Comments Steps Before Executing a Gain Calibration: The following steps must be

completed prior to executing a gain calibration:

1Set the digitizer to the desired range and filter on the channel you want to calibrate with VOLTage[<channel>]:RANGe <range> and INPut[<channel>]:FILTer:FREQ <freq> and :FILTer:STATe ONOFF.

2Enable calibration with CALibration:STATe ON and specify the calibration source with CALibration:SOURce.

3Specify a calibration value for the channel you are calibrating. The value must be between 85% and 98% of either a positive full scale reading or negative full scale reading. The ideal calibration value is

98% of positive or negative full scale (see CALibration:DAC: VOLTage).

4The calibration voltage must be applied to the input connector if CALibration:SOURce EXTernal is used. You must enter the external calibrator voltage value with CAL:VALue when an external calibration source is used.

5The E1564A 4-Channel Digitizer automatically applies the DAC voltage to the internal calibration bus when CALibration: SOURce INTernal is used. You must measure the DAC voltage at the Calibration Bus Output Connectors (CAL-L and CAL-H) (for CAL:SOURce INTernal) and enter that value with CAL:VALue.

Sampling Rate: The number of readings and sampling rate will default to 100 readings and 0.001 second sampling rate, respectively, to provide averaging over an integral number of either 50 Hz or 60 Hz power line cycles. This allows calibration to cancel out any noise that is periodic with the power supply.

64V and 256V Ranges Calibrated Indirectly: The 64V and 256V ranges are

calibrated indirectly when the 16V range is calibrated and the ON (1) parameter is set. If the OFF (0) parameter is active, only the 16V range is calibrated and the 64V and 256V ranges retain their old calibration constants. This boolean ON/OFF parameter is checked and used only when calibrating the 16V range. It is ignored when calibrating any other range.

Calibrate Lower Ranges First: All lower ranges (0.0625V through 4.0000V) must be calibrated before calibrating the 16V range and calculating new calibration constants for the 64V and 256V ranges. The effects of the attenuators and amplifiers on the gain calibrations for the lower ranges are extrapolated to derive a gain constant for the 64V range and another for the 256V range.
