Saelig – New low-cost and versatile 30MHz oscilloscope (SDS5032E)Aug 21 2012 - Test & Measurement [More Test & Measurement Articles]
Saelig has announced the SDS5032E – a new, low-cost two-channel oscilloscope which is packed with useful features normally only seen on higher-end DSOs, including external and video-capable triggering, auto-measurements, auto-scaling, a large 8-inch high-resolution full-colour liquid crystal display, XY mode, auto-set, averaging, math functions, USB output, waveform storage and pass/fail output. FFT functionality is included for frequency spectrum display, in addition to a built-in 6-digit frequency meter, which can measure frequencies from 2Hz to 30MHz.
The Autoscale feature can automatically adjust 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 functions like AutoSet, but instead of being a one-time function, it’s active until turned off, allowing ‘hands-free’ measurements. The FFT function shows an instant frequency spectrum of the signal under test, while the Math function shows the results of the addition, multiplication, division and subtraction operations between Channel 1 and Channel 2, and the FFT operation of Channel 1 or Channel 2.
The SDS5032E 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 with triggering on NTSC/PAL/SECAM line or field waveforms.
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 serial interface with PC software, and advanced trigger settings including pulse width criteria for detecting rogue signals.
This lightweight (3.3lb) and compact 13.7 × 6.7×3 inch oscilloscope comes in an attractive slim case and 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-inch 800 x 600 colour TFT-LCD, this scope is small enough and light enough to carry anywhere. Sensitivity range is 5mV/div to 5V/div, with horizontal display of 4ns/div~100s/div. An external VGA output port allows the screen information to be displayed on a computer monitor or projected with a video projector. The SDS5032E offers on-board storage, and USB output, making it ideal for use in education, design, maintenance and lab applications, says the company.More news from Saelig
