The Tektronix 7B71 Delaying Time Base is a 200 MHz time base plug-in for 7000-series scopes. It was designed by Murlan Kaufman.

The 7B71 contains a delay function to control a "B" horizontal plug-in in four-slot mainframes, typically a model 7B70. It has no provision for X-Y mode.

The 7B70/7B71 were primarily intended for the 7704 mainframe. They were superseded by the 7B85/7B80 pair (400 MHz) in 1976, which increased the frequency range to 400 MHz and added digital read-out of the delay time.

Key Specifications

Excluded portions of sweep None in 7700-series, first 50 ns with magnifier
Trigger sensitivity 0.3 Div (int) or 75 mV (ext) up to 20 MHz, 1.5 Div or 375 mV from 20 MHz to 200 MHz
Trigger coupling DC, AC (>30 Hz), AC HF REJ (30 Hz to 50 kHz), AC LF REJ (>30 kHz)
Trigger input 1 MΩ // 20 pF, max. 500 V DC+peak AC
Jitter less than 1 ns at 150 MHz
Trigger Modes Peak-Peak Auto, Auto, Norm, Single Sweep
Variable time delay accuracy 1% (0.5 s/Div to 1 μs/Div)
Variable time delay multiplier Linearity within 0.2%
