Offset (Preliminary)
NOTE. Do not at
tempt to adjust offset directly on an oscilloscope equipped with a TekProbe Interface. These o scilloscopes
utilize a closed loop compensation system for gain and offset which will interfere with the manual adjustment of the probe.
1. Connec
t the probe as shown above, with the probe tip connected to the DM pin of the BNC-to-probe tip adapter.
2. Set the
DMM to DC volts, 200 mV or 300 mV range.
3. Set the
probe to ÷ 5 attenuation, 5 MHz bandwidth, DC reject off.
4. Adjust
the ÷ 5 Offset adjustment for 0 mV ± 1 mV.
5. Change
the probe attenuation to ÷ 50.
6. Adjust
the ÷ 50 Offset adjustment for 0 mV ± 1 mV.
7. Keep th
e output cable set up for the next step.
