GSA Schedule

Our PAMS and SG1000/PR1000 test equipment are available at prenegotiated prices through our GSA contract GS24F0035M.

Power Detectors
Praxsym manufactures a series of unique power detectors which are ideal for use in applications where an RF signal modulated by a complex waveform is to be detected over a wide dynamic range (e.g. CDMA and WLL systems). These detectors respond to input power level changes linearly (mV / dB). Unlike conventional log detectors, these power detectors exhibit no modulation errors.

Synthesizers
Our synthesizers are complete assemblies that include their own low phase noise references. Many models are available covering many of the major communications bands. In addition, some clock-multiplied upconverters are available for satellite communications where ultra-low phase noise is critical to system performance.

OEM Modules
Much of the technology which Praxsym's engineers have developed to solve our customer's problems is available as a sub-assembly for use in other systems. These modules include GaAsFET bias boards, automatic leveling controls, and synthesized upconverter boards.

Test Equipment
Praxsym also manufactures application specific test equipment.  We have a complete line of RF Shielded Enclosure certification and maintenance products.  Our PAMS equipment allows a technician to easily and efficienctly measure pathloss and shielding effectiveness of an RF Shielded Enclosure.  The SG1000A/PR1000A high powered signal generator and low noise preamplifier combination are integral parts of an RF Shielded Enclosure certification system which meets NSA 94-106 standards.  Finally, our SEITS system can be used as a complete tool for troubleshooting alternate ground paths between an isolated ground installation and the surrounding building ground network.

Praxsym also has a diverse line of test equipment for commercial applications.  Our PathTrax Transmitter and Receiver combination is a system designed for making signal strength, pathloss or shield level measurements.  We make Dual Band Test Transmitters and Receivers which are available in different combinations of bands as in-building site survey tools.  Our PM-2458 Broadband Wireless Power Meter is a low-cost, handheld tool for 2.4GHz, 5.3GHz and 5.8GHz wireless applications.  It measures forward power, reflected power and VSWR.
