OM-06-320 REV E - i - 99-500-001 SRI/PMD SERIES 300 DIGITAL TELEMETRY SYSTEMS A BRIEF INTRODUCTION With over 25 years of experience in the field of industrial and commercial telemetry systems, SRI/PMD stands as an industry leader in providing an efficient means of transporting measurement data from one location to another. The use of Wireless Link    technology allows these systems to be utilized to obtain information from hard to get to locations, or from places where it is simply inconvenient and/or insecure to run hard wired interconnects. With the advent of our newest Series 300 Digital Telemetry Systems , we have released the power of Digital Signal Processing into what was previously a purely “analog” marketplace. The use of all digital signal processing not only furnishes a more robust and versatile means of gathering, transmitting, processing, and outputting highly accurate measurement data, but it also provides this capability at a cost affordable for even budget conscientious consumers. In developing the Series 300 systems, SRI/PMD has taken technology developed for highly critical space telemetry applications and applied it to designs suited for a wide variety of applications here on earth. Whether your particular need is gathering real-time torque, pressure, or temperature data from large industrial equipment, or is more simply oriented toward sending a basic analog signal across a parking lot, we believe you will find the right solution to your requirements at a price far below what has previously been offered.

5.0TEST SAMPLE SETUP AND CONFIGURATIONS The Summation Research, Inc. Series 300 Digital Telemetry System was placed on the nonconductive 80cm high manual turntable. The unit was configured with an external AC/DC power supply and a 9 VDC battery. Cables were configured in a normal setup. Setup for the Series 300 Digital Telemetry System is shown below. The Series 300 Di gita l Telemet ry System test setup is shown in Photos 1 and 2. JA-1679 11 JA-1679 12 PHOTO 2 JA-1679 13 6.0PROCEDURES AND RESULTS 6.1Radiated Emissions Prescans were done in a shielded enclosure and are on file at Rubicom Systems. There were no signals detected from the transmitter below 903.3MHz. Tabulated data for all signals detected are listed in this section. Table 6.1-1 presents receiver frequencies within 10dB of the requirement and Table 6.1-2 through 6.1-7 presents transmit harmonics. Tests for transmitter harmonics were done at low, mid and high frequencies (903.3MHz, 912.3MHz and 921.3MHz). All testing from 30MHz to 10GHz was performed on the 3 meter site. An example of calculations are as follows: Meter Reading 20 dB
V Antenna Factor +16 Conversion Factor Cable Loss +2 Correction Factor Result +38 dB
V/m The spectrum analyzer memory card contains the correction factors for calibrated cables and antenna factors. When external attenuation is required the reference level is offset during test. Data Sheets 6.1-1 through 6.1-16 present plots of the radiated data over the range of 30MHz-10GHz. The exact levels of signals detected and maximized are presented in the tabulated tables mentioned above. Data Sheets 6.1-17 through 6.1-32 are the ambient profiles for the 30MHz- 10GHz radiated measurements. JA-1679 14 6.2Conducted Emissions Power line conducted data is presented in Data Sheets 6.2-1 and 6.2-2. No failures were experienced during conducted testing. No modifications were needed to meet conducted emission requirements. JA-1679 15 FCC RADIATED EMISSIONS TABULATED RESULTS EUT MODEL: Summation Research, Inc.
