Specifying Parameters: Optional parameters that are left blank are filled from left to right. Therefore, it is necessary to use the syntax DEFault to note that a particular parameter is to use the default value.

For example, to specify a sample rate other than the default, you must declare DEFault for the <readings> parameter or the <rate> parameter value you intended will be used to fill in the <readings> parameter. The command for channel 1 would appear as: CAL:GAIN1 DEF,.002. If you are calibrating the 16V range and you want to recalculate the 64V and 256V calibration constants, the command is: CAL:GAIN1 DEF,.002,ON.

Executable when initiated: NO

Coupled Command: NO

Reset (*RST) Condition: None

CALibration:SOURce

CALibration:SOURce INTernal EXTernal specifies the calibration source to be used for any subsequent gain calibrations. “EXTernal” is the default source and a voltage must be provided from an external source to the channel being calibrated.

Comments INTernal Source: The INTernal source is available only on the E1564A 4-Channel Digitizer. CAL:SOURce INTernal outputs the specified DAC voltage set by CAL:DAC:VOLT <voltage> onto the calibration bus where it is applied internally to the channels. The INTernal source is also available on the Calibration Bus Output connector.

Measuring Calibration Voltage: From the Calibration Bus Output connector, you must measure the voltage with a transfer standard (accurate voltmeter) and enter the measured value using the CAL:VALue command. The calibration gain command then sets calibration constants for the value you input assuming it is the value on the calibration bus.
