Multi-Instrument is a powerful multi-function test and measurement virtual instrument software. It is a professional tool for time, frequency and time-frequency domain analysis. It supports a variety of hardware ranging from sound cards which are available in almost all computers to proprietary ADC and DAC hardware such as VT DSOs, NI DAQmx cards and so on.
It consists of the following instruments and functions. [Oscilloscope]: Dual-trace waveform, Waveform addition, subtraction & multiplication, Lissajous Pattern, signal recording. Various digital filters are supported. [Spectrum Analyzer]: Amplitude spectrum, octave analysis (1/1,1/3,1/6,1/12,1/24, 1/48, 1/96), 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. [Signal Generator]: sine, rectangle, triangle, saw-tooth, white and pink noise, DMTF, MLS, Multi-Tones, frequency sweep, amplitude sweep, burst tone. Other instruments including [Multimeter], [Spectrum Waterfall Plot], [Spectrogram], [Data Logger], [LCR Meter], [Device Test Plan] and [Vibrometer].
