Instek GDS-1102A-U
100 MHz Digital Storage Oscilloscope

Coupled with the high resolution 5.7” color TFT display, with user-friendly interface USB device and host port make the GDS-1000A series feature-rich.

ABOUT MemoryPrime TECHNOLOGY

What is the single feature lacking from most digital storage oscilloscopes? Adequate memory depth. Is the memory depth of your DSO large enough?

With 2M points of memory, the GDS1102A-U has the capability to acquire far more waveform data compared to other DSOs in the same performance range.

The 1GSa/s sampling rate and 2M point memory play an extremely powerful role for single-shot waveform capture. Properly set the trigger conditions to baby-sit the expected waveform. When the single-shot waveform is triggered and captured, you are able to check and see the single-shot event without losing any detailed information. A DSO, with high sampling rate but short memory, can't do the job of single-shot waveform capture as well as the GDS1102A-U.

Ease of Use

Full-featured acquisition mode and 27 auto measurement functions help users to measure the parameters of captured waveforms accurately. The advanced Auto-Set function enables GDS-1000A-U Series to catch waveform automatically and display waveform quickly. With Arithmetic functions, +, -, x, FFT, FFTrms and Zoom FFT. GDS1102AU Series keep users aware of the measurement results by updating values immediately. Without almost extra calculation, GDS-1102A-U can provide sufficient information of testing.

Observation-Delay ON/OFF

For the convenience of waveform observation and analysis, the GDS1102AU includes Delay On/Off functions usually available only in the higher end products. With Delay On, a signal can be observed from an offset of the trigger point. This feature allows the horizontal scale and the waveform scale to be expanded and centered on the delay point rather than the trigger point, allowing a signal to be observed in detail where needed.

Observation-Expand by Ground/Center

In a DSO, "AC Coupling" is normally used to isolate the AC components of a signal by blocking the DC components. This is useful to see a signal with a small AC component that is offset with a large DC voltage. With AC coupling to block the DC voltage, small AC waveforms can be observed from the center of the screen for measurement or examination. However, capacitive loading under AC coupling mode may cause waveform distortion as low frequency components become degraded, an effect that needs to be avoided in frequency critical applications. The Expand by Ground and Center functions are convenient tools to expand a waveform vertically. With this feature, the vertical scale of a waveform can be expanded either from the ground reference or from the center of the screen without causing capacitive loading.

FFT / FFTrms and Zoom FFT Measurement

The FFT math function on a digital storage oscilloscope is often used to observe the fundamental and harmonic components of a signal. Typically the traditional unit of the FFT is a decibel (dB). However in the use of dB, it is difficult to identify the fundamental frequency of a signal from a noisy spectrum sometimes. With the FFTrms function, the GDS-1000A-U series can clearly display the fundamental frequency of an acquired waveform. With the FFTrms function, the GDS-1000-A-U series can clearly display the fundamental frequency of an acquired waveform. Zoom FFT provides users with observation flexibility that they can move FFT waveform horizontally and zoom it up to 20X to investigate details of FFT signal.

PC Remote Control Software

Using a USB port coupled with FreeWave remote monitoring software is the easiest and most convenient way to capture data from the GDS1102A-U. With FreeWave, a screenshot can be saved as an image file (.bmp/.jpg), waveform data(.csv) can be logged, and movie files(.wmv) can be recorded in real-time. Not only can FreeWave monitor and record waveforms over a long period of time, but previously recorded waveforms can also be observed. Instrument settings can even be configured without the need to learn incomprehensible command line syntax. With the simple user interface and robust features, FreeWave allows you to get the most out of the GDS1102A-U with little effort.

USB Host & Data Logger

USB host function enable user to store waveform setting ,data or image on USB flash disk. Furthermore, the data logger can continue monitoring input signals and storing their waveform data in USB flash disk when trigger conditions are met, saving users' effort to tracking signals manually and allowing them to analyze and observe waveform data afterwards.

Go/NoGo Function

Go/NoGo testing function check whether the incoming signal violates the user-defined template. Users can easily define this template by setting the tolerance ratio to determine violation conditions. Go/NoGo testing can either keep counting violation number or stop testing when violation conditions are met.
