3Prepare the E1564A for calibration:

•Set the channel’s range: VOLT<channel>:RANG <range>

•Set the calibration source to internal: CAL:SOUR INT

•Set the CAL DAC output voltage:CAL:DAC:VOLT <voltage> (see Table E-2 for <range> settings and CAL DAC <voltage> setting)

4 Note the voltmeter reading from the calibration bus output.

5Send the value measured from the calibration bus output as the parameter for the calibration value: CAL:VAL <voltage>

6Perform the adjustment by sending CAL:GAIN<channel> (adjusts each channel in about 5 seconds).

7Send SYST:ERR? and read the result to verify the calibration command was successful.

8Repeat Steps 3 through 7 for ranges and inputs in Table E-2.

9 Repeat steps 3 through 8 for channels 2, 3 and 4.

NOTE Valid calibration input values sent to the digitizer are 0.85 to 0.98 of Full Scale for the range being adjusted. The CAL:VAL <input voltage> parameter must equal the actual input value. For example, if you input 0.9V to calibrate the 1V range (instead of 0.95), send CAL:VAL 0.9 to the digitizer prior to the CAL:GAIN<channel> command.
