P6205 Instruction Manual
Output Offset Check
Use the following procedure to confirm that the P6205 probe
performs within its Output Offset specification limits.
1. Set the oscilloscope controls as indicated in the table below.
Oscilloscope settings
Control Setting
Volts/division 2 mV
Trigger coupling DC
Time/division 1 ps
Trigger mode Auto
Enhanced accuracy On
2. Install an SMA-to-BNC adapter on one of the SD-24 sampling
head inputs. Use a 10-inch coaxial cable to connect the output of
the 1103 probe power supply to an SD-24 input channel.
3. Press SELECT CHANNEL on the sampling head to enable the
corresponding input channel.
4. Adjust the oscilloscope offset or position control to center the
trace at 0 V (or less than 1 mV).
Optional method: Use the oscilloscope measurement capability to
display the mean voltage of the free-running trace.
5. Insert the P6205 probe tip firmly into the 50
W
termination
adapter. (The BNC end remains unused.)
6. Connect the probe output to the 1103 probe power supply input.
7. Verify that the probe output offset (displacement of the
free-running trace) is less than
±
10 mV.
