RHD2164Device

A Bonsai source that wraps a RHD2164 device.

Inputs

None

Outputs

A RHD2164DataFrame that contains one or more samples from all 64 analog inputs and auxiliary channels.

  • This type is a buffered set of the Device To Host Data Frame specified on the RHD2164 device datasheet.

  • The number of samples in each output is determined by the BlockSize parameter

Configuration

Configuration is performed using the property pane which contains the following options.

Name

Type

Description

EnableStream

boolean

The numbEnable the device data stream

BlockSize

integer

The number of 64-channel ephys + auxiliary channel samples that are included in each RHD2164DataFrame. Larger numbers result in less overhead at the cost of larger buffering latencies.

AnalogHighCutoff

enum

Select a high-frequency cutoff from allowable options. This filtering is performed prior to analog to digital conversion.

AnalogLowCutoff

enum

Select a low-frequency cutoff from allowable options. This filtering is performed prior to analog to digital conversion.

DSPCuttoff

enum

Select the low-frequency cutoff for the integrated digtial offset removal filter. This fitering is performed following analog to digital conversion.

EphysDataFormat

enum

The format of the ephys samples within the RHD2164DataFrame.

  • Unsigned: raw 16-bit unsigned integer conversion results.

  • TwosCompliment: raw 16-bit signed integer conversion results.

  • MicroVolts: 32-bit floating-point voltages.

AuxDataFormat

enum

The format of the auxiliary samples within the RHD2164DataFrame.

  • Unsigned: raw 16-bit unsigned integer conversion results.

  • Volts: 32-bit floating-point voltages.
