Keithley Expands RF Measurement Capability to GSM Transmitter Modulation Quality Measurements
Cleveland, Ohio - July 7, 2004 - Keithley Instruments, Inc. (NYSE:KEI), a world leader in advanced electrical test instruments and systems, today added an option for making GSM transmitter quality modulation measurements to its Model 2800 RF Power Analyzer. The Model 2800 with GSM option is a high-throughput, cost-efficient solution that outperforms the high-end spectrum analyzers and communication test sets that are typically used to conduct RF power and transmitter modulation measurements.
Keithley's Model 2800 family provides a flexible, scalable, lower cost, and easier to use solution that increases throughput for manufacturers of mobile phones, RFIC power amplifiers, and related RF devices. With the new GSM option, the Model 2800 measures whether a mobile phone transmitter or RFIC transmitter module conforms to GSM standards for modulated transmissions, capable of both calibrating the phone as well as assessing modulation quality in a single unit. With these new features, the Model 2800 now performs all the transmitter modulation quality tests required by GSM manufacturers:
The Model 2800 RF Power Analyzer product family provides a number of advantages for RF device manufacturers seeking to make RF power measurements:
Major features. Industry standards for wireless phone transmission require measuring power in specified channel bandwidths. The Model 2800 is designed for measuring power in the 800MHz and 900 MHz cellular band, as well as the higher DCS (1700MHz) and PCS (1800MHz) bands and the WCDMA (UMTS) / CDMA2000 bands. The Model 2800 is optimized for testing RFIC wireless phone power amplifiers and wireless phones designed to the AMPS, CDMAOne, North American Digital Cellular (NADC), GSM, GPRS, EDGE, DCS, CDMA2000 1X, CDMA2000 3X, and WCDMA standards.
Market Factors. The mobile phone industry faces challenges in many areas. Design cycles have shrunk to fractions of a year, and production processes must be able to ramp production up/down rapidly. This puts unprecedented demands on production test equipment, which must be flexible enough to test different wireless protocols and frequency bands as designs change. Test equipment must be simple to operate to minimize the time needed to set up production lines. It must increase throughput, which means it must be accurate, repeatable, easy to use, inexpensive for production applications, and small in physical size. And at the same time, it must cost less to buy and to operate. It was with these needs in mind that the Model 2800 was developed.
Unlike bulky and expensive general-purpose spectrum analyzers and communication analyzers, which are extremely versatile instruments intended for the R&D lab, the Model 2800 RF Power Analyzer includes only the capabilities required for wireless production testing, in a package optimized for high-speed production environments. The result is a compact, ready-to-run instrument that is pre-configured with the appropriate frequencies, channel numbers, offsets, and other test parameters specific to the latest wireless standards.
The Model 2800 can be programmed and operated under computer control in automated test systems, eliminating unnecessary features like front panel graphic displays and extensive controls. Advanced digital signal processing (DSP) technology allows the Model 2800 to perform multiple measurements and mathematical operations simultaneously at extremely high speed with minimal user programming.
