Step 2: Voltage measurement calibration
Follow these steps to calibrate voltage measurements.
summarizes calibration
voltages and commands.
1. Put the unit into the DC mode with this command:
:SOUR1:FUNC:SHAP DC
2. Send the following command to select the 10V range:
:SENS1:VOLT:RANG 10
3. Disconnect all signal cables from the testhead.
4. Send the following commands in order:
:DIAG:KEIT:FCON:HI ON
:DIAG:KEIT:FCON:LO ON
:SENS1:VOLT:POL NEG
:CAL:PROT:SENS1 0
:SENS1:VOLT:POL POS
:CAL:PROT:SENS1 0
:DIAG:KEIT:FCON:LO OFF
5. Connect the calibrator to the Model 2520 testhead VOLTAGE SENSE jacks, as
shown in
.
6. Set the calibrator voltage output to -10.000V, and turn on its output.
7. Send the following command to calibrate the +10V point:
:CAL:PROT:SENS1 10
8. Reverse the calibrator HI and LO connections.
9. Send the following commands to calibrate the negative full-range voltage point:
:DIAG:KEIT:FCON:HI OFF
:DIAG:KEIT:FCON:LO ON
:SENS1:VOLT:POL NEG
:CAL:PROT:SENS1 -10
:DIAG:KEIT:FCON:LO OFF
10. Repeat steps 2 through 9 for the 5V range using
as a guide. Be sure to:
• Select the 5V range using the :SENS1:VOLT:RANG 5 command.
• Send the appropriate calibration voltage values with the :CAL:PROT:SENS1
<Voltage> command.
