A/D Converters
This section covers the basic installation instructions for our A/D
converters: ADC500, ADC1000 (and PC2000), SAD500, and DAQ700.
Because A/D converter installation goes hand-in-hand with software
installation, you will find directions for installing OOIBase32
Spectrometer Operating Software included in this section. The A/D
converters we offer are:
"
ADC500 ISA-
BUS
A/D C
ONVERTER
is a 12-bit, 8-channel, single-
ended, half-length card that fits into an ISA slot in a desktop PC
and has 500 kHz sampling frequency.
"
ADC1000 ISA-
BUS
A/D C
ONVERTER
is a high-speed, 12-bit,
8-channel, single-ended, half-length card that fits into an ISA slot
in a desktop PC and has 1 MHz sampling frequency.
"
PC2000 PC P
LUG
-
IN
is an S2000 mounted onto an ADC1000
A/D card. This combination fits easily into an ISA slot in the PC;
has 1 MHz sampling frequency.
"
SAD500 S
ERIAL
P
ORT
I
NTERFACE
is a 12-bit, 8-channel A/D
converter for serial port connection for interfacing to desktop or
notebook PCs and has 500 kHz sampling frequency.
"
DAQ-700 PCMCIA A/D C
ONVERTER
from National Instruments
is a 12-bit, 16-channel, single-ended card that fits into a credit card-
size slot in a notebook PC and has 100 kHz sampling frequency.
Our software includes drivers that support the A/D converters we offer. Other A/D converters can be used with our
spectrometers if the following conditions are met:
1.
the ADC sampling rate is at least 100 kHz
2.
external triggering of the A/D conversions is supported
3.
there are a sufficient number of clocks and digital output lines to operate the spectrometer
4.
a suitable software driver has been written
5.
a suitable cable has been fabricated
Other A/D converters and software can be used to control our products; however, you will need to create your
own drivers. Contact one of our Applications Scientists for timing diagrams, pinouts, and other necessary
engineering details.
