First Test Instruments Supporting EDR Transmitter Test Cases Available Now From Anritsu Company; Software Allows MT8850A and MT8852A Test Sets to Perform All Three EDR Transmitter Measurements Defined in New Bluetooth Standard.RICHARDSON, Texas Richardson is a suburb in Dallas County and Collin County, Texas. As of the 2000 census, the city had a total population of 91,803, while according to a 2006 estimate, the population had grown to 99,200. -- Anritsu Company introduces Enhanced Data Rate (EDR (Enhanced Data Rate) An acronym occasionally used to reflect an advancement in transmission or transfer speed. For example, Bluetooth 2.0 + EDR provides a dramatic increase in speed over the previous version. See Bluetooth. ) transmitter test software for its MT8850A and MT8852A Bluetooth(R) test sets. With the software, which is available immediately, the MT8850A and MT8852A are the first test instruments that support all EDR transmitter test cases. This capability allows Bluetooth developers to test the transmitter performance of their EDR chipsets and products against industry standards quickly, significantly reducing development time. The release of the software provides engineers with an affordable test solution to verify the performance of their devices before submitting them for qualification. After customers install the software in the MT8850A or MT8852A, the test sets can perform all three EDR transmitter measurements defined in the new Bluetooth standard. With the software, the test sets can measure differential power, carrier frequency stability, and modulation accuracy (DEVM), as well as detect transmitter encoding errors. The EDR relative transmit power measurement displays the differential power for GFSK GFSK Gaussian Frequency Shift Keying to PSK (1) See preshared keys. (2) (Phase Shift Keying) A simple digital modulation technique that uses two different phase angles for 0 and 1. Quadrature PSK (QPSK) uses four phase shifts for each two bits of input. See phase modulation and DPSK. modulation with +/-0.2 dB accuracy for differential power of less than 6 dB. Carrier frequency stability error and block frequency error accuracy is +/-1 kHz, while DEVM accuracy is less than 5% RMS for both pi/4DQPSK DQPSK Differential Quadrature Phase Shift Keying DQPSK Differential Quaternary Phase Shift Keying and 8DPSK (Differential Phase Shift Keying) A common form of phase modulation used in analog modems. DPSK does not require complex demodulation circuitry and is less susceptible to random phase changes in the transmitted waveform. See PSK, FSK and QPSK. modulation. The differential phase encoding See PE. displays the packet error analysis with the number of failed symbols. All major packets - including 2-DH1, 2-DH3, 2-DH5, 3-DH1, 3-DH3, and 3-DH5 - are supported by the software. The MT8850A and MT8852A demodulate To isolate a data signal from a carrier wave. The demodulation circuit uses the unmodulated carrier as a reference signal and compares it to the received signal. See modulation and carrier. demodulate - demodulation packets transmitted from EDR Bluetooth devices under test without the need to establish a test mode connection. This makes the application ideal for developers of Bluetooth EDR chips, allowing radio layer measurements to be performed before the completion of test mode signaling development within the chip's protocol stack The set of protocols used in a communications network. A protocol stack is a prescribed hierarchy of software layers, starting from the application layer at the top (the source of the data being sent) to the data link layer at the bottom (transmitting the bits on the wire). . The MT8850A has been specifically designed for rapid testing of Bluetooth wireless links. The MT8852A offers all of the radio layer measurement capability of the MT8850A and adds support for audio measurements. The EDR transmitter test software is priced at $5000, and is available now for immediate delivery. Pricing of the MT8850A and MT8852A are $16,840 and $22,105, respectively.
