TF-DSQ
PROBE DESKEW AND CALIBRATION
272 1-800-5-LeCroy
PROBES AND
PROBE ACCESSORIES
The TF-DSQ fixture facilitates calibration of timing measurements in single-ended and
differential probes—a unique concern in high-speed measurements. By requiring only
one connection of a probe to the fixture and one button press, the TF-DSQ ensures
probe calibration results that are valid for the duration that the probe is connected to
the circuit. An extremely fast edge with 75 ps risetime combines with probe gain and
offset calibration capabilities for added accuracy.
Features:
• Deskews to ±20 ps typical accuracy
• Differential and single-ended drive
• 75 ps edge for precise deskewing
• Calibrates gain, offset and skew at the same probing point
• Accounts for risetime variations
• Accounts for common-mode voltage variations
• DC gain calibration accounts for probe loading effects
• Integrated operation with scope for fully automatic calibration
