Stanford SR770 FFT Analyser

Ideal for acoustics, vibration, noise measurement and general electronic use

Stanford Research Systems

 

The SR770 is a single-channel 100kHz FFT spectrum analysers from Stanford Research Systems with a dynamic range of 90dB and a real-time bandwidth of 100kHz. Additionally, it includes a low-distortion source which allows you to measure the transfer functions of electronic and mechanical systems. The speed and dynamic range of these instruments, coupled with their flexibility and many analysis modes, makes them the ideal choice for a variety of applications including acoustics, vibration, noise measurement and general electronic use.

 

Features:

  • DC to 100kHz bandwidth
  • 90dB dynamic range
  • Low-distortion synthesised source (SR770)
  • Harmonic, band and sideband analysis
  • 100kHz real-time bandwidth
  • Hardcopy output to printers and plotters
  • GPIB and RS-232 interface

High Dynamic Range
The SR760 and SR770 have a dynamic range of 90dB. This means that for a full-scale input signal, the instruments have no spurious responses larger than -90dBc (1 part in 30,000). Even signals as small as -114dBc (1 part in 500,000) may be observed by using averaging. The low front-end noise and low harmonic distortion of the SR760 and SR770 allow you to see signals that would be buried in the noise of other analysers.

 

Powerful Processing
The SR760 and SR770 use a pair of high-speed, 24-bit digital signal processors (DSP's) to filter heterodyne and transform sampled data from its 16-bit analog-to-digital converter. This computing capability allows the analysers to operate at a real-time bandwidth of 100kHz. In other words, the SR760 and SR770 process the input signal with no dead time. Your measurements will be done in as little as a tenth of the time of other analysers, which typically have a real-time bandwidth of about 10kHz.

 

Easy to Interface
All functions of the analysers can be queried and set via the standard RS232 and GPIB interfaces. A comprehensive set of commands allows complete control of your analyser from a computer. Data can be quickly transferred in binary format, or more conveniently is ASCII format. The complete command list is available as a help screen in the instruments for convenient reference while programming.
