Although the maximum rate is divided by the number of DACs being used, all DACs’ outputs update simultaneously on the hardware clock’s tick - all four DACs can output simultaneous data at 250 kilosamples/second, or one at 1 MHz! All the data is transfered by DMA to minimize CPU utilization, with IRQs so applications can send additional buffers of data as needed. This feature allows one or more of the DACs to output voltage levels at a software-configurable rate as high as 1 million samples/second. The “FDS” model includes a new DMA-driven hardware-timed buffered DAC output feature, “DAC Waveform Streaming”. The digital inputs implement various “alternate functions” including external trigger of ADC or DAC.įour analog outputs with uni- and bipolar 5 and 10 volt ranges and a ☒.5V range round out the feature set. Bits 0-7 form one group, and bits 8-15 can be configured for input/output mode individually. Sixteen digital I/O configured in 9 “I/O Groups” as input or output per group. Each channel can be independently software configured to accept any input ranges. The M.2-ADIO16-8F is a 16-bit resolution A/D & D/A board with 16 flexible digital I/O, with 8 single ended or 4 differential analog inputs. The M.2-ADIO16-8F is an ideal solution for adding high-speed analog I/O capabilities to any computer with an M.2 slot. Support for Wind River VxWorks (call for ordering information).Extended temperature operation (-40☌ to +85☌).Designed, made, supported, and manufactured in the USA.Available in PCI Express Mini (mPCIe) form!.16 Digital lines with alternate functions including ADC and DAC Trigger.“FDS” model allows hardware-timed DMA+FIFO (8 kSamples) waveform streaming on up to four DACs.Independently Programmable Output Ranges:.8 Pseudo-differential (Single-Ended) or 4 Differential Inputs.Flexible, Software Configured Functionality.Differential Input Voltage Ranges from ☐.64V to ☒4.576V.16-Bit 1MSPS Complete Data Acquisition System.M.2 2260/2280 “B/M” size Card with latching I/O connectors.So I force the generation to 0Volt rather than just stopping the task. I want to control the value generated by the board at any time to avoid damaging the device I send the signal to. The AO starts generating a constant value of 0Volt. P.S.: when the switch is set to OFF, the AO task is not completely stopped. Why is it working right after running the VI, but not after using the switch on the front panel? The AO task begins generating samples right after starting the task, without waiting for the next rising edge of the counter output.Ĭould anyone help me to understand what is going on, please? BUT! After turning the switch to OFF and then back to ON, the signals are not synchronized anymore. The two signals being generated are perfectly synchronized (AO and Ctr). When I run the VI, the very first start of the AO is indeed triggered by the counter. I would like to use this counter as the Start Trigger for the AO so that, when the switch on the front panel is set to ON, the AO task waits for the next rising edge of the counter output to start the generation. The generation can be stopped and (re-)started at any time using a switch on the front panel.Īside from this AO Channel, there is a counter. The regeneration is enabled so that the signal is generated continuously. In the VI I attached to this post, I have one Analog Output channel that generates a predefined signal stored in the board memory. I am currently using a PCI-6120 with a BNC-2120.
