Anritsu Co. Measurement Solution for Handset Power Amplifiers
Anritsu Co. Corp. introduced the ME7840/4 handset power amplifier test system (PATS), a single connection solution that characterizes the performance of next-generation handset power amplifiers. By integrating the measurement capabilities of five instruments with a high power test set, PATS streamlines handset power amplifier test, resulting in lower capital equipment expenditures, enhanced productivity, and improved time-to-market, the company says.
The handset PATS consists of Anritsu's Scorpion Vector network measurement system (VNMS), and Scorpion Navigator software. With the integration of the Scorpion VNMS, Handset PATS includes a suite of measurements, including the capability to tune for swept power gain compression and intermodulation distortion (IMD). Other single connection tests include S-parameters, harmonics, and noise figure from 50 MHz to 6 GHz. For adjacent channel power ratio (ACPR) measurements, the test set also includes an auxiliary path for connection to an external signal generator and analyzer.
The Scorpion Navigator software improves the time-consuming and often tedious setup, calibration, measurement, and reporting activities typically associated with power amplifier tests, the company says. With Windows compatibility, Scorpion Navigator is easily installed on most computers, providing immediate access to a suite of single-tone, two-tone, and modulated measurement tools, the company says.
For further flexibility, the Scorpion Navigator contains an automated feature that enables the orchestration of further custom measurement scenarios. For example, the Scorpion Navigator can handle external pulse generators and power supplies to characterize power amplifiers under pulse or various bias conditions.
The handset PATS is priced at $99,225, and is available in four to six weeks ARO.

Bluetooth Analyzer With v1.2 Capabilities
Computer Access Technology Corp. (CATC) recently demonstrated its BTTracer/Trainer, a Bluetooth protocol analysis system that supports the proposed Bluetooth v1.2 protocol standard. The CATC analysis system helps developers test and verify their Bluetooth products by capturing, decoding and displaying v1.2 traffic for protocol analysis and system debug.
During the demonstration, the BTTracer/Trainer successfully captured adaptive frequency hopping (AFH), fast connect and eSCO traffic, each of which are new functions defined in the Bluetooth v1.2 specification.
The BTTracer/Trainer is the fifth member of CATC's line of Bluetooth development tools and verification systems. It combines a Bluetooth protocol analyzer and a Bluetooth exerciser into a single system that shortens development processes and accelerates time to market, the company says.
CATC will begin shipments of the BTTracer/Trainer with Bluetooth v1.2 support in June 2003. Existing BTTracer/Trainer customers will be able to upgrade their systems to support the new v1.2 specification.

7 GHz Differential SMA Probe Head
Agilent Technologies Inc. introduced what the company is calling the industry's first 7 GHz differential SMA probe head. The new Agilent InfiniiMax active probe head features three new serial bus validation and compliance testing capabilities for the Agilent Infiniium oscilloscope.
The Agilent E2695A Differential SMA probe head is an accessory that plugs into the Agilent InfiniiMax 1130 series of probe amplifiers. The product provides differential SMA connections using a single scope channel. Using the differential SMA probe head, the Agilent 54850 Infiniium oscilloscope series can now measure and display four differential signals simultaneously.
The E2695A Differential SMA probe head is expected to be available in July for $995.

IS-136 System FDCCH Decoding Receiver
Dynamic Telecommunications Inc., a PCTEL Inc. company, announced the release of its forward dedicated control channel (FDCCH) decoding receiver for IS-136 wireless networks.
The FDCCH decoding receiver for IS-136 systems decodes system identity (SID) and dedicated control channel (DCCH) structure messages from the FDCCH, demodulating IS-136 layer 3 messages and digital verification color code (DVCC) messages on control and traffic channels.
The IS-136 FDCCH decoding receiver does not use a cellular handset to monitor control channels, avoiding the limitation of monitoring only one channel per handset. The IS-136 handset-free decoding receiver also eliminates the requirement for network registration, a long-standing burden for government-related applications.
