Note: Specifications subject to change without notice. 889094 Specifications – DaqBoard/2000 Series 7-3
Input Sequencer Applicable to DaqBoard/2000, /2001, /2002, /2004, /2005
Analog, digital and counter inputs can be scanned synchronously based either on an internal
programmable timer, or an external clock source. Analog and digital outputs can also be
synchronized to either of these clocks. Bus Mastering DMA is utilized to provide CPU and system-
independent data transfers, insuring data acquisition performance irrespective of other system
activities.
Scan Clock Sources: 2
1. Internal, programmable from 5 µs to 5.96 hours maximum in 5 µs steps
2. External, TTL level input up to 200 kHz maximum
Programmable parameters per scan: channel (random order), gain, unipolar/bipolar
Depth: 512 locations
On-board Channel to channel scan rate: 5 or 10 µs per channel, programmable
Expansion channel scan rate: 5 or 10 µs per channel, programmable
External Acquisition Scan Clock Input Applicable to DaqBoard/2000, /2001, /2005
Maximum rate: 200 kHz
Signal Range: 0V to +5V
Input Characteristics: 100 Ω series, 20 pF to common and 10 kΩ to +5V
Input protection: ±8 kV ESD clamp diodes parallel
Trigger Lev
el: TTL
Slew Rate Requirement: 14 V/µs minimum
Minimum pulse width: 50 ns high, 50 ns low
Triggering Applicable to DaqBoard/2000, /2001, /2005
Trigger Sources: 6, individually selectable for starting and stopping an acquisition. Stop acquisition
can occur on a different channel than start acquisition; stop acquisition can be triggered via modes 2,
4, 5, or 6 described below. Pre-trigger is supported with fixed or variable pre-trigger periods.
1. Single-Channel Analog Hardwa
re Trigger: Any analog input channel can be software
programmed as the analog trigger channel, including any of the 256 analog expansion channels.
Input Signal Range: Anywhere within range of the selected input channel
Trigger level: Programmable (11-bit resolution), including “window triggering.”
Hysteresis: Programmable (11-bit resolution)
Latency: 5 µs maximum
2. Single-Channel Analog Software Trigger: Any analog input channel, including any of the 256
analog expansion channels, can be selected as the software trigger channel. If the trigger channel
involves a calculation, such as with temperature, then the driver automatically compensates for the
delay required to calculate the reading, resulting in a maximum latency of one scan period.
Input Signal Range: Anywhere within the range of the selected trigger channel
Trigger lev
el: Programmable (16-bit resolution), including “window triggering”
Latency: One scan period maximum
3. Single-Channel Digital Trigger: A separate digital input is provided for digital triggering
Input Signal Range: -15V to +15V
Trigger level: TTL
Minimum pulse width: 50 ns high, 50 ns low
Latency: 5 µs maximum
