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.
Output voltage near 0 V.
Output current near 0 A.
3. Record the voltage reading on the DMM (Vlo) and the voltage
reading on the front panel display (Vfplo).
Readings within low voltage limits
(see table B-2, B-3, B-4)
4. Set the output 1 voltage to 15 V. Output voltage near 15 V.
5. Record the voltage reading on the DMM (Vhi) and the voltage
reading on the front panel display (Vfphi).
Readings within high voltage limits
(see table B-2, B-3, B-4)
Steps 6-10 apply to Agilent 66309B/D output 2 only
6. Turn off the dc source and connect a DMM to the output 2 terminals.
7. Turn on the dc source with no load on output 2. Select output 2 and
set the voltage to 0.01 V and the current to 1.5 A. Press Output
On/Off to enable the output.
Output voltage near 0 V.
Output current near 0 A.
8. Record the voltage reading on the DMM (V2lo) and the voltage
reading on the front panel display (V2fplo).
Readings within low voltage limits
(see table B-4)
9. Set the output 2 voltage to 12 V. Output voltage near 12 V.
10. Record the voltage reading on the DMM (V2hi) and the voltage
reading on the front panel display (V2fphi).
Readings within high voltage limits
(see table B-4)
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 Normal Result
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.
CURR:DET DC
3. Set the output 1 voltage to 5 V and the current to 0 A. Press
Output On/Off to enable the output.
Output current near 0 A.
4. Divide the voltage drop across the current monitor by its resistance
to convert the value to amperes. Record this value (Ilo).

(see table B-2, B-3, B-4)
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).
