2. Connect the Bias Output Voltage connector on the rear of the 8003 to the vertical input of the
oscilloscope. Set the oscilloscope as follows:
Volts/Div: 5V /Div
Time/Div: 200
µ
µµ
µ
s/Div
Triggering: AC/Auto/Int
3. Ground the oscilloscope input and center the trace.
4. Select DC coupling on the oscilloscope.
5. Set the Bias Output Voltage on the 8003 to + 10V.
[DEFINE] [BIAS VOLTAGE] [1] [0] [S]
6. Check that the trace on the oscilloscope moves up 2 divisions (+10V) from center screen during
the sweep, and back to center (0V) on retrace.
7. Set the Bias Voltage Output on the 8003 to -10V.
[DEFINE] [BIAS VOLTAGE]
[-] [1] [0] [S]
8. Check that the trace on the oscilloscope moves down 2 divisions (-10V) from center screen during
the sweep, and back to center (0V) on retrace.
4.3.9 DAC Output Connector Check
Not Presently Used.
4.3.10 RGB Video Output Connector Check
Connect the 8003 Op 02 RGB Video Output to the High Resolution Color Display Monitor and display
a stable color picture that duplicates the display on the 8003.
4.3.11 SUMMARY
This completes the performance test and calibration tests for the 8003 Precision Scalar Analyzer and its
sensors. If the instrument has performed as described in this chapter, it is correctly calibrated and within
specifications.
If the instrument fails to meet any of the criteria defined in the tests, refer to the calibration and/or
maintenance sections of the 8003 Maintenance Manual (P/N 20791-001).
