RF Signal Generation Made Easy
RF signals are becoming more and more complex, making it more difficult for RF engineers to accurately create the signals required for conformance and margin testing. To address this design challenge, RFXpress delivers advanced RF/IF/IQ creation and editing tools. RFXpress is a software package that digitally synthesizes modulated baseband, IF, and RF signals taking signal generation to the new levels by fully exploiting the wideband signal generation capabilities of Tektronix arbitrary waveform generators (AWGs).
Digitally Modulated signals are easily created with the base RFXpress package. Supporting a wide range of modulation schemes, the software allows users to create standard waveforms or customized waveforms with specific modulation and frequency-hopping criteria. In Auto mode, the software can automatically calculate the waveform length (in time (sec), samples, or symbols) and the sampling rate required to accurately create the desired output from the arbitrary waveform generator.
RFXpress also includes a calibration feature that can pre-distort the signals to provide flat frequency and linear phase response from the AWG output. RFXpress enables users to easily replicate waveforms from Tektronix oscilloscopes (*.wfm), and IQ waveforms of a real-time spectrum analyzer (*.iqt, *.tiq). Impairments, distortion, or interference can then be added to thoroughly stress test designs.
Radar Signal Creation is a software module for RFXpress that provides the ultimate in flexibility for creating Pulsed Radar waveforms. It gives users the ability to build custom Radar Pulse suites starting from pulse-to-pulse trains to pulse groups. It supports a variety of modulation schemes including LFM, Up-Down Chirp, QPSK, BPSK, Barker/Frank/Polyphase Codes including P1/P2/P3/P4, Step FM, Nonlinear FM, User-defined Step FM/AM and Step PM/AM, and Custom Modulation. It also has the ability to generate pulse trains with staggered PRI to resolve Range and Doppler ambiguity, frequency hopping for Electronic Counter-Counter Measures (ECCM), and pulse-to-pulse amplitude variation to simulate Swerling target models, including antenna scan patterns, clutter, and multipath effects.
Environment Signal Creation is a software module that allows you to emulate the interference between Radar and other communication standards to test Radar receivers under realistic and worst-case conditions. The users can configure the various standard-specific parameters of these interfering signals including power levels, start time, and duration. The time and frequency overview enables them to adjust the above parameters to quickly create worst-case scenarios. The standards that are supported in the environment module include WiMAX, WiFi, GSM, GSM-EDGE, EGPRS 2A, EGPRS2B, CDMA, W-CDMA, DVB-T, and CW Radar. It also allows seamless integration of signals created using other RFXpress plug-ins such as Generic, Radar, OFDM, and WiMedia.
Generic OFDM Creation is a software module for RFXpress that allows users to configure every part of the OFDM signal definition. It allows users to build the signal symbol-by-symbol to create a complete OFDM frame. RFXpress supports a variety of data coding formats that include Reed Solomon, Convolution, and Scrambling. Each subcarrier in the symbol can be configured independently for Type, Modulation, and Base Data. You could then add Zero Padding or Cyclic Prefix. Symbols can be modified by specifying the clipping ratio and tone nulling. A symbol table gives you a summary of all the carriers in the selected symbol. OFDM packets/frames can be built by specifying the spacing between the symbols/frames. Parts of the OFDM packets can be stressed by adding Gated Noise to it.
SPARA is a software module for RFXpress that provides emulation of RF components from touchstone files. You can cascade multiple touchstone files to emulate a RF chain. The effect of the RF component can also be de-embedded by selecting the Inversion option. This option also adds a provision to characterize a two-port device (DUT). A wizard guides you through a step-by-step process to obtain S21 characteristics (Insertion Loss) of the device in a text format.
UWB-WiMedia (UWBCF/UWBCT) is a software module for RFXpress that has the capability to digitally synthesize and generate signals in the UWB spectrum. As per the latest WiMedia specification, the software module can recreate signals that are required to band hop in real time over 1.5 GHz modulation bandwidth. UWBCF/UWBCT gives users complete control over the characteristics of the WiMedia signal including the preamble synchronization sequences, cover sequences, and TFCs in all band groups. All six band groups (BG1 to BG6) can be generated in either IQ, IF, or Direct RF signals giving users 3 different options for creating/up-converting the signals. The software operates in two modes, in the conformance mode (UWBCF) users can generate the standard waveforms that conform to the latest version of the WiMedia’s specifications, in the custom mode (UWBCT) users can adjust any part of the signal header or payload to perform for stress and margin testing.
RFXpress runs on a PC or as an integral part of Tektronix AWG7000 and AWG5000 Series arbitrary waveform generators.
