The Keysight E2697A is a high-impedance adapter that connects oscilloscope probes to Keysight Infiniium oscilloscopes, enabling precise measurements across power supplies, inverters, and semiconductor devices. This adapter delivers 500 MHz bandwidth with switchable 1:1 and 10:1 attenuation, AC/DC coupling options, and input impedance of 1 MΩ ±1%. It accommodates dynamic ranges from ±0.8 V to ±80 V depending on attenuation setting and probe type, with maximum input voltage rated at ±100 V CAT I.
