The '''Tektronix 2641''' is a Fourier analyzer that links dedicated signal acquisition and analysis with a personal computer’s mass storage and graphics. | |||
It allows measurement solutions for electrical, mechanical, and electromechanical applications in the DC to 100 kHz frequency range. | |||
Typical applications are Structural Analysis, Control Systems, Machine Vibration, Audio and Acoustic Tests, and General Purpose Signal and System Analysis. | |||
Each of the channel inputs provide simultaneous sampling of all channels utilizing 12 bit ADC standard or 16 bit ADC optionally. | |||
Signal processing includes Fourier Transform ([[wikipedia:Fast_Fourier_transform|FFT]]) and Spectral Lines. | |||
The signal generator has a wide variety of functions, like sine, square, sawtooth, triangle, input, random, adjustable random, chirp, and arbitrary. With the optional TurboPac Application Library and Run-Time License advanced measurement calculations and graphs can be generated from the data collected. | |||
The PC’s monitor displays the measurements results – but that’s where the Fourier Analyzer dependence on the PC stops. | |||
All of the data acquisition, data management, signal processing and other computationally intensive operations | |||
are reserved for the Fourier Analyzer’s high-performance measurement and analysis hardware. | |||
Built-in analog and digital anti-alias filters automatically track all of the bandwidth settings. | |||
A selection of frame sizes allows the user to choose the best trade-off between acquisition time and frequency resolution. | |||
When high frequency resolution around a specific signal is needed, the option "zoom" feature can be used. | |||
It allows one to focus up to 1600 spectral line with a span as small as 10 Hz about the frequency of interest. | |||
