To duplicate a waveform, select the waveform (channel) and click “Edit > Duplicate Waveform”.
For Windows versions of AcqKnowledge older than version 4.0:
When selecting the waveform, BIOPAC recommends choosing “Edit > Select All” so that the full waveform is selected and not a partial waveform. If only a section of the waveform is highlighted, only the highlighted area of data will be duplicated.
For AcqKnowledge version 4.0 and above to mimic earlier behavior (copying only a piece of a waveform), use the I-beam tool to select the area to be duplicated, type control-c (command-c on a Mac) or choose “Edit > Copy”. Then choose “Edit > Insert Waveform”.
The NICO Smart Amplifier is specifically designed to measure thoracic impedance for performing noninvasive cardiac output measurements. The amplifier terminates in two connectors for impedance (Z) and its derivative (dZ), and has a 3 m cable that connects directly to an AMI100D Amplifier Input Module. Use with EL500 series disposable electrodes and LEAD131 for a four-spot […]
NIRS and CNAP—Pairing great tools for great data Cerebral hemoglobin concentration (blood mass in the brain) is frequently measured in the prefrontal cortex, and systemic arterial blood pressure is known to be a variable factor based on the hemoglobin concentration. A leg pressure cuff was used to constrict and release blood flow to create a […]
BIOPAC’s just released Introductory ECG Guide addresses fundamental to advanced concerns to optimize electrocardiography data recording and analysis. Topics include: ECG Complex; Electrical and Mechanical Sequence of a Heartbeat; Systole and Diastole; Configurations for Lead I, Lead II, Lead III, 6-lead ECG, 12-lead ECG, precordial leads; Ventricular Late Potentials (VLPs); ECG Measurement Tools; Automated Analysis Routines […]
