VREF, excitation voltage and reference voltage refer to the same concept. This is the voltage the DA100C series amplifier provides for connected transducers that need to be powered. The excitation voltage level (peak-to-peak, i.e. the absolute difference between the value for VREF- and VREF+) will influence the readings obtained from the transducer. Therefore, this voltage must be known for the purposes of calibration. The Reference Calibrator for DA100C (REFCAL) can be used. The REFCAL plugs into the DA100C and directs the reference voltage setting to the DA100C output. The REFCAL makes it very easy to adjust the reference voltage of the DA100C to suit your transducer. Alternatively, a voltmeter can be used.
Use this DSUB9 to RJ11 jack Output Adapter to map the analog output of an MP36 or MP36R to an RJ jack; allows stimulators designed with HLT-compatible connections to be connected to MP36/36R units. Control the STMTHERM, or other stimulators that have RJ11 input cables.
Recent Studies using BIOPACs MP-Series (MP160, MP150) data recorders, ECG Amplifiers, and BioNomadix Wireless recorders: Singing style to infants Mothers around the world sing to infants, presumably to regulate their mood and arousal. Lullabies and playsongs differ stylistically and have distinctive goals. Mothers sing lullabies to soothe and calm infants, and playsongs to engage and […]
Alex Dimov, BIOPAC Sales Executive, was interviewed at the Neuromarketing World Forum by Inside Marketing to discuss how virtual reality can improve marketing research. Alex explains how VR can be used to present virtual iterations of a product to save time and money, and notes that measuring physiological responses adds lots of information for product and messaging […]
