485 Tektronix Analog Oscilloscope


The 485 is a 350 MHz analog oscilloscope from Tektronix. Measure voltage or current signals over time in an electronic ciruit or component to display amplitude, frequency and rise times, etc. Applications include troubleshooting, production test, and design.

Additional Features:

  • Bandwidth: 350 MHz
  • Sensitivity to 5 mV/div
  • Selectable input impedance of 1 Mohm and 50-ohms
  • Also available are horizontal sweep rates to 1ns/division
  • Automatic deflection factor readout
  • 3 div/ns writing speeds

The Tektronix 485 is a dual-trace, portable analog oscilloscope with a maximum bandwidth of 350 MHz. The impedance of the inputs can be set individually to 50 Ω or 1 MΩ. The scope achieves its maximum bandwidth when the inputs are in 50 Ω mode.
