User manual TEKTRONIX AWG7000

[. . . ] Together the AWG7000 and RFXpress provide engineers with “bandwidth on demand”, which is the ability to generate wideband modulated signals up to 5. 3 GHz (–3 dB) anywhere within the 9. 6 GHz frequency range. The latest digital RF technologies often exceed the capabilities of other test instruments because of the need to generate the wide-bandwidth and Radar Signal Creation Generating advanced radar signals often demands exceptional performance from an AWG in terms of sample rate, analog bandwidth, and memory. The Tektronix AWG7000 Series sets a new industry standard for advanced radar signal generation, by delivering wide modulation bandwidths up to 5. 3 GHz (–3 dB). With a sample rate of up to 24 GS/s the AWG7000 Series can directly generate RF signals never before possible from an AWG. [. . . ] The AWG7000 Series, when coupled with RFXpress, allows users to configure every part of the OFDM signal definition. Engineers can build signals symbol-by-symbol to create a complete OFDM frame or let the RFXpress software choose default values for some signal aspects. The AWG/RFXpress combo supports a variety of data coding formats that include Reed Solomon, Convolution, and Scrambling. Users also have the ability to define each subcarrier in the symbol which can be configured independently for type, modulation, and base data. The RFXpress software gives visibility into all aspects of the OFDM signal by providing a symbol table that gives a summary of all the carriers in the selected symbol. OFDM packets/frames can be built by specifying the spacing between the symbols/frames and parts of the OFDM packets can be stressed by adding gated noise. Direct WiMedia signals are easily created with the AWG7000 and RFXpress. UWB-WiMedia (UWBCF/UWBCT) Ultra-Wideband (UWB) wireless is a growing technology that is designed for low-power, short-range wireless applications. UWB has emerged as the leading technology for applications like wireless Universal Serial Bus (USB). UWB radios, like generic OFDM radios, require wide signal bandwidths and multiple carriers, but UWB designs also require short-duration pulses and transmit Power Spectral Densities (PSDs) near the thermal noise floor which can make creating UWB test signals very difficult. Fortunately, the AWG7000 Series and RFXpress offer a solid solution for the generation of UWB test signals. The AWG7000 and RFXpress have the capability to digitally synthesize and generate signals in the UWB spectrum. For either custom UWB signal or ones defined for the latest WiMedia specification, the AWG7000 solution can recreate signals that are required to band hop in real time over a 1. 6 GHz modulation bandwidth.
