Saelig Debuts New Low-cost 300MHz Oscilloscope With Deep Memory

The SDS9302 is a low-cost versatile scope that is packed with useful features normally only seen on higher-end DSOs, including deep memory, external video-capable trigger, auto-measurements, auto-scaling, large 8 full color TFT LCD display, external monitor/projector output, XY mode, auto-set, averaging, math functions, USB output, waveform storage, pass/fail output and a 3-year warranty. Even FFT functionality is included for frequency spectrum display.

The Autoscale feature automatically adjusts the vertical gain, or the horizontal time base, or both together. This is useful for circuit probing - as the probe is moved from point to point on a circuit board, the display auto-adjusts for best trace presentation. It works like AutoSet, but instead of being a one-time function, it's active until turned off, keeping hands-free. An instant display of the frequency spectrum of the signal under test is provided with the FFT function.

The SDS9302 can automatically measure and display frequency and peak-peak/rms/mean values, but cursors can also be moved to make individual readings. A built-in self-calibration facility improves measurement accuracy. Video monitoring is also possible since you can trigger on NTSC/PAL/SECAM line or field waveforms. SDS9302 features include: manual cursor measurements, up to 19 automatic measurements (including frequency), high-speed screen update, storage for up to 15 waveforms and set-up parameters, convenient USB interface with PC software, 400V (DC+AV peak) maximum input, optional rechargeable battery pack, and multi-language capabilities.

The lightweight SDS9302 oscilloscope is perfect for any engineer's or student's desk. The USB master and slave connections make printing or storing results easy too. With a large 8 800 x 600 pixel color TFT LCD, this scope is small enough and light enough to carry anywhere, weighing under 4 lbs.

Sensitivity range is 2mV/div to 10V/div with maximum display of ±100V; horizontal display is from 1ns/div to 100s/div. Up to 15 waveforms may be stored internally for comparison with live inputs. Another useful feature is that waveforms can also be stored on plug-in USB memory sticks. A persistence control is also available which simulates older analog scopes to compare slow-moving waveforms with previous scans. 'A+B' and 'A-B' math capability is included, while the X-Y display feature reveals phase delays.

The SDS9302 offers on-board storage, and USB output, making it an unbeatable value for use in design, maintenance and lab applications. Made by specialist test and measurement manufacturer Owon, it is available now from stock at only $1499.95 from Saelig Company Inc. Pittsford, NY.
