Stanford SR1 200kHz Dual-domain Audio Analyser

For the most demanding analog and digital audio applications

Stanford Research Systems

The SR1 Dual-Domain Audio Analyser from Stanford Research Systems is a stand-alone instrument that delivers cutting edge performance in a wide variety of audio measurements. With a versatile high-performance generator, an array of analysers that operate symmetrically in both the analog and digital domains (and digital audio carrier measurements at sampling rates up to 192kHz) the SR1 is the right choice for the most demanding analog and digital audio applications.


  • Analog/digital domain measurements
  • ? -112dB THD+N
  • 200kHz frequency range
  • ? -118dBu analog analyser noise
  • ± 0.008dB flatness
  • Low crosstalk
  • ? 600ps jitter 50Hz to 100kHz
  • Dual-channel FFT's

User Interface
SR1 uses an integrated computer running the Windows XP embedded operating system, so operation will be immediately familiar and intuitive. Depending on the application, the SR1 can be operated with an external mouse and keyboard, or by using the front-panel knob, keypad and touchpad.

Seven on-screen tabbed pages are available for arranging panels, graphs and displays. Screen setups, data and instrument configurations can be quickly saved and recalled to either the internal hard disc or to a flash drive connected to one of the two front-panel USB connectors. An optional 1024 x 768 XVGA monitor (opt 02) provides better resolution and allows more information to be displayed.

Analog Signal Generator
At the heart of the SR1 is a uniquely flexible analog signal generator. All of the standard audio waveforms are available including sine, synchronous burst sine, noise (white, pink and filtered), standard intermodulation test signals (SMPTE, CCIF, DIM), square waves, arbitrary waveforms (ASCII and .WAV), ramps and multitone waveforms. Many of these signals can be combined in the generator allowing you to create an unlimited number of test waveforms.

But the analog signal generator doesn't sacrifice performance for flexibility. With a flatness of +/-0.008dB (20Hz to 20kHz) and a residual THD+N of -108dB (20Hz to 20kHz) SR1's Low Distortion Sine rivals the performance of any analyser.
