Tektronix Type 535 10*/15 MHz oscilloscope

The Tektronix Type 535 is a dual-trace oscilloscope engineered for waveform analysis and precision electronic testing across research, manufacturing, and service environments. This 15 MHz instrument delivers real-time signal observation via a 6.5 cm × 8.8 cm CRT display, with independent vertical channels capable of simultaneous measurement and analysis. Vertical deflection spans 50 mV/div to 10 V/div with ±3% accuracy, while horizontal sweep ranges from 0.2 µs/div to 5 s/div, also within ±3% accuracy. The 23 nanosecond risetime and 1 MΩ input impedance (shunted by ~17 pF) support demanding measurement tasks. Multiple triggering sources—CH1, CH2, combined CH1 & CH2 (chop or alternate), external, and line—with selectable Auto, Normal, or Single Sweep modes provide flexible signal capture control. Trigger sensitivity reaches 0.5 div for Auto mode and 1 div for Normal/Single Sweep internally; external triggering requires 50 mV. The 10× sweep magnification option enables detailed waveform inspection. AC, DC, and Ground input coupling options accommodate diverse signal types. Standard BNC connectors interface with industry-compatible passive and active probes, while a dedicated probe compensator output ensures measurement accuracy. Built into a rugged metal chassis with carrying handle, the instrument operates from 105–125 V or 210–250 V AC mains (50/60 Hz) at approximately 200 VA. Dimensions are 13.5 inches (H) × 12.4 inches (W) × 19.5 inches (D); weight approximately 30–35 lbs.
