Digital Oscilloscope

LeCroy LT224 / LT322 Waverunner Digital Oscilloscopes : The LeCroy WaveRunner™ series of digital oscilloscopes offer powerful tools at reasonable prices. WaveRunner oscilloscopes feature a user interface that is simple to learn and use, making it easy to take advantage of the scope's unique capabilities. SMART Trigger and SMART Memory let you capture signals while maintaining the maximum resolution and accuracy. The large, crisp 8.4" TFT flat display with analog and color-graded persistence makes it easy to view and measure signals, as well as locate rare signal problems. All models include automatic measurements, waveform math functions, and analysis capabilities so you can average sweeps, enhance vertical resolution, and use FFT to view a signal's frequency spectrum.
Features: • LT224 - 200 MHz, 4 Channels • LT322 - 500 MHz, 2 Channels • 200 MS/s Single Shot Sample Rate • 100 kpoints/Ch Record Length • 8.4" TFT Color Display • Analog Persistence™ • SMART Trigger® • Averaging and Enhanced Resolution • Math Analysis with FFT • Parameter Measurements • Pass/Fail Testing • Channel Deskew
Engineering Units • Internal Floppy Drive • GPIB, RS-232, Centronics, and VGA Ports • Internal Graphics Printer, Hard Disk Drive, and Memory Card Options

200 MS/s Digital Storage Oscilloscope : These digital scopes store waveforms in memory. For one-shot events, you can see what happened before the trigger. You can store up to two waveforms, each 2kx8 bit long. After acquisition, the data can be manipulated and displayed in many different ways. You can change time base or vertical position. You can select which portion of a waveform you'd like to look at in more depth. You can compare the measured waveform to a "known-good" waveform in memory. Additionally, Model 5105A incorporate glitch capture to see signals that otherwise would not be seen. You can interpolate or smooth the wave form to "fill in the gaps."
Features: • Selectable acquisition modes • REFRESH: Trace is updated left to right. • Display may show only part of record • ROLL: adds new sample to right side of display. Display always shows what's changing. Useful for slow moving signals. • SINGLE to store one shot event for analysis • PRETRIG to see what happened before the trigger • ENVELOPE to see how signal fluctuates • GLITCH CAPTURE for short duration voltage "spikes" • On-CRT readout for ease of use. Works in both analog and digital mode. • Set cursors or have scope automatically take measurements • Linear, sinusoidal interpolation: Fills in digital dots between two samples. Good for digital expansion. • Analog smoothing: Fills gap in an analog manner between two adjacent display dots.

PCI-42X/43X Digital Oscilloscopes : This product line consists of the PCI-421, PCI-422, PCI-423, and PCI-425 Single Channel Digital Oscilloscopes and the PCI-431, PCI-432, PCI-433, and PCI-435 Dual Channel Digital Oscilloscopes. Each oscilloscope in this product line has the capability to capture transient waveforms and also has an Equivalent Time Sampling (ETS) circuit that extends the equivalent sampling rate to 200 Gigasamples/second (GSPS) when acquiring repetitive signals. This extraordinary 5 picosecond equivalent sampling is unmatched by any card-based oscilloscope in the world and in most cases outperforms the sample rates found on box-based oscilloscopes costing 5 to 10 times more money. Each oscilloscope in this product line fits into the ISA expansion slot of a PC, and features seven vertical voltage ranges, AC/DC coupling, offset control, and timebases from 500 ps/div up to 200 ms/div. Bandwidths for the product line range from 100 MHz to 300 MHz.

Low-cost digital oscilloscope with colour display : In addition to a colour display, the new Tektronix TDS2000 series offers up to 200MHz bandwidth coupled with high sampling speed, a choice of two- or four-channel models and many new features. Apart from improving the instruments' aesthetic appearance, the colour display and intuitive user interface translate into improved productivity for the user. The fact that each active trace is presented in a unique colour saves time, especially when three or more waveforms are displayed, by making it easier to distinguish waveforms at a glance. Associated screen readouts and front-panel controls are similarly colour-coded for easy control and accurate interpretation. TDS2000 oscilloscopes feature 11 automatic measurements as standard, including rise-time and fall-time, frequency, RMS and peak-to-peak values. In addition, on-screen cursors can be used to make manual measurements. In both cases, the measurements are linked to the channel colour to improve visual clarity of the data. Both two- and four-channel models have an external trigger input, so that all input channels can be used to capture and compare useful waveform information whilst triggering the instrument from a known source. A trigger view feature can be invoked to verify the characteristics of the trigger source. Whatever the source, a high-resolution digital frequency counter displays the trigger frequency on-screen. Prices for the TDS2000 Series start from GBP 995.

High Resolution PC Oscilloscope / Spectrum Analyzer : The ADC-212/3 balances resolution, sampling rate, and cost to make an ideal general purpose oscilloscope. The 3MS/s sampling speed and 32k waveform buffer makes the ADC-212/3 an ideal solution for high speed data acquisition / logging. The 12-bit resolution in the Y-axis gives the ADC-212/3 the ability to detect changes as small as 0.024 per cent. Conventional 8-bit oscilloscopes only have the ability to detect changes greater than 0.4%, but precision analogue and audio engineers require the ability to detect signal changes of less than 0.1 per cent. Most digital storage oscilloscopes have front end amplifiers designed for high bandwidth, these products are no exception. Unlike most oscilloscopes however, the front end amplifiers also exhibit very low levels of noise and distortion. This low noise and distortion, combined with the 12 bit resolution gives an 80dB dynamic range for the spectrum analyser.
