Taking EMG Measurements
The SX230 is an active EMG sensor
designed and manufactured by Biometrics and has been developed with ease of
use and superb quality of signal in mind.
The SX230 may readily connect to either the DataLOG, DataLINK or K800. These instruments are general purpose data collection devices and may collect signals from a wide range of sensors simultaneously with EMG. This is ideal for correlation of muscle activity with other physiological parameters.
Using the DataLOG or DataLINK the stored data may be displayed and analyzed within the Biometrics software, or the raw data may be saved as an ASCII or a standard Sound Wave file for import into many other analysis programs such as Microsoft Excel or Cool Edit
The contact switch assembly type no. FS4 is readily interfaced to both the DataLOG and DataLINK giving the user the ability for example to monitor heel contact & toe off during EMG gait trials.

EMG and the DataLOG
The DataLOG offers the user the ability to collect EMG and other data reliably from up to 32 channels simultaneously in a truly portable configuration. When more than 8 channels are required 2, 3 or 4 DataLOGs may be synchronised using a single wireless Bluetooth connection providing options for 16, 24 and 32 analog channels. The DataLOG Display & Analysis software allows for an unlimited number of real date and time stamped data files to be opened simultaneously >and the time axis may be tracked across all files allowing display & analysis for a large number of channels.
The capabilities offered to the user of EMG measurements using the DataLOG is unrivalled even by much more costly systems.
EMG and the DataLINK
The DataLINK provides the user the ability to collect EMG and other data simultaneously with real time display and real time data analysis. The usefulness and simplicity of this accurate real time display and real time feedback is emphasized for both a research and educational setting.
The DataLINK Display & Analysis software allows for:
- 8 analog channels and 5 digital channels to be displayed and analyzed real time
- real time display and real time scaling in engineering or SI units
- adjustable real time audible and visual alarms for any channe
- 8, 16, 24 or 32 analog channels
- Readily synchronised with other systems
