The Tektronix 7B52 is a 100 MHz dual time base plug-in for 7000-series scopes. It was designed for the 7503 mainframe but is compatible with the entire series.

The 7B52 is similar to the 7B53A which is much more commonly found (main difference is the separate mode switch which is integrated into the time/Div switch in the 7B53A).

Key Specifications

Sweep rates 50 ns/Div to 5 s/Div in 1—2—5 sequence
Deflection 10 mV/Div, 100 mV/Div or 1 V/Div, up to 2 MHz
Sensitivity 0.3 Div or 150 mV up to 10 MHz, 1.5 Div or 750 mV up to 100 MHz
Coupling DC, AC (> 30 Hz), AC LF REJ (> 30 kHz), AC HF REJ (30 Hz — 50 kHz)
Input impedance 1 MΩ // 20 pF
Jitter < 1 ns at 75 MHz
Features
  • Dual delayed timebase
  • External trigger inputs for main and delayed
  • Display modes: Main, Intensified, Delayed, Mixed

Operation

The 7B52 supports X−Y mode through the "Amplifier" setting of the Time/Div switch. The Trigger Source determines whether the X signal is taken from a verical plug-in via the internal trigger path or from the external trigger input.

A switch accessible through the side panel allows the user to select the delayed timebase trigger input - either the main trigger signal on pins A20/B20, or an auxiliary trigger signal supplied via pins A21/B21. The 7403N mainframe supplies the Left Vertical trigger signal on these pins. It is not known if other mainframes supply this signal, and the 7B52 is the only plug-in known to access this signal. (Any information welcome!)
