Dual-channel RF Power Meter
The 4730 series RF power meters include the first CW power meters with dual-channel capability in a VXI configuration and offer two of the fastest power meters in the world with the ability to sample up to 200 readings per second. The power meter can measure CW power on one channel or both, depending on how the user sets up the instrument. Peak power can be calculated by entering the duty cycle and the meter's dial channels, and built-in math processing capability provides simultaneous input and output power measurement capability. Price: $3000 (model 4731 single-channel meter) or $3750 (model 4732 dual-channel meter). Delivery: four to six weeks (ARO).

Minimum Loss Transistor Test Fixture
This minimum loss transistor test fixture (MLTF) is a low loss test fixture as required for sub-1 W load pull measurements of packaged high power RF transistors. The low loss is obtained by exclusively using air as dielectric. The test fixture can be used up to 5 GHz and includes a main body with coaxial connectors and connector flanges as well as a set of TRL calibration standards and measurement inserts (one set per transistor package type).

Cable and Antenna Analyzer
The S251B SiteMaster hand-held broadband cable and antenna analyzer performs antenna-to-antenna isolation and LNA/tower-mounted amplifier (TMA) testing and accurately solves transmission, cable and antenna problems. The S251B is well suited for field technicians and installation/maintenance crews of service providers who must perform verification of cables, antennas, TMA and duplexers as well as measure antenna-to-antenna isolation in the GSM 1800/PCS 1900 and analog cellular markets. Operating over the 625 MHz to 2.5 GHz frequency range, the S251B has a five-segment limit line that provides multiple limit segments within the same display. Selectable display resolution of 130, 259 and 517 data points provides flexibility, measurement speed and significantly improves distance-to-fault measurement capability up to "e 1000 meters. Price: $9800.

Internet-ready Spectrum Analyzer
The model P9116 full-featured spectrum analyzer system covers the 100 kHz to 1600 MHz frequency range and is packaged in a rugged industrial chassis that includes a power supply, Pentium controller, modem and various serial and parallel communication ports. When used in conjunction with a VGA monitor and the supplied graphical user interface, the unit can be operated as any other conventional RF spectrum analyzer. Since the unit's synthesized LO is digitally tuned, the precise number of steps and the span between steps are fully controllable with a resolution of 2 Hz across the entire spectrum. This feature, coupled with the synthesizer step time of < 150 ms, makes the unit most suited for analyzing typical RF communication signals.
Morrow Technologies Corp. (MTC),
The HP E4406A VSA series transmitter tester offers a good combination of speed and accuracy for making cdmaOne and GSM transmitter measurements. The standard-compliant, one-button measurements for wideband CDMA and cdma2000 help engineers develop third-generation (3G) products quickly and confidently. The HP E4406 A is designed to increase productivity in the development stages of 3G products and give engineers confidence in test results. Price: $27,800. Delivery: three weeks (ARO).

ATS Probing Station
The model 2245 automatic test system (ATS) probing station is engineered specifically to accommodate delidded device under test (DUT) probing with ATS from multiple manufacturers. By allowing the probing platform and ATS to remain in very close proximity, DUTs may be probed at full test speeds without the need to reprogram standard test vectors to allow for cabling delay. A two-operator platform allows stable and convenient user access to the work area. To accomodate operator preferences, the video-enhanced, motorized microscope is joystick and software program positionable. The model 2245 accommodates ATS from Hewlett-Packard, IMS, Schlumberger and Teradyne.

Weather/Windshear Radar Test Set
The model WRT-100 lightweight, battery-operated radiating weather and windshear tester provides coherent far-field responses to radar transmissions and simulates weather, turbulence and windshear to determine radar system capability to properly display hazard warning conditions, verify crew reports and reduce no fault found returns. In addition to measuring and storing such parameters as peak power, pulse width, pulse repetition frequency, scan time and side lobe levels on a PCMCIA card, the test set is also capable of receiving and recording antenna patterns for evaluation of radome performance. The WRT-100 is specifically designed to interface with the AlliedSignal RDR-4B and the Rockwell Collins WXR-700X weather and windshear predicting radars.
MPD Technologies Inc., MPD & Republic Products,
Programmable Fiber-optical Delay Line
This programmable fiber-optical delay line covers the 2.25 to 2.55 GHz frequency band and can be set to a four-bit resolution using an internal microcontroller. A low loss switching network allows the user to select different lengths of optical paths using computer control while minimizing insertion loss and crosstalk between paths. The paths increase in delay time in 1.25 ms increments, accounting for a total delay of 18.75 ms. Intended for radar testing, cellular base station multipath fading test and RF memory applications, the delay line offers long delay, high dynamic range and insensitivity to change of frequency and other environmental factors. Custom delay lines up to 10 GHz are also available.
