RENT Stanford Research SR1 (call for availability)
The SR1 Audio Analyzer epitomizes innovation in the realm of audio testing and analysis. Designed for versatility and precision, this state-of-the-art instrument is equipped with a high-performance signal generator, capable of producing a myriad of audio measurements. With operational capabilities spanning both analog and digital domains and digital audio carrier measurements at sampling rates up to 192 kHz, the SR1 ensures unmatched fidelity in your audio assessments.
Powered by an integrated computer that runs on the Windows XP embedded operating system, the SR1 features highly configurable panels that empower users with the flexibility to tailor their analyzer settings to meet specific requirements.
Among its cutting-edge capabilities, the SR1 offers a unique analog signal generator that allows for the creation of an unlimited variety of test waveforms. This includes
Multitone waveforms with up to 50 tones, each capable of real-time adjustments in frequency, amplitude, and phase. The innovative
FFT Chirp waveform is automatically synchronized to the FFT analyzer, enabling instant frequency response measurements (both magnitude and phase).
The SR1 also provides a comprehensive digital audio signal generator, incorporating nearly the same waveforms found in its analog counterpart, along with an assortment of additional digital test waveforms. This ensures that users have access to a wide range of testing options suitable for both analog and digital signals.
Precision timing is a hallmark of the SR1, with all sampling clocks derived from an internal timebase boasting an accuracy of 2 ppm. For the most stringent applications, an optional atomic rubidium (FS725) timebase offers extraordinary accuracy with a shipped specification of
+5 x 10
-11 and a 20-year aging specification of less than 5 ppb. This timebase can also synchronize with external clocks, AES11 reference signals, or standard video signals.
The SR1 incorporates a versatile set of analyzers that operate symmetrically on both analog and digital audio signals without necessitating additional options. The system supports simultaneous operation of up to two analyzers across either analog or digital inputs.
Featuring a
Time Domain Detector, the SR1 performs all essential audio measurements including Amplitude, Crosstalk, and THD+N. Additionally, it includes continuously variable bandwidth limiting and standard weighting filters. The post notch-filter distortion signal can be routed to an FFT analyzer for a live spectral display of distortion, or sent to the rear-panel monitor output or speaker, making it an invaluable tool for digital interface testing.
The SR1 shines in terms of user interaction and automation capabilities. Users can write on-board scripts in VBScript, Jscript, or Python, enjoying full access to all instrument features while also enabling the creation of straightforward user interfaces for test operations. The instrument boasts a comprehensive hierarchical GPIB command set, allowing GPIB commands to be communicated through the standard IEE-488 interface, RS-232 port, or an Ethernet TCP/IP network (VXI-11). Furthermore, a complete COM interface provides the option for instrument operation automation from any COM-capable application, including Visual Basic, LabView, or Microsoft Office.
