Verification and Calibration - B

Voltage Programming and Measurement Accuracy

This test verifies the voltage programming, GPIB measurement, and front panel meter functions. Values read back over the GPIB should be the same as those displayed on the front panel. Measure the dc output voltage at the output terminals. Make sure that the sense terminals are directly jumpered to the

output terminals on both outputs 1 and 2.

Action

Normal Result

1.Turn off the dc source and connect a DMM to the output 1 terminals.

2.Turn on the dc source with no load on output 1. Select output 1 and set the voltage to 0.01 V and the current to 3 A. Press Output On/Off to enable the output.

3.Record the voltage reading on the DMM (Vlo) and the voltage reading on the front panel display (Vfplo).

4.Set the output 1 voltage to 15 V.

5.Record the voltage reading on the DMM (Vhi) and the voltage reading on the front panel display (Vfphi).

Output voltage near 0 V.

Output current near 0 A.

Current Programming and Measurement Accuracy

This test verifies the current programming and measurement. Connect the appropriate current monitor (see table B-1) as shown in figure B-1A.

Current Programming and Measurement (High Range on Agilent 66311B/D, 66309B/D)

Action

1.Turn off the dc source and connect the DMM and current monitor to output 1 as shown in figure B-1A. Then turn on the dc source and select Output 1.

2.Turn on the dc source, access the Input menu, and set the current sense detector to DC.

3.Set the output 1 voltage to 5 V and the current to 0 A. Press Output On/Off to enable the output.

4.Divide the voltage drop across the current monitor by its resistance to convert the value to amperes. Record this value (Ilo).

5.Set the output 1 current 3 A.

6.Divide the voltage drop across the current monitor by its resistance to convert the value to amperes. Record this value (Ihi). Also record the current reading on the front panel display (Ifphi).
