ADC1000-USB A/D Converter

The ADC1000-USB A/D Converter is a plug-and-play high-speed A/D converter designed for hassle-free instrument-to-PC interfacing.

  • Fast USB port interface

  • Acquires data from up to 8 channels at once

  • Integration time as fast as 3 ms

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.

The ADC1000-USB retails for $751.

  • 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.
