Biopotential amplifier signal validation

It is possible to validate the signals coming from any BIOPAC biopotential amplifier* by using a CBLCALC Calibration Cable. The cable connects to the front of the amplifier and the UIM100C Analog Output 0 or 1, or to a known signal source in the ±10 V range.
Create a stimulus signal using AcqKnowledge and monitor the output of the amplifier that the CBLCALC is connected to. The CBLCALC will attenuate the output signal (1/1,000), and the amplifier will amplify the signal by the gain setting.
For example, if the stimulus signal is 1 V and the gain setting is 1,000, the corresponding signal from the amplifier should be 1 V. The signal can be used for amplifier validation and signal calibration.
If the signal is significantly different from the source signal level, contact BIOPAC for further assistance.
* Note: DA100C requires CBLCAL, not CBLCALC.
