Data Streamers

RS3 Streamer

RS3 Block Diagram

The RS3 is a DSP card for RZ2 processors with a USB3 port for streaming high bandwidth data directly back to the computer running Synapse.

RS3 Options

By default, the RS3 uses the RZ2 device sampling rate. You can set a rate manually by clearing the Sample Rate Max check box to enable the slider. You can also select the data format and any scaling. If streaming from an analog PZ5 or PZA amplifier, the Float-32 format is recommended due to the large input range and high fidelity. If using a ZD digital headstage or PZ2 amplifier, Integer-16 format with Scaling set to 1e6 is preferred.

Segment Files Every lets you split up the data files automatically at the specified interval. The new file will begin exactly one sample after the previous file. This is useful for long recordings where the user wants access to the raw data for parallel processing before the recording is over.

Run-time Monitor adds a runtime interface that warns you of data errors and USB connection issues, and shows data storage rates.

By default the data is stored in the same block folder as the rest of the recording. Use the Store Location option to point the RS3 data files to a different path.

RS3 Runtime Interface

The runtime interface shows the current status of the USB connection. Any errors will turn the LED red and display a message in this box.

The progress bar indicates how much of the RS3 buffer is full of data that hasn't been transferred yet. This will typically be at 0% during runtime, but may spike at the beginning of the recording when the storage files are being generated, or if there are any data transfer issues to the PC.

The runtime interface also shows how much data has been recorded from the RS3 card, and an estimate of the recording time available on the hard drive.

Note

See the RS3 section of the System 3 Manual for more information about Data Streamer operations.

PO8e Streamer

PO8e Block Diagram

The PO8e is a data streaming device and requires a multi-channel data source, which you can select from the drop-down menu in the block diagram or drag the PO8e in the Processing Tree and drop it on the source gizmo. You can also choose the range of input channels.

PO8e Options

By default, the PO8e uses the RZ device sampling rate. You can set a rate manually by clearing the Sample Rate Max check box to enable the slider. You can also select the data format and any scaling. If streaming from a PZ5, due to the large input range, the Float-32 format is recommended.

Note

See the PO8e section of the System 3 Manual for more information about PO8e Interface operations.
