Resonant Scanning NI DAQ Configuration¶
Note
For new installations, Vidrio recommends the use of vDAQ. vDAQ is a powerful all-in-one microscope controller with a stream lined user experience, that supports a wider feature set than traditional NI hardware.
ScanImage uses the NI PXIe platform for data acquisition. This platform consists of a NI PXIe and several extension cards. The chassis connects to the computer via an MXI link.
The recommended PXIe chassis is NI-PXIe 1073.
ScanImage uses the NI FlexRIO platform to achieve the high sampling speeds required for resonant scanning. A FlexRIO device consits of an PXIe FPGA board and an adapter module, which provides the analog frontend. The following modules are supported:
FPGA module |
Adapter Module |
The following X-series data acquisition hardware is required for controlling scanners and additional optical devices:
Peripheral |
DAQ |
Resonant and Galvo Scanners |
|
Beam Modulator (optional) |
|
FastZ (optional) |
|
Second scan path for photostimulation (optional) |
Note
An NI X-series board features one single ‘timing engine’ for all analog outputs on the board. This means that all analog outputs on the board share the same start trigger and sample clock. It is therefore not possible to combine devices that require different triggers and clocks on the same DAQ board. Consequently, scanners, fastZ and beam devices each require their own DAQ board.
