The Tektronix 7B70 is a 200 MHz time-base plug-in for 7000-series scopes. It has no delay function. For delayed-sweep applications, the 7B70 is operated in conjunction with the model 7B71 delaying timebase. The 7B70/7B71 were primarily intended for the 7704 mainframe.

The 7B71/7B70 were superseded by the 7B85/7B80 pair (400 MHz) in 1976.

X-Y operation

The 7B70 has a dedicated switch to put it in "amplifier mode" for X-Y operation. In this mode, the Trigger Source switch controls the signal source – internal from a vertical plug-in via the trigger path, or external — and the Trigger Coupling switch controls AC vs. DC coupling. In amplifier mode, gain can be varied using an uncalibrated potentiometer.
