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.
