APIB
The ATS con trol soft ware on the PC com mu ni cates with the ATS-2
hard ware in one of two ways:
§
USB-APIB
Introduced with the release of ATS version 1.6, the USB-APIB
adapter provides a convenient USB interface to the instrument. USB
operation is not supported by earlier versions of ATS.
§
APIB
APIB (Audio Precision Interface Bus) is a proprietary bus
interconnection that requires a dedicated APIB cable and
PC-mounted APIB interface card or adapter. APIB interfaces are
available as PCI, PCI Express or PCMCIA-compatible devices.
The USB-APIB adapter or APIB in ter face are spec i fied at the time your
sys tem is or dered. An in ter face adapter kit can also be or dered sep a rately.
GPIB
When or dered in the op tional GPIB con fig u ra tion (ATS2G), ATS-2 can
also be con trolled by the in dus try-stan dard IEEE 488.2 Gen eral Pur pose
In ter face Bus (GPIB). See Chap ter 7 for more in for ma tion 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.
