Tektronix 11A72 Manual page 9

General Information
This supplement to the User Reference manual for your mainframe describes the
features and operation of the Tektronix 11A72 Two-Channel Amplifier. The 11A72
Service Reference manual provides service information and test procedures for
the 11A72 Amplifier.
Functions common to all plug-in amplifiers, such as offset, sensitivity, input im-
pedance and coupling, are described in the User Reference for each mainframe.
This manual discusses the performance of systems that are configured using the
11A72 Amplifier.
Features DC to 1 GHz bandwidih (system bandwidth also depends on mainframe)
m Calibrated sensitivities from 10 mV to 1 V/div
= §0 0 input impedance
a High-resolution, calibrated DC offset (0.25 div/increment, coarse;
0.025 div/increment, fine)
= Coupling: AC, DC, or Off
m Display Polarity: normal or inverted
