Calibrating the CIO-DAS08/JR-AO
You can quickly calibrate the CIO-DAS08/JR-AO using InstaCal. The CIO-DAS08/JR has a fixed input range
and does not have any input amplification or gain/offset compensation electronics. When using the optional
Universal Library, all compensation for gain/offset errors is done in software after the signal is acquired. The
gain and offset calibration factors are stored in the CB.CFG configuration file and applied to the analog
samples after they are acquired. Run the
Calibrate option from InstaCal to set the calibration factors.
