1 W Portable Transmitter
The Lizard series portable, battery-powered 1 W CW stimulus transmitter is designed for indoor coverage testing. The unit is suitable for local area network setup and for evaluating network performance. In a typical application, one or more transmitters are placed throughout an area of interest and set on different channels while measuring and recording field strength.

Power and SWR Meter
The model FIT 1700 fast-installation tester covers the frequency band from 1700 to 2000 MHz and is designed to check mobile telephones in GSM and PCS1800/1900 networks. The RF power range is from 2 mW to 5 W with an accuracy of better than 1 dB. The separate RF head is inserted without long interconnection cables between the transmitter output of the mobile radio and antenna cable, thus avoiding additional measuring errors. The meter identifies automatically whether a CW analog RF signal or bursts from a cellular network are applied. The storage of maximum and minimum values permits the detection of intermittent faults. In case of a short circuit in the antenna or antenna cable, a red light-emitting diode provides a warning.
Bahnhofstrasse, Grassau, Germany,
The model 600T open resonator has been fitted with a special sample holder for measurement of substrate materials and thin dielectric sheets. The unit features a demonstrated capability to measure e and tand of sheets as thick as 2 mils in addition to characterizing thick dielectrics under the instrument control of the company's CAVITY software package. The resonator operates from 15 to 90 GHz and offers a noncontacting method of measuring materials.
Portable Spectrum Analyzer
The model 2398 portable spectrum analyzer operates from 9 kHz to 2.7 GHz and is designed for use in the field or laboratory. The unit features a split-screen mode that offers simultaneous viewing of two display functions. Full market capabilities simplify signal troubleshooting. The standard RS-232 port and optional GPIB feature allow remote control of the instrument, and a parallel printer port supports many popular printers. Electromagnetic compatibility testing can also be performed using an option that provides the measurement capabilities and resolution filters required for precompliance screening. Price: $6495. Delivery: six weeks (ARO).
IFR Systems Inc.,
VXI Spectrum Analyzer
The model V9054 fully programmable spectrum analyzer is designed for use in versa module Eurocard computer bus extension for instrumentation (VXI) cellular production test systems. The 0.5 ppm frequency accuracy is accomplished via digital tuning that locks the synthesizer to the reference oscillator at each point in a sweep. Independent point markers simultaneously provide the absolute amplitude and frequency value of two points. A constant display of the delta values of these two points provides the user with an easy method of measuring power amplifier intermodulation distortion and other in-band and out-of-band characteristics of miscellaneous cellular RF components and assemblies. The synthesizer step time of less than 120 ms results in fast measurement speed, which directly affects product throughput. The 1.6 GHz analyzer has an amplitude range of -120 to +20 dBm with an absolute level accuracy of +/-0.5 dB.
Morrow Technologies Corp.,
Device Under Test Rotators
The 6100 series rotators are designed to accurately position devices under test, accommodate higher loads and provide a larger delivered torque without sacrificing accuracy. The units combine an improved rotating drive module with various housings and turntables to support a variety of measurement applications. The positioner components range from rotating and linear axis positioners to structural masts and arms with load ratings up to 200,000 lb. All motorized positioner axes can be interfaced to the company's standard controllers with a single cable per axis architecture.
Microwave Instrumentation Technologies LLC,
Automated Microwave Oven Test System
The model HI-2651 microwave oven automated test system is designed to minimize the time- and labor-intensive processes involved in microwave oven leakage measurement. The unit features interchangeable microwave probes (up to 24 per system), simultaneously displayed leakage values from all probes, and graphical and numeric display screens. In addition, front-panel control of all functions and front-panel status screens provide easy setup and analysis. Data logging is included for archival purposes. The system interfaces with an existing microwave oven production system to allow for fast data collection, measurement and fault analysis of newly manufactured microwave ovens.
