An analog-to-digital converter is necessary to
interface all Ocean Optics spectrometers to PCs. Using the ADC1000-USB to
interface the spectrometer to a PC eliminates the need for installing A/D
converters into a PC’s motherboard and for searching for available IRQs
and I/O ranges. Instead, the ADC1000-USB connects to the back of an
S2000-series Spectrometer and connects to a notebook or desktop PC via a 1-meter USB cable (included). Additionally,
the ADC1000-USB can be stacked or rack-mounted with the spectrometer in
the same housing.
-
Versatile Interface Options. Allows you to interface the spectrometer to a desktop, notebook or
handheld PC via the USB port or to a PLC via the serial (RS-232) port
-
Multiple Setup Options. The
ADC-1000 USB can be attached directly to the back of an S2000-series
Spectrometer or stacked or rack-mounted with the spectrometer in the
same housing
-
1 MHz Sampling Frequency. Enables spectrometer integration
times as fast as 3 milliseconds
-
Channel Rotator Function. Allows simultaneous acquisition of
data from up to 8 spectrometer channels
-
No External Power Requirements. When the USB port is
utilized, the spectrometer and ADC1000-USB draw their power from the
computer to which they are connected
Serial Interface Option
The ADC1000-USB also has a serial
port for interfacing the spectrometer to PCs, PLCs and other devices
that support the RS-232 communication protocol. When using the serial
port on the ADC1000-USB, a separate serial cable and power supply must
be specified, as they are not included with the ADC1000-USB. The serial
port on the ADC1000-USB can also be used to interface an S2000 to a
handheld PC running Windows CE 3.0. A different serial cable is required
for spectrometer-to-handheld PC interfacing.
Storing Wavelength Calibration Coefficients
Each spectrometer
has unique wavelength calibration coefficients that are necessary for
calibrating the wavelength of the spectrometer. With the ADC1000-USB,
you can permanently store these values onto an EEPROM memory chip in the
ADC1000-USB.
High-speed Data Processing
The ADC1000-USB has 1 MHz sampling
frequency for high-speed data processing. Because the integration time
of Ocean Optics spectrometers is a function of each A/D converter's
sampling frequency, the fastest S2000 Spectrometer integration time
possible with the ADC1000-USB is 3 milliseconds, well within the
parameters required for most applications. (At the opposite extreme, the
longest possible integration time is 60 seconds.)
Channel Rotator Function
The ADC1000's channel rotator permits acquisition of pixels from
alternating channels. For example, acquisition with a triple-channel
spectrometer can be configured so that Pixel #0 is acquired from the
master channel, Pixel #1 is acquired from the first slave channel, and
Pixel #2 from the second slave channel. As the sequence repeats, Pixel
#3 is acquired from the master channel, and so on. As a result, spectra
are acquired from multiple spectrometer channels simultaneously, making
the ADC1000 ideal for applications involving pulsed light sources and
transient spectral events. The data collected when using the
multi-channel scanning capability of the ADC1000-USB can be separated
into individual spectra by a variety of Ocean Optics software products.
Operating Systems
When using the USB port on the ADC1000-USB to
interface the spectrometer to a desktop or notebook PC, you must have a Windows 98/Me/2000/XP
operating system. Using
the serial port on the ADC1000-USB to interface the spectrometer to a
desktop or notebook PC requires any 32-bit Windows operating system.
