Aberrations Check

Use the following procedure to confirm that the P6205 probe
performs within its Aberrations specifications limits.

1. Set the oscilloscope controls as indicated in the table below.

Oscilloscope settings

Setting

Volts/division

50 mV

Time/division

500 ps

Trigger coupling

DC

Trigger source

Internal clock

2. Install one SMA-to-BNC adapter on an SD-24 sampling head

input channel and another adapter on the oscilloscope calibrator
output. Use the 10-inch coaxial cable to connect the oscilloscope
calibrator output to the SD-24 input channel. See Figure 4–7
below.
