AP033 Active Differential Probe
13. In the CHANNEL section of the oscilloscope, set the probe offset to +0.4000 V by rotating the
OFFSET knob (or with the OFFSET knob linked to the COUPLING menu when using the older
software.)
14. Allow 10 seconds for the AP033 to stabilize.
15. Note the amplitude of the trace from center screen.
16. Adjust Offset Cal (R330) to position the trace to approximately ? the amplitude from center
screen noted in the previous step. This amplitude should be within 10 mV of center screen.
Note this value.
17. Again, remove the dual banana plug adapter from the output of the DC voltage source and
reconnect it, with the pins reversed. The plug corresponding to the BNC shield (marked
“Ground”) should now be connected to the – (Common) Output connector.
18. Set the probe offset to – 0.4000 V.
19. Allow 10 seconds for the AP033 to stabilize.
20. The trace should be offset from the center line by the same amplitude but opposite polarity of
the value noted in step 16.
21. Repeat steps E-12 through E-20 as necessary until the errors at +0.4 V and at – 0.4 V are
approximately equal and within 10 mV of center scale. Reverse the polarity of the dual banana
plug adapter at the output of the DC voltage source, and the corresponding probe offset value
with each repetition.
22. Disconnect the cable from the DC Voltage Source. Keep the AP033/AP034 Calibration Fixture
connected to the AP033 for the next step.
F. Adjust GAIN (R322C)
1. Set the AP033 offset to 0.000 V by rotating the OFFSET knob in the CHANNEL section of the
oscilloscop e (or with the OFFSET knob linked to the “COUPLING” menu when using the older
software versions). Make sure the probe is still set to /1 Atten and X1 Gain.
2. Disconnect the BNC cable from the oscilloscope end of the ProBus extender cable. Reconnect
the end o f the cable to the precision 50 Ω termination.
3. Connect one end of a second BNC cable to the output of the Function Generator. Attach the
BNC to dual male banana plug adapter to the free end of the BNC cable. Insert the banana
plugs of the adapter into the input terminals of the Digital Multimeter (DMM).
4. Set the DMM to measure AC Volts.
5. Set the mode of the Function Generator to Sine Wave, the frequency to approximately 1 kHz,
and the output amplitude to read approximately 190 mV on the DMM.
