CALibration:STORe

CALibration:STORe writes the calibration constants to non-volatile RAM after calibration has been completed.

NOTE The FLASH and CAL CONSTANTS switches must be set to the “Write

Enable” positions before calibration constants are stored in RAM.

Executable when initiated: NO

Coupled Command: NO

Reset (*RST) Condition: None

CALibration:VALue

Parameters

Comments

CALibration:VALue <voltage> specifies the voltage value actually applied to the channel for calibration. This value informs the digitizer what voltage is either being placed on the front panel input connector (CAL:SOURce EXTernal) or the value being generated by the internal DAC (E1564A 4-Channel Digitizer only) and being output onto the calibration bus.

Source Maximum Voltages: The maximum voltage from an external source used to calibrate the 16V range is 15.68V or 98% of full scale. The maximum voltage attainable from the E1564A internal DAC is 15V.

Using the Internal DAC: The internal DAC on the E1564A can be used for the calibration source when CAL:SOURce INTernal is specified. The output level of this DAC is specified with CAL:DAC:VOLTage. The actual output level must be measured with a voltmeter by the person doing the calibration. That measured value is the value used for the <voltage> parameter of the CAL:VALue command. The voltage can be measured across pins 5 (high) and 9 (low) of the Calibration Bus Output (D-subminiature) calibration bus connector.

Maximum Output Levels: The maximum output levels are limited to the levels shown in the following table. These are the E1564A DAC voltages recommended for calibrating each range. The values are approximately 98% of full scale (except for the 16V range which the internal E1564A’s DAC has a maximum output of ±15V.
