Differential amplifiers are intended to act as signal conditioning preamplifiers for oscilloscopes and network and spectrum analyzers, providing differential measurement capability to instruments having only a single-ended input. The "-PR2" version of each amplifier is a dual channel unit. The DXC series differential input cables are matched to the characteristics of the amplifier. ÷100 2.5KV Passive High Voltage Probe Pair for DA18xxA series. Requires DA101 for full performance Bandwidth: 250MHz
