Performance Verification
Test 1. DC Input Resistance
Refer to the list of required equipment in Table 6 on page 60.
NOTE Allow the probe to warm up for at least 20 minutes.
Procedure
1 Snap the socketed tip onto the probe. The socketed tip is the easiest to use in
this test.
2 Connect the probe to one of the oscilloscope’s channel inputs. This ensures
that the probe is powered.
3 Turn on the oscilloscope.
4 Using the digital multimeter, measure the DC input resistance between leads A
and B . This is the differential resistance and should measure 200 k Ω ± 2%.
5 Measure the single-ended input resistance between lead A and the ground
lead. The resistance should measure 100 k Ω ± 2%.
6 Measure the single-ended input resistance between lead B and the ground
lead. The resistance should measure 100 k
Ω
± 2%.
7 Enter the measured values in Table 7 on page 73.
