Portable FFT Spectrum System utilizes Palm(TM) handhelds.

Press Release Summary:



Model DAS-1257 12-bit spectrum and data acquisition module tests vibration and power using Palm handheld. It has 4 analog channels and 1 digital counter input channel. When combined with Connection Wave software and Palm Tungsten T handheld, system permits FFT waveform displays of 512 points across 5 kHz bandwidth running 1 channel, from sensor plugged into DAS-1257. Close-up view of any part of FFT waveform can be analyzed using built-in Zoom feature.

Datastick Systems Announces First Integrated Portable FFT Spectrum System on Palm(TM) Handhelds



New Datastick DAS-1257 spectrum and data acquisition module with Datastick Connection Wave software

SANTA CLARA, CA, OCTOBER 21, 2003 ­ A lightweight, portable FFT analysis system for testing vibration and power on Palm handhelds was announced today by Datastick Systems, Inc.'s Vice President of Marketing Michael Scandling at the Instrumentation Society of America ISA Expo 2003 in Houston. The system is being demonstrated in Datastick's booth 1609.

The new 12-bit DAS-1257 spectrum and data acquisition module for Palm handheld computers has four analog channels and one digital counter input channel. The DAS-1257 and the new Datastick Connection Wave software, when combined with most Palm Tungsten T handhelds, permit FFT waveform displays of 512 points across 5 kHz bandwidth running one channel, from a sensor plugged into the DAS-1257.

The DAS-1257 system with Datastick Connection Wave is ideal for portable test and measurement and compliance reporting applications in environmental, industrial, R&D, field, and lab settings, including vibration and power analysis.

The DAS-1257 system is extremely versatile, running in any of three modes:
o Low-speed real-time display (up to 20 samples per sec) general-purpose data acquisition with Datastick Connection or Datastick Connection Plus software.
o Moderate-speed (up to 400 samples per second) time-based data acquisition with Datastick Connection Pro software.
o FFT display of 512 points across 5 kHz on a single channel with Datastick Connection Wave software using a Tungsten T/T2/T3 or Tungsten C handheld.

"Combined with the Palm handheld, this extremely portable system, excluding sensors, weighs only 10 ounces, fits in a pocket, and there's no laptop to carry. Measurements can be taken and displayed in ways not before possible on handhelds, and at a significant cost savings," said Scandling.

Once acquired, a close-up view of any part of the FFT waveform can be analyzed utilizing Wave's built-in Zoom feature. The Inspect tool, operated by moving the cursor, provides a numerical readout of any specific data point on the waveform.

A wireless version of Datastick Conection Wave was introduced in June by Datastick and its partner Oceana Sensor Technology. Datastick Connection Wave BT for ICHM 1.0 utilizes the Palm OS® Bluetooth(TM) extensions for communication with Oceana Sensor's Wireless e-Diagnostics(TM) System Products and enables Oceana Sensor Technology's ICHM® 20/20 to display acquired high-speed sensor data on wireless handheld devices running the Palm OS. It is being demonstrated in Datastick's booth 1609 and in Oceana's booth 1136.

Datastick Systems, Inc., designs and develops cost-effective handheld test and measurement products for a broad range of industrial, scientific, governmental, environmental and educational markets. Datastick developed the first general-purpose data acquisition hardware and software system for the Palm platform. Datastick is located at 275 Saratoga Avenue, Ste. 160, Santa Clara, CA 95050.
