Verification Procedure

Constant Voltage Tests
NOTE
Model N6705 Service Guide
Test each output channel individually. Refer to the appropriate test
record form for the instrument settings of the model you are checking.
Voltage Programming and Readback Accuracy
Test category = performance, calibration
This test verifies that the voltage programming and measurement
functions are within specifications.
1
Turn off the DC Power Analyzer and connect a
terminals (see Test Setup A). Do not connect the load.
2
Turn on the DC Power Analyzer and program the instrument settings
as described in the test record form under "Voltage Programming &
Readback, Min Voltage". Turn the output on.
The output status should be "CV" and the output current should be
close to zero.
3
Record the output voltage reading from the DMM and the voltage
measured over the interface. The readings should be within the limits
specified in the test record form for the appropriate model under
"Voltage Programming & Readback Minimum Voltage".
4
Program the instrument settings as described in the test record form
under "Voltage Programming & Readback High Voltage".
5
Record the output voltage reading from the DMM and the voltage
measured over the interface. The readings should be within the limits
specified in the test record form for the appropriate model under
"Voltage Programming & Readback High Voltage".
6
For models N6761A, N6762A, N6781A, N6782A, and N6784A only.
Set both the voltage programming and the voltage measurement to
the low range (5.5 V for models N676xA; 6 V programming and 1 V
measurement for models N678xA). Set the instrument as described
under "Voltage Programming & Readback, Low Voltage". Repeat
step 5 for the low voltage range. The readings should be within the
limits specified under "Voltage Programming & Readback Low
Range".
7
For models N6781A, N6782A, and N6784A only. Set the voltage
programming to the 600 mV range and the voltage measurement to
the 100 mV range. Set the instrument as described under "600 mV
Programming & 100 mV Readback". Repeat step 5. The readings
should be within the limits specified under "600 mV Programming &
100 mV Readback".
8
For models N6763A – N6766A only. Set the instrument as described
under "Voltage Readback, Low Voltage". Record the voltage measured
over the interface. The reading should be within the limits specified
under "Voltage Readback Low Range".
