Pittsford, NY, USA: Saelig Company, Inc. announces two new benchtop scopes – PDS8102T and PDS8202T, both offering a huge 2M data point record length, which allows great depth for investigating fast, intermittent pulses . These low-cost 2-channel scopes sample at 1 Gsa/s and 2 GSa/s respectively, and are packed with useful features normally only seen on higher-end DSOs including video trigger, auto-measurements, large 8″ full color LCD display, XY Mode, auto-set, averaging, math functions, USB output, waveform storage, 3-year warranty, etc. Even FFT functionality is included for seeing spectrum information, as well as Autoscaling and Trigger Holdoff.

• Autoscale 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 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.

PDS8102T and PDS8202T 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. PDS8102Tand PDS8202T offer on-board storage, and USB output, making the PDS series the ideal choice for design, maintenance and lab use. PDS8102T and PDS8202T features include: manual cursor measurements, up to 5 automatic measurements, high-speed screen update, storage for up to 4 waveforms & set-up parameters, convenient serial interface with software, 400V (DC+AV peak) maximum input, optional rechargeable Battery Pack, etc. They have multi-language capabilities too!

These lightweight scopes are perfect for any engineer’s or student’s desk. USB connection makes printing stored results easy too. With a large 7.8″ 640 x 480 color LCD, these scopes are small enough and light enough to carry anywhere you need. 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.

Resembling much more expensive look-alikes, PDS8102T and PDS8202T offer unbeatable value and are available now in stock from Saelig Company Inc. Pittsford NY.

MILPITAS, CA – August 16, 2010 – Linear Technology introduces the LTC5587, an industry first 40dB dynamic range 6GHz RMS detector integrated with a high sampling rate 12-bit serial A/D converter. The digital output RMS RF detector provides +/-1dB measurement accuracy of high crest-factor signals, independent of the modulation used. The detector is capable of operating over a wide frequency range from 10MHz to 6GHz. The integrated 12-bit ADC captures and digitizes the detector measurement at a rate of up to 500k samples/second and delivers the data via a bit stream over a serial SPI port. The RF detector operates with single-ended input and requires no external balun transformer. Its small 3mm x 3mm DFN package provides a highly compact solution.

The LTC5587’s +/- 1dB accuracy over a 40dB dynamic range and over the full temperature range from -40°C to 85°C offers best-in-class performance. Combined with a 12-bit A/D converter, the device provides 0.014dB per bit measurement resolution. Its low power consumption is ideal for applications in cellular basestations, picocells, and femtocells supporting all standards including LTE, W-CDMA, TD-SCDMA, CDMA/2k, GSM/EDGE and WiMAX. Other applications include MIMO radios, repeaters, point-to-point microwave links, military radios with complex modulation, remote power measurements, and portable test and measurement instruments. The detector is particularly useful in FPGA-based systems where no A/D converters are available.

The LTC5587 is powered from a single 3.3V supply. During sampling mode, its total operating current is 3mA, consuming only 10mW of power. Its consumption is further reduced by one-half when the ADC is idled, making the LTC5587 suitable for battery powered or portable remote RF measurement systems. The device also has shutdown capability, drawing less than 10uA supply current when disabled. The LTC5587 is offered in a small 3mm x 3mm 12-pin DFN package, providing a compact solution footprint. The LTC5587 is available from stock, priced starting at $5.17 each in 1,000 piece quantities. For more information, visit http://www.linear.com/5587.
