xWave

xWave generates the signals needed for audio amplifier and speaker testing. The interface is intuitive and provides all of the necessary controls without excessive screen clutter.

Features

• All of the standard waveforms are present - sine, square, triangle, and sawtooth. Frequency range is 1 HZ - 22050 Hz.
• The square wave has a choice of 20 us or 40 us rise time. The slow setting reduces the ringing inherent in a digital filter, while the fast setting provides the maximum harmonic content.
• The Sweep function provides a continuous frequency sweep containing signals in a selected audio range.
• The Burst function outputs from 1 to 20 waves in a repeated sequence.
• The left channel can be switched to a sync signal, necessary for triggering on sweep and burst modes.
• The right channel phase can be adjusted from 0 - 180 degrees with respect to the left channel or sync.
• An important feaure is the Calibration mode, which allows the user to adjust the displayed output voltage to the actual measured output.
• All settings are saved between runs.
• xWave has been designed to be versatile yet easy to use.

• The Spectrum function is an exciting addition to the xWave waveform suite. More flexible than the usual noise generator, it enables generation of random noise restricted a user-defined frequency band. For instance, if you want noise only between 1000 Hz and 2000 Hz, xWave can do it ! In addition, there have been a few tweaks to the user interface, including a selectable darker background.
