P6249 4 GHz 5X Active Probe Instruction Manual 45
The following steps instruct you to assemble the test setup that
includes the probe, as shown in Figure 14. The system and probe rise
time (ts+p) that you measure in step 12 is used to calculate the probe
rise time (tp) in step 13.
7. Disconnect the calibration generator remote head from the 1103
power supply input. Remove the SMA-BNC adapter from the
1103 power supply input.
8. Use the BNC locking ring to connect the probe to the 1103 power
supply channel 1 input. Disable the offset control on channel 1 of
the 1103 power supply.
9. Connect the probe tip adapter to the calibration step generator
remote head using the SMA female-female adapter. Insert the
probe tip into the probe tip adapter.

10.Press the AUTOSET button. Set the vertical to 10 mV/div and
horizontal to 100 ps/div. Turn averaging on.
11. Adjust the oscilloscope horizontal and vertical position controls
to display a signal similar to that shown in Figure 14.
