Tektronix 2445A
Oscilloscope 150MHz 4Ch
Description
The Tektronix 2445A is a Oscilloscopes with 4 Channels and a bandwidth of 150 MHz. The 2445A Oscilloscope has powerful features and portable versatility. Four independent channels, 150MHz bandwidth at probe tip, 250MHz minimum triggering bandwidth, 1ns/div sweep rate, and waveform cursors will provide flexibility. The other features are CRT readout, Delayed Sweep, Delta V, Delta T, 1/Delta T, Tracking and Independent modes, selectable 1 Mohm/50 ohms inputs, and an automatic front-panel DC balance adjust.
