.
What distinguishes the GDS 320 in the handheld oscilloscope category is its combination of measurement depth and portability. The device includes 2 kS of waveform memory per channel, sufficient for capturing multiple cycles of low-frequency signals while maintaining adequate time resolution. The built-in function generator capability with sine, square, and triangle waveforms makes it invaluable for circuit stimulation and response testing. The rugged construction with integrated handle and protective casing ensures reliability in harsh field environments, while the lithium-ion battery provides up to 4 hours of continuous operation, eliminating dependency on AC mains during on-site troubleshooting.

How to Use
Begin by powering on the GDS 320 and allowing the display to initialize. Connect your signal source to either Channel 1 or Channel 2 using the supplied BNC probe cable, ensuring proper grounding by connecting the probe ground clip to a reference point on your circuit. Set the vertical scale (volts per division) using the rotary control to position the signal within the display window, typically starting at 1V/div for unknown signal amplitudes. Adjust the timebase control to display 2-3 complete signal cycles on screen, allowing visual assessment of waveform shape and frequency content.
Activate the appropriate trigger mode by pressing the trigger menu button and selecting edge trigger for standard applications. Set the trigger level to the midpoint of your signal amplitude to ensure stable waveform capture. For precise frequency measurement, utilize the cursor measurement tools to mark peak-to-peak voltage and period, with the oscilloscope automatically calculating frequency and RMS values. When capturing transient events, enable single-shot mode to freeze a single waveform occurrence, then use the pause function to examine details before resuming continuous acquisition. For extended field diagnostics, enable the battery power indicator and plan your measurements within the 4-hour operational window, utilizing the waveform storage feature to archive critical measurements for documentation.
Frequently Asked Questions
What is the maximum voltage range that can be safely measured with the GDS 320?
The GDS 320 can measure signals within the range of 0 to 400V peak when using the standard 10:1 attenuation probe supplied with the instrument. The vertical sensitivity ranges from 10 mV/div to 10 V/div, allowing measurement of both low-level analog signals and higher voltage digital logic levels. For measurements exceeding 400V, external high-voltage probes rated for your specific voltage range must be used, with appropriate attenuation factors entered into the oscilloscope settings.
Can the GDS 320 measure AC and DC components simultaneously?
Yes, the GDS 320 features independent AC and DC coupling options for each channel, selectable via the channel menu. DC coupling displays the complete signal including any DC offset, essential for measuring power supply ripple and bias voltages. AC coupling removes DC components and amplifies small AC signals superimposed on larger DC levels, useful for analyzing audio signals and modulation components. The oscilloscope also provides automatic DC offset measurement and display, allowing you to quantify the DC bias present in your signal.
How does the 2 kS memory depth affect waveform capture capability?
The 2 kS (2000 samples) memory per channel determines the maximum time window that can be captured at full sampling rate. At the fastest timebase setting of 5 ns/div, the entire 10-division display represents 50 nanoseconds, consuming approximately 50 samples. At slower timebases, the memory allows capture of longer duration signals, for example at 100 ms/div, the full 1-second window uses all 2000 samples. For very slow signals requiring extended capture time, you can reduce the sampling rate or use the waveform storage feature to archive multiple acquisitions.
