## Description

Size:2 Channel




























This is a stand-alone, high-performance 100 MHz differential amplifier. It is intended to act as a signal conditioning preamplifier for oscilloscopes, digitizers and spectrum analyzers, providing differential measurement capability to instruments having only a single-ended input. Amplifier gain can be set to 1 or 10. A built-in input attenuator can be separately set to attenuate signals by a factor of 10, providing gains of 10, 1, or 0.1 and common mode dynamic range of +/-15.5 V (÷1) or +/-155 V (÷10). Optional probes increase the maximum input signal and common mode ranges in proportion to their attenuation ratio but do not exceed their maximum input voltage rating. Effective gain of the amplifier, including probe attenuation, amplifier gain and attenuator settings, is automatically displayed. The amplifier output is carefully limited to +/-500 mV, so that the oscilloscope is not overdriven by large inputs. This allows many oscilloscopes to directly measure the settling of D/A converters with 14-bit (60 ppm) precision, better than any other differential comparator. The amplifier features a built-in precision voltage generator (PVG) that can be set to any voltage between +/-15.5 V (+/-10 V in differential offset) with up to 100 microvolt resolution. The PVGs output can be selected as an input to the inverting (-) input of the amplifier for operation as a differential comparator or applied internally as a true differential offset voltage. The PVG is also available for external use through a rear panel connector. The amplifier operates from 90 to 250 VAC line without line switching. High-performance differential probes such as the DXC100 ÷10/÷100 high CMRR probes are recommended. Selectable bandwidth limiting. Two gain control modes when connected to a LeCroy oscilloscope. Comparator and true differential offset modes. Industry-leading overdrive recovery. Amplifier comes with fast over drive recovery, calibrated offset, and selectable LP filters.
