BCRX and BCSX Files:
A BCRX file is a BioCapture recording and is the data saved from BioRadio and BioCapture software. A BCSX file is a BioCapture session and are the presets—hardware programming, digital filtering, gain and offset, display settings etc.—that can be used as a template to quickly configure the BioRadio prior to acquisition.
BioCapture and Lab Course:
BioCapture software is for research applications, while the
Lab Course software is strictly for education. We do not recommend using the
Lab Course for research purposes. The Lab Course software has a limited scope
and its capabilities are heavily dictated by the embedded lab chapters.
Dropped Packet:
A dropped packet is when the Bluetooth adapter does not receive or cannot accept data from the BioRadio. There are only a few reasons for dropped packets. Common causes include the BioRadio going out of range and not having enough battery or bandwidth to transmit correctly. Within a recording, a dropped packet is denoted by a value of 9999999.
Filtering:
Filtering is a part of signal processing where raw digital
signal data is processed to produce more certain signal data. By default,
BioCapture software provides tools for digital filtering to remove undesirable
slow-moving components of bio potentials. Common filters include a low pass and
high pass filters. A low pass filter,
for example, removes low frequency or slow components of a bio potential.
Filtering is necessary for accurate interpretation of signal data.
Inputs versus Channels:
There are two inputs—one red and one black—for each input channel. Each red input is positive and is always required. Each black input is negative and is only required for differential channels. For single ended channels, the single white REF input on the BioRadio is used in place of each black input.
Jumper Cables:
Jumper cables are for duplicating the same input signal
across multiple input channels. As the name implies, a jumper cable bridges two
separate inputs, by providing the same signal to both. Jumper cables are
convenient for creating duplicate input channels. Jumper cables are optional
accessories; contact our sales staff for more information and pricing.
Post Processing Toolbox:
The Post Processing Toolbox (PPT) is an essential analysis
module designed exclusively for saved Lab Course data files, as instructed in
the Lab Course lab chapter Procedure and Data Collection sections. The PPT is
not designed to access or analyze arbitrary ASCII files or Lab Course data
files created outside a lab chapter procedure. To use, select the applicable
lab and .data file from the drop-down menus, in the upper right hand corner of
the PPT module.
Resolution and Input Range:
Resolution is how accurately a signal is digitally
recorded. Usually, higher resolution is better, yet the higher the resolution
the more bandwidth is needed to manage signal data.
Sample Rate:
Sampling rate, in samples per second or hertz (Hz), is how
fast a signal can be digitally recorded. Usually, higher sampling rate is
better, yet the higher the sampling rate the more bandwidth is needed to manage
signal data.
