Calibration for Hand-Held Browser Probe Heads
Calibration Setup
1168/9A Probes User's Guide
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.
NOTE
Before calibrating the probe, verify that the Infiniium oscilloscope has
been calibrated recently and that the calibration Δ temperature is within
±5 °C. If this is not the case, calibrate the oscilloscope before calibrating
the probe. This information is found in Infiniium Calibration dialog box.
The calibration procedure requires the following parts.
■
BNC (male) to SMA (male) adaptor
■
Deskew fixture
■
50Ω SMA terminator
1
As shown in
SMA (male) adaptor to the deskew fixture on the connector
closest to the yellow pincher.
2
Connect the 50Ω SMA terminator to the connector farthest
from the yellow pincher.
3
Connect the BNC side of the deskew fixture to the Aux Out
of the Infiniium oscilloscope.
4
Connect the probe to an oscilloscope channel.
5
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 yellow 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.
6
On the Infiniium oscilloscope in the Setup menu, select the
channel connected to the probe.
