2 Ch, 100 MHz Differential Amplifier and Comparator with Precision Voltage Source and Bandwidth Limit (10 MHz, 1 MHz, 100 MHz). Includes 2 each DXC100A Selectable /100 or /10 , Passive Differential Probe Pairs. The DA1855A 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 analysers, 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 DA1855A, including probe attenuation, amplifier gain and attenuator settings, is automatically displayed. The DA1855A has a bandwidth of 100 MHz, but any one of the three 3-pole bandwidth limit filters can be selected to reduce bandwidth to
20 MHz, 1 MHz or 100 kHz to limit noise above the frequency of interest. The DA1855A also features a built-in Precision Voltage Generator (PVG) that can be set to any voltage between +/-15.5 volts (+/-10 volts in Differential Offset) with up to 100 uV resolution. The PVG's 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.
