Tektronix 7B53A is a 100 MHz dual time base plug-in designed for use with the 7000-series oscilloscopes. It provides two independent sweep generators—main and delayed—which allow for advanced triggering and time-domain analysis, such as zooming in on specific waveform segments.
Key features include:
Sweep rates from 50 ns/div to 5 s/div (down to 5 ns/div with ×10 magnification)
Display modes: Main, Delayed, Mixed, and Intensified
Triggering options: Internal, External, Line, and TV Sync (with Option 5)
Input impedance: 1 MΩ // 20 pF
Coupling modes: DC, AC, LF Reject, HF Reject
