Calibration for Hand-held Browser Probe Heads

Calibration of the hand-held browser probe heads consists of a vertical calibration

and a skew calibration. The vertical calibration should be performed before the

skew calibration. Both calibrations should be performed for best probe

measurement performance.

Before calibrating the probe, verify that the Infiniium oscilloscope has been calibrated recently

NOTE

and that the calibration

oscilloscope before calibrating the probe. This information is found in the Infiniium Calibration

dialog box.

The calibration procedure requires the following parts.

• BNC (male) to SMA (male) adapter

• Deskew fixture

• 50 Ω SMA terminator

For the following procedure, refer to

temperature is within ±5 °C. If this is not the case, calibrate the

Connect BNC (male) to SMA (male) adapter to the deskew fixture on the

connector closest to the pincher.

Connect the 50 Ω SMA terminator to the connector farthest from the pincher.

Connect the BNC side of the deskew fixture to the Aux Out of the Infiniium

oscilloscope.

Connect the probe to an oscilloscope channel.

Place the positive resistor tip of the browser on the center conductor of the

deskew fixture between the green line and front end of the pincher. The

negative resistor tip or ground pin of the browser must be on either of the two

outside conductors (ground) of the deskew fixture.

On the Infiniium oscilloscope in the Setup menu, select the channel connected

to the probe.

In the Channel Setup dialog box select the Probe Config... button.

In the Probe Configuration dialog box select the Calibrate Probe... button.

Select the Start Atten/Offset Calibration... button and follow the on-screen

instructions for the vertical calibration procedure.

Once the vertical calibration has successfully completed, select the Calibrated

Skew... button.

Select the Start Skew Calibration... button and follow the on-screen

instructions for the skew calibration.
