IFR Announces Industry's First Multi-Source Signal Generator for Bluetooth
Wichita, Kansas, July 20, 2001 -- IFR Systems, Inc.
(NASDAQ:IFRS) announced today the wireless industryıs first multi-source signal generator capable of generating multiple Bluetooth and GSM carriers within one instrument. For critical Bluetooth interoperability testing, the 2026B with Bluetooth Option
"The 2026 Bluetooth signal source allows developers a less expensive way to test Bluetooth and GSM compatibility," said David Owen, signal sources product manager, IFR. "After all, Bluetooth is designed to be a low-cost technology for consumer devices. Reducing testing costs is critical for Bluetooth designers. Testing is vital to Bluetooth success, but the cost of test should match the low-cost of the technology."
"The Bluetooth option also greatly expands IFRıs customer base. We can offer this low-cost solution to our traditional mobile telephone customers and to new customers designing Bluetooth chipsets, Bluetooth PC plug-in cards, personal digital assistants (PDAs), printers and vending machines," Owen said.
The 2026B, a 10 kHz to 2.51 GHz source, can be fitted with either two or three signal sources that can be combined together onto a common combiner output, or routed to individual outputs. Each of the signal sources can be frequency- and amplitude-coupled so that common measurements, such as intermodulation or receiver selectivity, can be performed more quickly and more accurately than using individual signal generators.
The new option for the 2026B signal source enables the user to perform tests on Bluetooth and GSM receivers and is particularly useful for performing blocking tests. Bluetooth Option 117 can accept external data sources for Bluetooth and GSM generators or it can use internal PRBS (Pseudo Random Binary Sequence) generators. Bluetooth Option 117 has a new RF combiner system that allows an external source of signals (a GSM test set or Bluetooth test set) to be added to the combiner output while using all three of the 2026B sources.
The 2026B multi-source generator saves time and money
The 2026 is the industryıs only multi-source, broadband signal generator. Unlike other signal sources, it can be configured with two or three high-performance, high-power, fully calibrated RF signal sources in a single instrument. Using a 2026B equipped with Bluetooth Option 117 is an economical way to perform Bluetooth and GSM receiver tests without having to spend extra time and money to buy, connect and calibrate two or three signal sources for one test system. The 2026B has a built-in combiner, switches and cables, eliminating uncertainty when connecting separate boxes for two- and three-tone testing. The 2026B with Bluetooth Option 117 also allows the engineer to perform many important tests without having to purchase a costly Bluetooth radio test set.
Multi-source testing for GSM also available
Also available from IFR is the 2026 with Option 116 for GSM to test GSM amplifiers and receivers. Option 116 adds a set of two or three baseband sources that can be connected to each of the external FM inputs of the 2026. By setting the 2026 to external modulation, with the ALC (Automatic Level Control) on, and the deviation set to 67.7 kHz, a GSM carrier can be generated from each of the two or three sources incorporated in the 2026.
All 2026 models offer excellent noise and spurious signal performance Both the 2026 with Option 116 for GSM and the 2026 with Option 117 for Bluetooth/GSM have excellent wide-band noise characteristics. ETSI (European Telecommunications Standards Institute) defines a measurement for wide-band noise where the power measured in a 100 kHz resolution bandwidth on a spectrum analyzer is compared with the carrier power measured in a 30 kHz resolution bandwidth. For an output of +10 dBm on the individual output, a 2026 with Option 116 or 117 typically measures 80 dBc. Application notes describing GSM and Bluetooth testing are available upon request from IFR.
