Military Microwaves Supplement
Kikusui Electronics Corp.'s model TOS5052 withstanding voltage tester is designed for use with electronic equipment or components and features a rise-time control that automatically increases test voltage to specified levels as required by UL-type and IEC safety standards. It offers a high capacity power supply with an output of 5 kV AC (max) at 100 mA. Preset output voltage, select output frequency of 50 or 60 Hz, digital voltmeter, ammeter and timer functions are standard. The tester provides dual-axis operation of the test voltage range selector switch and voltage setting knob and separate up/down keys to determine current and timer settings.
IFR Americas Inc.,
Portable CDMA Scanner
The Hummingbird portable CDMA scanner is available in both PCS and cellular models. It features low cost, speed, sensitivity and the ability to measure indoors or outdoors. The unit is self-contained and does not require GPS reception because it includes sync channel demodulation for positive base station identification and has removable data storage. Playback allows engineers to review problem spots with markers.
Berkeley Varitronics Systems Inc.,
Short Lead Transistor Test Fixture
The model MT950G short lead transistor test fixture includes short lead transistor inserts that are designed to work with the company's short lead transistor packages or similar package designs. The short lead fixture can work with the company's existing transistor inserts as well. The manual for the inserts contains circuit models, which can be used to develop de-embedding parameters.
Maury Microwave Corp.,
The model R3132/R3132N and R3162 spectrum analyzers are designed for high throughput wireless, RF and television production test applications. The instruments are competitively priced and equipped with a simplified user interface and automated measurements.
The models 901, 901R and 900 timer/counters provide state-of-the-art timer/counter mea-surements for time interval, frequency, phase and jitter. The model 901 has an ultra-high time interval resolution of 50 ps (single shot) and 1 ps (averaged), plus a speed of up to 8000 measurements per second. The frequency range can be extended from 300 MHz to 2.7 GHz. The model 901R is equipped with an atomic rubidium timebase frequency reference. The economy model 900 is identical to the model 901, except for a 250 ps single-shot time interval resolution, 225 MHz basic frequency range and a speed of 2000 measurements per second.

Radiation Hazard Measuring Instrument
The model 2001 radiation hazard measuring instrument (RAHAM) is constructed in a ruggedized housing and is designed to be utilized by personnel who may be exposed to potentially hazardous levels of nonionizing RF and microwave radiation. It covers the frequency range of 3 MHz to 1 GHz, measures the E-field over the wide dynamic range of 10 to 1000 V/m and features a three-element diode detector that provides an isotropic (omnidirectional) response. The alarm level threshold is set to 200 V/m, but can be factory reprogrammed to meet specific customer needs. The instrument and probe are enclosed within a single rugged housing designed to be rainproof and survive a more-than-three-foot drop onto a solid surface. Operator controls are easily accessible and suitable for gloved users. Size: 9.58" x 2.80" x 1.75". Weight: 1 lb.
General Microwave Corp.,
(516) 226-8900, ext. 236.
Self-contained 65 GHz VNA
The model 37X97 single-unit, self-contained vector network analyzer (VNA) with a frequency coverage to 65 GHz is designed to meet the testing needs of higher frequency systems such as wireless networking, low earth orbit satellite communications systems and intelligent transportation systems. The VNA features electrical performance of > 70 dB dynamic range and > -5 dBm leveled output power. High performance doubler and quadrupler modules with GaAs MMIC output amplifier stages provide the VNA with the capability to make active device measurements over a wide range of input levels. Standard features include a four-channel display for viewing all four S parameters at once. A standard four-sampler architecture offers the highest degree of accuracy and stability. Price: $130,000.
