Description:

GDS-800 Series DSO is designed for and built to meet the demands of a modern Digital Storage Oscilloscope in today's mainstream market. Featuring color or monochrome LCD displays, 125k points of memory, and 25GSa/s equivalent-time (ET) sampling rate per channel, the GDS-800 Series provides a good balance between memory depth and sampling speed. With RS-232C, USB, Go/NoGo, standard printer port (excluding GDS-806/810), and optional GPIB interface, the GDS-800 Series is remarkably adaptable. The easy-to-remember menu tree, the analog-scope like front panel design, the advanced trigger functions including Pulse Width, TV Line, Event and Time-Delay make the general purpose GDS-800 Series able to meet the rigors of most signal measurement requirements in the market.

FFT FUNCTION

 

With the FFT function, the GDS-800 Series can easily transform the signal display from time domain into frequency domain. Most remarkably, the GDS-800 Series is able to display a signal in the time domain and frequency domain at the same time. The cursors under the FFT mode can indicate the frequency and voltage values as well as the relative values of △frequency and △voltage.

All these measurement readings can be simultaneously shown in the display.
 

25GSa/s ET SAMPLING RATE AND 125k MEMORY
The GDS-806/810/820/840 Series, with superior sampling rate up to 25GSa/s, provide 40ps point to point resolution for displaying repetitive waveforms. With 125k points long memory, the GDS-800 Series provides higher or equal sampling rate and longer record length for the signal observation.

In general, under the same time base setting, the longer memory a DSO has, the higher sampling rate it performs. This is one of the reasons the GDS-800 Series can always give a better waveform display than oscilloscopes with short memory.
 
12 DIVISION HORIZONTAL DISPLAY
 
The on-screen menu of a DSO makes the operation easier, but it also limits the space for waveform display. The GDS-800 Series offers users with an alternative to view the waveform in 12 divisions by hiding the on-screen menu when it is not used.

Simply through a button press, the display becomes available for 12- division waveform. Press the button again, and the display goes back to normal. This is a very useful feature when users expect to view a longer portion of the signal under test.
 
FREQUENCY ADJUSTABLE PROBE CALIBRATION SIGNAL
 
The probe calibration signal in the GDS-806/810 is frequency GDS-800 Series adjustable from1kHz to 100kHz in 1kHz step, and duty cycle adjustable from 5% to 95% in 5% step. The probe calibration signal is provided mainly for accurately running probe compensation, but is also adequate to be used as a signal source for education and basic testing purpose. (This function is only available in GDS-806/810 Series)
 
15 AUTO MEASUREMENTS AND SIMULTANEOUS T/ V CURSORS
 
The 15 Auto Measurement functions in the GDS-800 Series enable users to easily measure the most frequently tested parameters of signals.

The GDS-800 Series are able to display 10 auto measurement data on the screen for two channels at the same time. Users will be able to get all their measurements results at a glance.
 
ADVANCED TRIGGER FUNCTIONS
 
The GDS-800 Series provides advanced trigger features such as TV line trigger, video trigger, pulse width trigger, event delay trigger and time delay trigger, which could only be found in a higher-end GDS-800 Series. The advanced trigger capability of the GDS-800 Series makes the waveform capture in a broad range of applications possible.
 
ON-SCREEN HELP MANUAL
 
The On-Screen Help Manual allows users to get a real-time help whenever they need to know the details of any function key. Press the"Help" key first, then press any other function key on the front panel, the On-Screen Help contents for that specific function key will appear in the display.
 
AUTO SET-UP SEQUENCE
 
The Auto Set-Up Sequence enables testing engineers to carry out ATE tests without complex software programming. After users program a sequence from the front panel, the GDS-800 Series starts performing the measurements step by step according to the sequence until completion. The ATE test cycle can be programmed to repeat for a number of times.
 
VERSATILE INTERFACE
 
The GDS-800 Series provides various kinds of interface including RS-232C, GPIB, USB, and printer port. With a software designed specially for USB communication, the GDS-800 Series enables users to view nearly synchronous waveform displays on both PC screen and the GDS-800 Series.
