The DaqBoard/3000USB Series boards feature a 16-bit/1-MHz A/D converter, 16 analog input channels
[user expandable up to 64 for the /3031USB and 3035USB models], up to four 16-bit/1-MHz analog
outputs [for models /3001USB and /3031USB], 24 high-speed digital I/O channels, 2 timer outputs, and
four 32-bit counters.
All analog I/O, digital I/O, and counter/timer I/O can operate synchronously and simultaneously,
guaranteeing deterministic I/O timing amongst all signal types. The DaqBoard/3000USB Series boards
include a high-speed, low-latency, highly deterministic control output mode that operates independent of
the PC. In this mode both digital and analog outputs can respond to analog, digital and counter inputs as
fast as 2µsec.
Other Hardware Features Include:
o
Encoder measurements up to 20 MHz, including Z-channel zeroing
o Frequency and Pulse-width measurements with 20.83 nsec resolution
o
A Timing mode that can measure the time between two counter inputs to 20.83 nsec resolution
o Self-calibration
The DaqBoard/3000USB series offers up to 4-MHz scanning of all digital input lines. Digital inputs and
counter inputs can be synchronously scanned [along with analog inputs] but do not affect the overall A/D
rate because they use no time slot in the scanning sequencer. For example, one analog input can be scanned
at the full 1-MHz A/D rate along with digital and counter input channels. The 1-MHz A/D rate is
unaffected by additional digital and counter channels.
An additional 48 single-ended [or 24 differential] analog input channels are included with models
/3031USB and /3035USB through their J5 and J6 headers (two of the four the onboard 40-pin headers,
see
pinout chapter 2 ). Typically, a CA-248 cable is connected to the header to provide a DB37 connection
option. The CA-248 cables have a 40-pin header at one end and a male DB-37 connector at the other. A
pinout for the CA-248 is provided in Chapter 2.
With the boards’ 1-MHz aggregate sample rate, users can easily add multiple analog expansion channels to
the /3031USB and /3035USB boards and still have enough bandwidth to have a per-channel sample rate in
the multiple kHz range.
