IFR Adds Remote Operation, Trunked Radio Testing and New Test Patterns to 2975 Radio Test Set.Business Editors/High-Tech Writers WICHITA, Kan.--(BUSINESS WIRE)--Dec. 18, 2002 IFR IFR abbr. instrument flight rules , an Aeroflex company (Nasdaq:ARXX), today announced it has added important new test capabilities to the 2975 radio test set. Through new firmware upgrades, the 2975 radio test set now includes many new test patterns, the ability to remotely control 2975 tests via the Internet, and the ability to test P25 trunked radios in the 800 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. band. "IFR continues to enhance the 2975 with new features to make life easier for those who use and test Project 25 radios, while expanding applications for the P25 market. As a modular test platform, the 2975 will gain additional new functions in the upcoming months," said Rob Barden, senior product marketing manager, IFR. Remote Testing Capability Allows Users to Monitor Hard-to-Reach Locations With the free firmware upgrade (version 1.5.0), the 2975 radio test set can be operated remotely through the Internet. Using the instrument's exclusive Ethernet connection, the 2975 can be assigned a specific Internet Protocol See Internet and TCP/IP. (networking) Internet Protocol - (IP) The network layer for the TCP/IP protocol suite widely used on Ethernet networks, defined in STD 5, RFC 791. IP is a connectionless, best-effort packet switching protocol. (IP) address, creating a "virtual" instrument that can be redirected to a remote user for monitoring and testing purposes. This greatly enhances the ability to track down intermittent or gradual degradation of sites that are remote and hard to access for on-site testing. Now the operator can remotely monitor repeater/transmitter locations from the virtual instrument. From thousands of miles away, the user can have the 2975 monitor remote, hard-to-reach locations from a central command center and test for system performance over time. System degradation and intermittent problems occurring randomly or over extended periods of time can be monitored and found without spending costly personnel time and effort trying to conduct tests in remote transmitter locations. New Test Patterns and "Quick Tune" Spectrum Analyzer A hardware device or software used to examine the frequency and power components of a signal. It provides more information than an oscilloscope, because it can display the signals over a range of frequencies. Allow Greater Ability to Verify Performance The free firmware upgrade also includes a whole new set of standard test patterns. IFR has implemented 14 patterns to verify performance in accordance with TIA-EIA-102 CAAA CAAA Clean Air Act Amendments of 1990 CAAA California Applicants' Attorneys Association CAAA Crane Army Ammunition Activity CAAA California Agricultural Aircraft Association CAAA Clean Air Act Authority CAAA Commuter Airline Association of America Digital C4FM/CQPSK Transceiver Measurement Methods. These patterns allow engineers to quickly access technically correct patterns to assist in the design and test of P25 transceivers. The 2975 also includes a new feature designed for fast location of harmonics using the instrument's built-in spectrum analyzer. With the 2975's exclusive PS2-compatible mouse, the operator can double click on a signal and the 2975 will automatically tune the center frequency to the selected signal. Exclusive Trunking Option Added to Support P25 Trunking Operation in the 800 MHz Bandwidth Also announced today is an additional new firmware release for the 2975, Option 4, that supports P25 trunking operation in the 800 MHz band. Option 4 enables the 2975 with a repeater (1) A communications device that amplifies (analog) or regenerates (digital) the data signal in order to extend the transmission distance. Available for both electronic and optical signals, repeaters are used extensively in long distance transmission. simulator to test P25 trunked radios. This feature is not available on any other P25 test set today. Option 4 will emulate a repeater, with "Push to Talk" features that allow the operator to talk directly to the radio under test without going through a predetermined pre·de·ter·mine v. pre·de·ter·mined, pre·de·ter·min·ing, pre·de·ter·mines v.tr. 1. To determine, decide, or establish in advance: test sequence. The 2975 quickly tests the transmitter performance of the radio in less than 20 seconds with quick visual indicators of power, frequency error and C4FM C4FM Constant Envelope 4-Level Frequency Modulation Error Vector Magnitude The error vector magnitude or EVM is a measure used to quantify the performance of a digital radio transmitter or receiver. A signal sent by an ideal transmitter or received by a receiver would have all constellation points precisely at the ideal locations, however various . The trunking option also includes the ability to test protocol functionality for interoperability testing. The user can set and decode control channel parameters and radio communication messages for P25 trunked radio communications. About the 2975 Radio Test Set The 2975 is a digital radio test platform that tests radio equipment to ensure compliance under the Project 25 standards, including: -- Parametric testing for compatible four-level frequency modulation (C4FM) -- Interoperability testing for Common Air Interface -- Improved multi-band excitation (IMBE) vocoder for voice testing -- Project 25 compliant Type III encryption testing Providing independent "generate and receive" functions from 1 MHz to 2.7 GHz, the 2975 allows duplex operation over a full instrument range. This enables a wide variety of system configurations to be tested including cross-band repeaters. Additionally it has two audio-function generators to support conventional FM terminal testing. Created with a modular design In the context of systems engineering, modular design — or "modularity in design" — is an approach aiming to subdivide a system into smaller parts (modules) that can be independently created and then used in different systems to drive multiple functionalities. , the 2975 is simple to support and upgrade. Its internal hard drive and 3.5-inch floppy drive See floppy disk. floppy drive - disk drive simplify program installation and maximize flexibility in storage and recall of setup information and test data. Software upgrades can be downloaded, allowing features to be added as new radio-specific tests are developed, reducing ownership and life-cycle costs. Price and Availability The 2975 radio test set has a base price of U.S. $19,995 with full P25 conventional and analog operation. The base price includes version 1.5.0 firmware for remote monitoring (protocol) remote monitoring - (RMON) A network management protocol that allows network information to be gathered at a single computer. Whereas SNMP gathers network data from a single type of Management Information Base (MIB), RMON 1 defines nine additional MIBs that provide a , new patterns and the exclusive "Quick Tune" spectrum analyzer feature. For existing 2975 owners, these new features are free firmware upgrades that can be completed in the field for 2975 radio test sets that have been through the version 1.3.0 upgrade procedure. Option 4, the P25 trunking firmware, is priced at U.S. $1,900. Delivery for the 2975 is six weeks upon receipt of order. Firmware upgrade 1.5.0 is available immediately and can be downloaded from IFR's website at www.ifrsys.com.
