levels. Record the oscilloscope calibrator voltage in the
Performance Test Record (see
Before proceeding to the next step, make sure that you have
recorded the oscilloscope calibrator voltage levels for each of
the threshold settings shown in
9 Use the 8-by-2 test connector to connect digital channels
D15-D8 to the output of the oscilloscope calibrator. Then
connect the D15-D8 ground lead to the ground side of the
8-by-2 connector.
10 Repeat this procedure (steps 7 and 8) for digital channels
D15-D8 to verify threshold accuracy and record the threshold
levels in the Performance Test Record (see
This test verifies the accuracy of the analog channel voltage
measurement for each channel (DC Vertical Gain Accuracy and
Dual Cursor Accuracy specifications). In this test, you will
measure the dc voltage output of an oscilloscope calibrator
using dual cursors on the oscilloscope, and compare the results
with the multimeter reading.
Test limits: ±2.0% of full scale ±1 LSB*
• On 300 MHz, 500 MHz, and 1 GHz models, full scale is defined
as 32 mV on the 2 mV/div range.
• On 100 MHz models full scale is defined as 16 mV on the
1 mV/div range.
• Full scale on all other ranges is defined as 8 divisions times
the V/div setting.
*1 LSB = 0.4% of full scale
