- Page 2 In exercising its warranty, LeCroy, at its option, will either repair or replace any assembly returned within its warranty period to the Customer Service Department or an authorized service center. However, this will be done only if the product is determined by LeCroy’s examination to be defective due to workmanship or materials, and the defect is not caused by misuse, neglect, accident, abnormal conditions of operation, or damage resulting from attempted repair or modifications by a non-authorized service facility.

+INPUT and the other always on the –INPUT). The DXC100A Differential Probe Pair The DXC100A is a high performance matched passive differential probe pair designed for use with LeCroy differential amplifiers. The probe pair consists of two well-matched individual probes sharing a common compensation box allowing the attenuation factor on both probes to be simultaneously switched between 10X and 100X. -
Page 5: Dxc100A Probe Short Calibration Procedure
There are two situations where the DXC100A Probe Short Calibration Procedure is appropriate: When the DXC100A probe calibration status is unknown or it has been a long time since the probe has been calibrated. A small difference between the two probes can result in a significant CMRR loss, even though the error may be so small that it’s irrelevant to transient response. -
Page 6: Dxc100A Probe Full Calibration Procedure
If the probe pair has been repaired or is to be used on a DA1855A other than the one it was originally calibrated with, the probe pair should be calibrated using the following DXC100A Probe Full Calibration Procedure. The last step is to perform the DXC100A Probe Short Calibration Procedure as needed for high slew rate signals. -

CMRR (common mode rejection ratio) adjustments should be done with both probes connected to a BNC T (two female BNC and one male BNC connected together without any matching resistors). Note: With the DXC100A connected, let 20 minutes pass to allow the DA1855A to warm up before performing the calibration procedure. -

6. +Input X10 LF Compensation Note: Low frequency compensation of the DXC100A probe attached to the +Input is done by observing a small portion of the large amplitude step. With this magnification, the waveform shows considerable deviation from flat. What is important is that the front (1µs) and rear (about 10ms) of the waveform are at the same level. -

Operator's Manual 10. +Input X100 LF Compensation Note: Low frequency compensation of the DXC100A probe attached to the +Input is done by observing a small portion of a large amplitude step. For the 100X probe attenuation, the oscilloscope transient response plays an important part in determining the correct LF compensation adjustment. - Page 10 C8 (–X10 LF), R2 (-X10 HF1), R8 (-X10 HF2) or C18 (–X100 LF1), and R18 (-X100 HF1) as needed. This is the same as performing the DXC100A Probe Short Calibration Procedure.
