Audio Precision ATS-2, Начало работы

Страница: 12 / 76

The PC communicates with the ATS-2 chassis via a proprietary bus
interconnection called the Audio Precision Interface Bus (APIB), which
requires a dedicated cable and a PC-mounted interface card or adapter.
APIB interfaces can be ordered as PCI and PCMCIA compatible devices.
See Chapter 2 for further information on APIB and interface hardware.
When ordered in the optional GPIB configuration (ATS2G), ATS-2 can
also be controlled by the industry-standard IEEE 488.2 General Purpose
Interface Bus (GPIB). See Chapter 7 for more information about the
ATS-2 GPIB configuration.
ATS-2 Capabilities
§
ATS-2 can make amplitude, frequency, THD+N, noise, phase,
crosstalk, bandpass, and IMD measurements for analog or digital
audio devices. In a special function, ATS-2 can perform detailed
analysis and measurement of harmonic distortion products.
§
ATS-2 can perform complex sweeps, and display and print the results
with a powerful graphing engine. ATS-2 offers control over
instrument regulation and settling parameters. Data obtained from
sweeps can be compared to pre-defined limits. A variety of
computations can be performed on the measured data after
acquisition. Tests and data can be saved and recalled, and ATS-2
measurements can be automated by macros written in the AP Basic
programming language.
§
ATS-2 can perform measurements using fast Fourier transform (FFT)
analysis. Advanced high-speed FFT analysis techniques are available,
including multitone recognition and analysis, frequency adjustment
for bin centering, synchronous FFT processing, and advanced
post-FFT analysis.
§
ATS-2 can examine an AES/EBU digital interface signal and assure
the integrity of digitally transmitted data. It can also measure and
examine the jitter in the waveform. ATS-2 can extract a variety of
statistics from a digital waveform, including the sample rate, the
interface waveform voltage, the jitter amplitude, and the active and
inactive data bits. ATS-2 also has the capability of transmitting and
receiving a full complement of AES/EBU status bits.
§
ATS-2’s sample rate may be synchronized to an external AES/EBU
signal, a square wave, or an NTSC or PAL video source.
§
ATS-2 has two auxiliary control connectors for control of external
equipment.
