4CH & 2CH Selection
|
|
4-channel models have joined the product lineup in addition to the traditional 2-channel models. The vertical scale of each channel carries the full bandwidth of the model at 200MHz, 100MHz or 60MHz. With 4 full bandwidth channels, a larger range of applications are possible. Typical examples of four-channel applications include testing switching power supplies and rotary encoder measurements.

1GSa/s Real-time Sampling & 25GSa/s Equivalent-time Sampling
|
|
1GSa/s Real-Time Sampling allows measure high frequency signals accurately. A higher sampling rate helps to acquire more waveform data in a short period of time. It is especially useful for the single-shot (non-repetitive) waveform capture and observation as the faster the waveform data can be acquired the better the waveform reconstruction. For repetitive signals, however, Equivalent-Time (ET) sampling is a better tool than Real-Time Sampling. ET sampling is able to acquire data periodically, with each successive sample increasing the sampling points. By acquiring data from repetitive waveform cycles, ET Sampling Technology accurately reconstructs the waveforms at a resolution of up to 40ps. The GDS-2000 Series is able to sustain a 25GSa/s sampling rate for repetitive waveform acquisition and reconstruction compared to a Real-Time Sampling capability of 1GSa/s rate.

TFT Color LCD Display
|
|
|
|
For a crisp and clear view, the GDS-2000 Series has a color TFT LCD display. Compared to STN displays, TFT panels have reduced flicker, wider viewing angles and brighter color reproduction. With support for displaying 4 waveforms, measurement grids and signal data at the same time, a bright, clear, colored screen is a necessity for comparing and analyzing data.
|
|
|
|
27 Automatic Measurements
|
|
|
|
The GDS-2000 DSO Series employs a comprehensive set of automatic measurement features. The automatic waveform measurement feature includes 27 frequently used measurement items grouped into three sections : Voltage, Time (Frequency), and Delay. A maximum of 10 measurement results can be shown on the screen and updated in real-time. These automatic measurement features are an effective way to monitor the characteristics of a signal in real-time. 19 automatic
measurements can be shown on screen simultaneously.
|
|
|
|
Go/NoGo Testing
|
|
|
|
The Go/NoGo testing function checks whether an input signal violates a user-defined template. Setting the template is a simple two -step process. Select a reference waveform from an input signal or waveform file and configure the violation tolerance from the reference waveform. After setting the template, Go/NoGo testing is ready to go. The GDS-2000 Series compares the input signal with the template in real time and shows the test result on the screen. Both the type of
Go/NoGo violation and the reaction to a violation can be configured to meet various application requirements. Any Go/NoGo violations are indicated either by an internal buzzer or by sending a control signal to an external device via the Go/NoGo BNC output on the rear panel.

|
|
On-Line Help And Multi-Language Support
|
|
|
|
For hassle-free operation, the GDS-2000 Series provides a built-in help manual via the Help key. Press the "Help" button to get into the on-screen Help mode, and then press any key to display instructions about that key's function on the screen. The GDS-2000 Series interface menu and the on-screen Help have multi-language support. Supported languages include: English, Russian, Spanish, Korean, German, Japanese, Traditional and Simplified Chinese. This provides
localized help if English is not your preferred language and offers an easy environment for multicultural joint-projects. In the future, GW Instek will increase the number of languages to provide broader localized support for languages that are not currently supported.

|
Data Storage & Transfer And USB Printing Support
|
|
|
|
20 sets of waveform data, 20 panel setups and 4 reference waveforms can be saved into internal memory to be recalled later for display. All the waveform data, panel setups and screen images can be saved to a USB flash drive.
With optional PC software available for download on the GW Instek web site, the GDS-2000 series can be remotely controlled.
The software can also monitor and record waveform data over a period of time by continually transferring data to a PC for further analysis. The GDS-2000 Series supports printing directly to a USB compatible printer. Screen images can be printed in either color or grayscale depending on the printer settings.

|
Battery Power Operation
|
|
|
|
With the optional Li-ion battery packs, the GDS-2000 Series market coverage is extended to field application areas where AC power is not available. Fully charged, the two light-weight battery packs keep a GDS-2000 DSO running under normal operation for over 3 hours.
The built-in battery charger automatically recharges the battery packs whenever the oscilloscope is connected to AC power. An optional soft carrying case (GSC-005) is available to accommodate field applications.
