Page 9: Low-Frequency Compensation
Low-Frequency Compensation Low-Frequency Compensation The N2871A, N2872A, N2873A, N2875A, and N2894A can be adjusted for low fre- quency (LF) compensation. The N2870A, N2874A, and N2876A cannot be adjusted. The probe should be adjusted for LF com- pensation when it is connected to an oscil- loscope input for the first time. -
