Calibration
Important The Agilent SAS can only be calibrated in Fixed mode. Mode switching is accomplished over the
GPIB bus via the SCPI CURRent:MODE command.
The Agilent SAS may be calibrated either from the front panel or from a controller over the GPIB. The procedures given
here apply to both models. The recommended calibration interval is once a year. Note that these instructions do not include
verification procedures. If you need to perform verification as a prerequisite to or as part of your calibration procedure, see
“Verification”.
Test Equipment Required
The equipment listed in Table B-1, or equivalent, is required for calibration.
General Procedure
Because the Agilent SAS output must be enabled during calibration, voltages or currents
hazardous to personnel and/or damaging to equipment can appear at the output terminals.
Parameters Calibrated
The following parameters may be calibrated:
•
Output voltage.
• Output voltage readback.
• Overvoltage protection (OVP).
• Output current.
• Output current readback.
You do not have to do a complete calibration each time. If appropriate, you may calibrate only the voltage or current and
proceed to "Saving the Calibration Constants".
Figure B-1 shows the test setups required for voltage and current calibration.
