SR1 Audio Analyser

Stanford Research launch the SR1 Audio Analyser

The SR1 Dual-Domain Audio Analyzer is a stand-alone instrument that delivers cutting edge performance in a wide variety of audio measurements.

SR1 uses an integrated computer running the Windows XP embedded operating system, so operation will be immediately familiar and intuitive.

Depending on the application, SR1 can be operated with an external mouse and keyboard, or by using the front-panel knob, keypad and touchpad.

At the heart of 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.

SR1 Eye diagram
  • ≤ -108 dB THD+N (analog system at 1 kHz, 20 kHz BW)
  • 200 kHz (signal generation & measurements including FFTs)
  • ≤ -114 dBu analog analyzer noise ( 20 kHz BW)
  • ± 0.008 dB flatness (analog system, 20 Hz to 20 kHz)
  • Low Crosstalk (≤ -140 dB analog inputs)
  • ≤ 800 ps jitter (700 Hz to 100 kHz)
  • Dual-Channel FFTs

The same flexibility and performance is found in SR1ís digital audio signal generator. Almost all the same waveforms found in the analog generator are available in the digital generator with the addition of several special digital test waveforms including digital constant, walking bits, and a staircase waveform (for D/A testing).

SR1 provides a complete set of measurements for digital interface testing. Carrier level and sampling frequency are measured directly. Status bits are fully decoded in both professional and consumer formats, and user bits are displayed as well.

SR1ís Jitter Analyzer measures jitter in both the time and frequency domain, including continuously variable bandwidth limiting and weighting in both domains. For frequency domain measurements, live zoomable and heterodyned spectral displays of jitter are available. With a residual jitter of only 800 ps, the performance of SR1ís jitter analyzer is unbeatable.
