The Tektronix 3A9 is a differential amplifier plug-in introduced in 1969 for 560-series scopes.
It provides a variable high-frequency cut-off from 100Hz to 1MHz.  It provides
a variable low-frequency cut-off from DC to 10kHz.  In the case where the frequency
response is set to go down to DC, the 3A9 provides a variable offset voltage.  The
3A9 provides differential high-impedance voltage inputs and an AC current probe input
for use with, for example, the [[P6021]] or [[P6019]].
The common mode rejection is 100,000:1.
