The Tektronix 11A52 is a two-channel amplifier plug-in module for Tektronix 11000 and DSA600 series oscilloscopes, delivering DC to 600 MHz bandwidth with independent channel control. It enables high-speed signal acquisition and analysis with calibrated vertical sensitivities from 1 mV/division to 10 V/division, 50 Ω input impedance, and 580 ps rise time on 1 GHz mainframes. The module includes selectable 100 MHz and 20 MHz bandwidth limit filters, AC/DC/OFF coupling modes, and calibrated DC offset with ranges up to ±100 V depending on sensitivity setting. Fast overdrive recovery and 5 V RMS input overload protection ensure reliable operation in demanding measurement environments.
