Tektronix 5B42 60 MHz dual timebase plug-in

The Tektronix 5B42 is a 60 MHz dual timebase plug-in for the 5400 series oscilloscope family, delivering two independent timebases for simultaneous multi-signal display or expanded single-signal analysis. This module enables complex waveform analysis and timing relationship investigation across a wide sweep speed range—from 10 ns/div to 5 s/div on the main sweep—with dual display modes (CHOP and Alternate) optimized for different acquisition speeds.

– Technical Specifications

• Bandwidth: 60 MHz
• Main sweep: 10 ns/div to 5 s/div
• Uncalibrated sweep rate: 0.1 µs to approximately 12 seconds per centimeter
• Triggering bandwidth: 50 MHz
• Vertical sensitivity: 50 mV/div
• Inherent delay to start of delayed sweep: 2 V external signal
• Normal and fully triggerable delayed sweep capability
• Dual sweep operation in CHOP (recommended for slower displays) or Alternate (faster displays) mode

– Typical Applications

Complex waveform characterization, timing relationship analysis, and multi-signal observation in electronic circuit design and troubleshooting.

– Compatibility & Integration

Designed exclusively for Tektronix 5400 series oscilloscopes. Trigger signals from vertical plug-ins interface via rear connector pins 4A and 4B. Module incorporates Tek-made ICs, 155-0049-xx sweep control circuitry, and dual 155-0042-03 or 155-0028-00 Miller integrators. Serial numbers before B060000 use 10k ECL trigger gates; later units (B060000+) employ 155-0109-01 trigger circuits. Weight: approximately 2.00 lbs.
