The DXC100A is a high-performance, passive, matched, differential probe pair designed for use with the DA1800 series differential amplifiers. The probe pair consists of two highly matched individual probes that share a common compensation box to allow the attenuation factor on both probes to be simultaneously switched between 10x and 100x. When used with the DA1822 or DA1855A differential amplifier, the probe''s attenuation factor is automatically incorporated into the effective gain display, and the location of the decimal into the voltage generator display. Although primarily designed for use with the amplifiers, the DXC100A differential probe pair can be used with any oscilloscope or plug-in unit with an input impedance of 1 M(omh)/15-26 pF and one inch (25.4 mm) spacing between connectors. When used on a differential amplifier, the DXC100A compensation box allows for precise adjustment and matching of the transient response and optimization of the system Common Mode Rejection Ratio (CMRR).
