UDAQ-1216A/1416A/1416D/1432A
The UDAQ-1216A, UDAQ-1416A, UDAQ-1416D a UDAQ-1432A module series is a powerful multifunctional module for the USB interface.
The modules are fitted with 12-bit or 14-bit, providing 16 or 32 analog inputs, two analog outputs with the possibility of the signal generation, four digital inputs (they serve also as the counter inputs) and four digital outputs.
The "A" series modules provide single ended (S.E.) inputs, the "D" series modules provide either 16 S.E. inputs, or 8 differential inputs.
Control Core of the Module
The new module series is based on a modern circuit realised by the control microprocessor, efficient FPGA and two-channel USB controller.
While the microprocessor ensures the module controlling functions, the FPGA processes the data of the ADC, generates the data for the DAC and manages all data transfers between the data buffers and the USB interface.
Both microcontroller and FPGA firmware may be updated by the user.
Analog Outputs
The modules are available either without analog outputs ("AL", or "DL" version) or with two analog outputs ("AS", or "DS" version).
The analog outputs provide the data buffers and they allow the user to generate the signals with high frequency and low jitter. The data generation operates in the countinuous data block mode (the data are continuously transferred from PC) or in the cyclical mode (the module generates the block of data from the buffer; no data are transferred from the PC during the generation so the USB interface is not loaded).
The analog outputs may (besides the block mode) operate in the mode of standard software control.
The UDAQ-1216A/1416A/1416D/1432A provide
- High-impedance analog inputs (see note below)
- Programmable input ranges
- High accuracy when setting the gain of the programmable amplifier
- Analog outputs with the possibility of signal generation (AS version)
- High capacity buffer for measured data
