350 MHz, ±300 V, 10X Attenuation, High-Temperature, Single-Ended Passive Oscilloscope Probe—The SP350X is a standard passive probe with fixed 10x attenuation for oscilloscopes that provide a 1 MΩ input impedance. It provides a wide temperature range from -55 °C to 155 °C and is ideal for performance in harsh environments where high relative humidity, damp heat, or condensation are common.
