“Design
waveform files from simple generic or system specific templates”
® is an easy to use WindowsTM application for generating digital communications standard waveforms for use with Cobham digital signal generators and arbitrary waveform generators. enables a user to design waveform files from simple generic or system specific templates as well as convert a user’s own waveform into compatible formats.
Waveforms designed in can include signal impairments and time markers to aid synchronisation. Graphical displays of the waveform’s FFT, vector and constellation diagrams, etc. can be viewed and exported for use in other Windows™ applications.
Where supported waveforms can be downloaded directly into the instrument from .
In addition to storing generated waveforms, a user may save configurations that may later be recalled and easily modified.

Modulation formats is suitable for the generation of single carrier generic or framed signals as well as multi-carrier and multi-tone signals. It also allows users to package and download their own I/Q data files generated in third party software tools such as MATLAB®.
• Generic PSK, FSK, QAM or framed CDMA, TDMA, WLAN, WPAN, WMAN modulation types • Tones or multicarrier • Nyquist, Root Nyquist, Low Pass, Gaussian and user defined filters • PRBS, fixed pattern and user-defined data sources • 4 markers with automatic burst control • RF burst or IQ level profiling
• IQ errors and AWGN • Spectrum, CCDF, vector, constellation, code domain power • IQ vs. time • Amplitude vs. time • Phase vs. time • Frequency vs. time • Download and file management utility • On-line help
