HP Adapter Speeds Testing of New TDMA Dual-Mode Cellular Phones on the Production Line.PALO ALTO Palo Alto, city, California Palo Alto (păl`ō ăl`tō), city (1990 pop. 55,900), Santa Clara co., W Calif.; inc. 1894. Although primarily residential, Palo Alto has aerospace, electronics, and advanced research industries. , Calif.--(BUSINESS WIRE)--Dec. 4, 1996--Hewlett-Packard Company today introduces an adapter for its HP 8920B radio frequency (RF) communications test set. The new cellular adapter allows manufacturers of analog/digital (dual-mode) mobile phones compatible with Time Division Multiple Access (TDMA (Time Division Multiple Access) A satellite and cellular phone technology that interleaves multiple digital signals onto a single high-speed channel. For cellular, TDMA triples the capacity of the original analog method (FDMA). ) IS-136 standards to completely characterize performance in seconds on the production line. The new cellular adapter, the HP 83206A, complements the full suite of instrument functions and powerful instrument controller contained in the HP 8920B. The result is a complete production-test solution that dramatically reduces the time required to test phones used in Personal Communications Services See PCS. (PCS (1) (Personal Communications Services) Refers to wireless services that emerged after the U.S. government auctioned commercial licenses in 1994 and 1995. This radio spectrum in the 1. ) operating at 800 megahertz One million cycles per second. See MHz. MegaHertz - (MHz) Millions of cycles per second. The unit of frequency used to measure the clock rate of modern digital logic, including microprocessors. (MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. ) and 1900MHz in the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area. . In only a few seconds, the HP 83206A and HP 8920B can evaluate a phone's performance and determine if it conforms to established standards. The new adapter tests the cellular phone's ability to set up a call with a Digital Control Channel (DCCH DCCH Dedicated Control Channel (GSM) DCCH Digital Control Channel (TDMA cellular systems) ). With or without a call setup, parametric tests on the receiver and transmitter as well as call-processing functions can be easily controlled from the front panel or through software. The software package -- the HP 11807E Option 014 -- contains more than 60 tests, including RF power, receiver sensitivity, mobile assisted hand-off (MAHO MAHO Mobile Assisted Hand Off (TDMA) MAHO Mobile Assisted Hand over ) and call-processing registration. In addition, the power-measurement demands of the TDMA access method can be satisfied by adding Option 006, which provides average-power measurements with accuracy of +/-5 percent at power levels as low as 50 micro W. The adapter simplifies even the most complex DCCH measurements, from programming a test sequence to production-line trouble-shooting. It features intuitive call processing, an on-call parametric-test interface and employs high-level HP-IB HP-IB - IEEE 488 (HP Interface Bus) commands that simplify programming of call-processing functions by the user. U.S. PRICING AND AVAILABILITY The HP 8920B with the HP 83206A TDMA cellular adapter is available now for $31,700. The HP 83206A TDMA adapter is available separately for $12,700. The HP 11807E Option 014 is available for $2,040.
