The Tektronix 7K11 is a cable TV pre-amplifier plug-in for 7000-series scopes and a cousin to the AM511. It is intended for use with a 7L12 or 7L14 set to a -30 dBm reference level (on its 50 Ω input). The reference level selected on the 7K11 is calibrated in dBmV. It has its own build in calibrator with 75 Ω output impedance. All RF connectors are BNC.
