ELECTRONICS: Saelig Company Inc. announced new features for the PDS5022S low-cost, full-featured 25MHz two-channel bench top oscilloscope. The new features are: Auto-scale, FFT, and trigger hold.
Autoscale can be set to 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 in the same manner as ‘AutoSet’, but instead of being a one-time function, it’s active until turned off, keeping the hands free.
FFT allows you to instantly see the frequency spectrum of the signal under test.
Trigger Hold allows you to introduce a delay relative to the trigger point so that a different part of the signal can be seen.
Low-cost 2-channel PDS5022S is packed with useful features normally only seen on higher-end DSO’s: video trigger, auto-measurements, large 8 full color LCD display, 100MS/s sampling, XY Mode, auto- set, averaging, math functions, USB output, waveform storage, 3 year warranty, etc. PDS5022S 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. PDS5022 offers on-board storage, and USB output, making the PDS series the ideal choice for design, maintenance and lab use. PDS5022s features include: manual cursor measurements, up to 5 automatic measurements, high-speed screen update, storage for up to 4 waveforms & set-up parameters, 6KBytes/ch memory, convenient serial interface with software, 400V (dc+av peak) maximum input, optional rechargeable Battery Pack, etc.
This lightweight scope is perfect for any engineers or students desk. USB connection makes printing stored results easy too. With a large 7.8 640 x 480 color LCD, PDS5022S is small enough and light enough to carry anywhere you need. With a buffer size of 6K samples, PDS5022S sampling range is 10Sa/s to 100MSa/s with synchronous 8-bit sampling on both channels. Sensitivity range is 5mV/div~5V/div with maximum display of ±50V. Another really useful feature is the ability to store 4 waveforms for comparison with live inputs. A persistence control is available too which simulates old analog scopes to compare slow-moving waveforms with previous scans. X-Y display allows you to see phase changes. A+B and A-B math capability is also included.
There is currently much discussion around the term "platform," which may be preceded by the adjectives "mobile," "wearable," "medical," "healthcare," etc. However, regardless of the platform being discussed, they usually have one key aspect in common: They tend to be wireless. So, why is this one aspect so fairly universal? The answer is convenience.
Everyone has a MEMS story. For most of us it’s probably the airbag that saved our lives or the life of a loved one. Perhaps it’s the tire pressure sensor that alerted us about deflation before we were stranded alone on a dark muddy road.
Bioimimicry is not merely a helpful design tool -- it also encourages designers to think not only about how to solve design problems by imitating nature, but how to make the products, materials, and systems they design more ecologically sound and nature-friendly.
