Sound card based real time oscilloscope, spectrum analyzer and signal generator

Multi-Instrument is a powerful sound card based multi-function virtual instrument software. It supports sophisticated triggering technique including pre-trigger and post-trigger, level trigger and differential trigger. It Supports 8, 16, 24 bits.

These are the main features of this software

• LCR meter
• Data Logger
• Spectrum 3D Plot: including waterfall and spectrogram.
• Multimeter: voltmeter, sound pressure level meter(dB, dBA, dBB, dBC), frequency counter, RPM meter, counter, duty cycle meter, F/V converter. The counter trigger level and hysteresis is adjusted.
• Signal Generator: Function generation, multitone generation, arbitrary waveform generation, burst tone generation, MLS generation, DTMF generation, musical scale generation, white noise and pink noise generation, and frequency/amplitude sweep. Synchronized operation between the signal generator and the oscilloscope is supported.
• Spectrum Analyzer: RMS amplitude spectrum, relative amplitude spectrum, octave analysis (1/1,1/3,1/6,1/12,1/24), frequency compensation, frequency weighting (A,B,C,ITU-R 468), peak hold, averaging, measurement of THD, THD+N, SNR, SINAD, Noise Level, IMD, Bandwidth and Crosstalk, phase spectrum, auto correlation function, cross correlation function, coherence function, transfer function, impulse response. Support 55 window functions and window overlap.
• Oscilloscope: Dual-trace waveform, Waveform addition and subtraction, Lissajous Pattern, transient/long-time signal recording, voltmeter. Various digital filters are supported.

· Device Test Plan: Device Test Plan provides a mechanism for you to configure and conduct your own device test steps. It takes the advantage of the sound card's capability of simultaneous input & output, to generate a stimulus to the Device Under Test (DUT) and acquire the response from that device at the same time. Different stimuli is generated and the response is analyzed in different ways.

Requirements for this software

· 8, 16 or 24 bit Windows compatible sound card

Limitations of this software

· 21 days trial
