DM34216HR
PCIe/104 1–25 MHz A/D Digitizer
|
| Rugged IDAN configurations available |
Description
The DM34216HR dataModule is a rugged high speed data acquisition (DAQ) module in the PCIe/104 format which boasts four 16-bit 25 MHz A/D converters.
This module provides 4 single-ended analog input channels with software-selectable input ranges and input impedances. Each input channel has a dedicated ADC, permitting simultaneous sampling of the inputs. Additionally, each channel also has a dedicated DMA channel, which ensures the ability for the host controller or a DSP to continuously collect data from all four channels across the PCIe x4 interfaces.
The DM34216HR also features 32-bit advanced DIO with peripheral output capabilities including a quad PWM and external clocking. The SyncBus permits multiple DAQ cards to be synchronized within the system.
When used with RTD’s SPM34CP high-performance DSP, data can be transferred directly to the DSP’s memory using a CPU’s PCIe connection.
