High Speed Sampling

The OScope captures single-shot data at 500MSa/s (every 2ns) 500MSa/S single shot sample rate on 1 channel with a 1 Million point buffer. 250MSa/S single shot sample rate on 2 channels with a 512K point buffer.

Advanced Triggering DSO

The DSO-8502 has advanced pulse triggering as well as standard level triggering.

Level Trigger Level trigger with rising or falling slope	Multi Trigger Trigger on multiple channels:
Pulse Width Trigger Pulse width. Trigger on a pulse of a certain width	Pulse Count Trigger Pulse count. Trigger on the Nth pulse

The oscilloscope has fully adjustable pre/post trigger position. This lets you define how much data is collected before the trigger event and how much is collected after.

Deep Acquisition Memory

1 Million point buffer on 1 channel at a sample rate of 500MSa/S. 512K point buffer on 2 channels at sample rates of 250MSa/S and below.

This is much longer than standard Oscilloscopes and enables you to capture more waveform details without sacrificing overall recording time. Longer data buffers give you the flexibility to use faster sample rates and still capture for extended periods of time.

“The big buffer really saved me. With my last oscilloscope I always had to balance recording time and time per division. With Link’s scope I can record at the fast sampling rate and still see the entire event.” Bob Mitchell, consultant. (beta tester)”

The Windows Oscilloscope software takes advantage of your computer's large color screen.

"zoom-and-scroll" simplifies trouble shooting and analysis. The display shows the entire recorded waveform(s). In addition, the user can zoom (up to 50X) on signal details and scroll through long data records to identify and characterize problems. The locked all-channel zoom keeps all the analog waveforms synchronized.

The deep memory allows analysis of jitter from the beginning of the record to the end. By zooming/scrolling and then measuring with cursors, pulse widths and channel-to-channel timing can be compared at different sections of data streams. This feature allows identification of time varying problems such as "power-on" sequences and clock jitter.

Channel History - Similar to Persistence mode, but much better.

The Oscilloscope software can automatically save and display previous captures.

• Each capture will be color coded based on time of trigger with the oldest ones fading to white.
• Up to 27 captures can be displayed simultaneously.
• Previous captures can be displayed by themselves, used with FFT, XY plot and Measurements.

Auto-Setup

With one mouse click the software will analyze incoming data and setup the oscilloscope using advanced data analysis routines. You can then fine tune any or all Scope parameters to your liking.

Spectrum Analyzer/FFT

• The DSO also delivers high accuracy spectrum analysis. A binary FFT algorithm is used to break the input signal into its frequency components
• Unlike swept spectrum analyzers which require a stable repetitive signal, the DSO-8000 can also analyze a single shot event
• You can control and view both the FFT (frequency-domain) and oscilloscope (time-domain) display windows simultaneously
• Two FFT channels can be viewed simultaneously.

• Spectrum analyzer frequency range, FFT algorithm, spectral resolution and vertical/horizontal size can be set via the software. This flexibility helps to optimize the spectrum analyzer for a particular application. The frequency range extends from DC to 250MHz (Max frequency varies with model and mode)
• FFT screen has its own set of cursors for magnitude and frequency readouts
• FFT data can be saved to disk and exported to other programs such as Excel, Mathcad, etc...
• Screen shots can be pasted into your documents

X-Y Oscilloscope plot

An X-Y Plot allows you to graph one channel vs. another.

Customizable Color Display

You can display any combination of Digital Oscilloscope and Spectrum Analyzer traces simultaneously.

Color can be a real time saver. Each display element can be a unique color. This includes each of the Data channels, Memories, Waveform functions, Horizontal cursors, Vertical cursors, Trigger position, Text, Background, Grid and more. We even color code the cursor measurements to the appropriate channel color.

Stand-alone oscilloscope display screens represent a compromise at best. Few people would choose a 7" or 9" monitor as the screen for their PC. So why use a small monitor for an oscilloscope? Link PC Based instruments let you choose the display monitor size and type for viewing your data. Plus, you can utilize powerful PC-industry display peripherals such as projectors, remote monitors, and heads-up displays. Many people are now using dual monitor PC's - our software will work there also - Imagine having a 30" wide trace window.

You can take electronic snapshots of the screen and put them into your documents as well as print data to your standard windows printer.

Fast, Accurate Measurements

Powerful cursors display voltage and time information Advanced waveform measurements are included with the FrontPanelTM software PASS/FAIL testing based on the results of those measurements is also available. Data can be logged to disk automatically on PASS or FAIL

Easy Installation

The PC Based oscilloscope connects to the USB port of your computer. To install the oscilloscope all you need to do is plug it into your PC, plug in the power supply and install the software.

The DSO is about the size of a video tape (7" x 3.75" x 1.5"). If you need portability what could be easier than connecting the DSO to your laptop?

Simple Operation

• Installation is a snap
• Make measurements in your first half hour
• Simple controls make operation intuitive
• All functions from one simple software "panel"
• Perform sophisticated operations that you couldn't even dream of doing with a knob based DSO
• Save default setups to disk for easy recall at a future date. You don't need to keep a notepad with settings scribbled in it. Just save them to the file name of your choice
• Data and settings are easily saved to disk - no extra software to buy - no communications upgrades
• Screen shots can be pasted into documents and annotated in your favorite image editing software

Battery power or wall power

Wall power
Most people will power their DSO-8000 series Oscilloscopes with the included wall adapter

Battery power
We have added a battery holder into the case that holds 4 AA batteries. Using AA batteries allows you to use the DSO away from a power source without draining your laptop's battery.

Automatic Data Storage

Superior to most stand-alone instruments, the DSO-8502 allows you to store an unlimited number of waveforms, timing patterns, and spectra to disk. Later, recall the data to the screen for visual inspection and comparison to "live" data, process the stored waveforms through our spectrum analyzer and waveform analysis functions, or use your own software to analyze archived waveforms.

To save time, you can automatically datalog your waveforms to your PC after each trigger. The data logger can also store only waveforms meeting specific parameter criteria, such as rise times between 20 and 30ns and pulse widths greater than 100ms, etc.... Data can be stored in our format or in industry standard format for exporting to other software.

FrontPanelTM Oscilloscope software supports Windows

OS's supported: USB 2.0 (compatible with USB 1.1) Windows Vista (Tested with Beta version of Vista) √ Windows XP √ Windows 2000 √

The DSO-8502 has software for Win XP, Win 2000 and has passed initial testing with Windows Vista. The oscilloscopes are PC Based and we regularly upgrade the software with more features and support for new operating systems. Software updates are free and available on the website.

Print Support

Waveforms can be printed on any Windows compatible printer.

Oscilloscope Probes

Two 1x/10x switchable probes are included with the oscilloscope.

We also sell the following types of probes:

• 1x/10x (2 meter cable)
• 100x
• Differential Probes

The speed of your PC does not significantly affect the performance of our instruments

Although we rely on the PC to display the data and for the user interface. We don't rely on it for our high speed data acquisition. If your PC is fast enough and has enough memory to run windows well it will run our products well also. All of the high speed data acquisition is done in DSO.

The Instrument has high speed samplers and data buffers. It can acquire data at up to 500MSa/s^*1 and stores the data in it's own 1 MegaSample*1 data buffer. When these buffers are full the data is transferred to the PC.

Software Libraries (optional)

The DSO-8000 series comes with FrontPanel for Win XP and Win 2K. We have done preliminary testing with Windows Vista beta versions and plan on supporting it when it is released.

But if you want to write your own software to drive the unit, our optional DLL or LabView drivers are available for purchase.

• DLL and LabView VI Library
