Modular construction...extreme flexibility

MP systems offer features to support nearly every physiological recording scenario. The following advanced features apply to the application you selected.

If you don't see an Advanced Feature that interests you, please contact BIOPAC so we can identify the best solution for your particular need.

Median and Mean Frequency Analysis

Analysis of EMG signals in the frequency domain can provide useful insight into the nature of the EMG data. The frequency spectrum data may be used to generate other measures associated with EMG frequency analysis. Select an area of EMG data and use the Fast Fourier Transform function to perform a linear magnitude FFT on the […]

Motor Unit Action Potential

Motor unit action potentials (MUPs) are the summation of all single-fiber potentials innervated. Evaluate waveshapes of MUPs and measure amplitude, rise time and duration using the EMG100C Electromyography Amplifier with concentric needle electrodes (EL451).

Single-Fiber EMG

Record and analyze single-fiber potentials with a concentric needle electrode (EL451). Set the EMG100C to a 100 Hz – 5 kHz recording bandwidth. For improved rejection of low frequency background activity of distant fibers, run the data through a real-time 500 Hz HP filter in AcqKnowledge. The TSD150 series of Active Electrodes also include adapters […]

Surface EMG

BIOPAC offers a variety of surface EMG (sEMG) recording and analysis options. sEMG data can be recorded with reusable or disposable surface EMG electrodes sent to a wired, wireless, or MRI-specific EMG amplifier. Hardware solutions range from single channel tethered EMG to 32 channel wireless, telemetered and logged data. Easily combine surface EMG with visual, […]

Synchronize With Video Capture

Media functionality provides tight synchronization between a video recording of a subject and their physiological data.
