Analog Channel Expansion
Adding additional analog input channels for the OMB-DAQ-3000 is easy using the optional OMB-PDQ30 expansion module. The OMB-PDQ30 connects to the OMB-DAQ-3000 by either plugging directly into the expansion connector or via a cable (OMB-CA-96A) if distance is required between the two units. The OMB-PDQ30 provides an additional 48SE/24DE analog inputs or 24 differential thermocouple inputs, software-configured on a per-channel basis. The total channel capacity with a OMB-PDQ30 attached is 64 single-ended or 32 differential inputs. The measurement speed of OMB-PDQ30 channels is the same 1 Msample/s as with the OMB-DAQ-3000 channels. When configured to measure thermocouple channels, the system sample rate is typically 50 Hz to 10 kHz per channel. This reduction in sample rate ensures that temperature measurements are accurate, low noise and stable.
Synchronous I/O
The OMB-DAQ-3000 can make analog measurements and read digital and counter inputs, while synchronously generating up to four analog outputs as well as digital pattern outputs. Digital and counter inputs do not affect the overall A/D rate because they use no time slot in the scanning sequencer.
Input Scanning
The OMB-DAQ-3000 has several scanning modes to address a wide variety of applications. A 512-location scan buffer can be loaded by the user with any combination of analog input channels. All analog input channels in the scan buffer are measured sequentially at 1 μs per channel. The user can also specify that the sequence repeat immediay or repeat after a programmable delay, from 0 to 19 hours, with 20.83 ns resolution. In either of the two synchronous modes, the digital inputs and/or counter inputs are read with deterministic time-correlation to the analog inputs. In the once-per-scan mode, all of the enabled digital inputs and counter inputs are read during the first analog measurement of an analog input scan sequence. The advantage of this mode is that the digital and counter inputs do not consume an analog input time slot and therefore do not reduce the available bandwidth for analog input measurements.
Output Timing
The digital and analog outputs on the OMB-DAQ-3000 can be updated asynchronously or synchronously in several modes. In asynchronous mode, digital and analog outputs can be updated before, during or after an analog input sequence. The maximum update rate in this mode is non-deterministic and is entirely dependent on the PC processor speed, the operating system and programming environment. In synchronous output modes, outputs can be updated continuously from the PC or in response to an input from an analog channel, digital channel or counter channel. When updated from the PC, the user can specify the rate at which the output is updated in 20.83 ns intervals. Outputs are updated synchronously at a maximum rate of 1 μs.
Analog Output (OMB-DAQ-3000 and 3001 Only)
Two or four 16-bit, 1-MHz analog output channels are built into the OMB-DAQ-3000 with an output range from -10 V to +10 V. The maximum rate at which analog outputs can be updated depends on several factors, including the speed of the USB port. Typically, with the A/D operating at full 1 Mreading/s rates, one analog output can be updated continuously from PC memory at 1 MHz, or two analog outputs at 500 kHz or four analog outputs at 250 kHz.
Digital I/O
Twenty-four TTL-level digital I/O lines are included in the OMB-DAQ-3000. Digital I/O can be programmed in 8-bit groups as either inputs or outputs and they can be scanned in several modes (see Input Scanning). Ports programmed as inputs can be part of the scan group and scanned along with analog input channels, or they can be asynchronously accessed via the PC at any time, including when a scanned acquisition is occurring. Two synchronous modes are supported when scanned along with analog inputs. In one of these modes, digital inputs are scanned at the start of each scan sequence, which means the rate at which they are scanned is dependent on the number of analog input channels and the delay period. If no analog inputs are being scanned, the digital inputs can be scanned at up to 12 Msamples/s. The low-latency digital output mode allows a digital output to be updated based on the level of an analog, digital or counter input. In this mode, the user associates a digital output bit with a specific input and specifies the level of the input where the digital output changes state. The response time in this mode depends on the number of input channels being scanned and can typically be in the range of 2 to 6 μs.
Pattern Generation
Two of the 8-bit ports can be used to generate a 16-bit digital pattern at up to 1 MHz. The digital pattern can be read from PC RAM or a file on the hard disk. Digital pattern generation is clocked in the same four modes as was described withanalog output.
Counter Inputs
Four 32-bit counters are built into the OMB-DAQ-3000. Each will accept frequency inputs of up to 20 MHz, and each counter channel can be configured in a variety of modes, including counter, period, pulse width, time between edges, or multi-axis-quadrature encoder. The counters can concurrently monitor time periods, frequencies, pulses, and other event-driven incremental occurrences from encoders, pulse generators, limit switches, proximity switches, and magnetic pick ups. As with all other inputs to the OMB-DAQ-3000, the counter inputs can be read asynchronously under program control, or synchronously as part of an analog and digital scan group based either on an internal programmable timer or on an external clock source. The OMB-DAQ-3000 supports quadrature encoders with up to 2 billion pulses per revolution, 20 MHz input frequencies, and x1, x2, x4 count modes. With only A phase and B phase signals, 2 channels are supported. With A phase, B phase, and Z index signals, 1 channel is supported. Each input can be debounced from 500 ns to 25.5 ms (total of 16 selections) to eliminate extraneous noise or switch-induced transients. Encoder input signals must be within -15 V to +15 V and the switching threshold is TTL (1.3 V).
Timer Outputs
Two 16-bit timer outputs are built into the OMB-DAQ-3000, each capable of generating different square waves with a programmable frequency range from 16 Hz to 1 MHz.
