Description
The TEKTRONIX 2445B Oscilloscope is portable 200-MHz bandwidth instrument having four-channel vertical deflection system. Channel 1 and Channel 2 provide calibrated deflection factors from 2 mV per division to 5 V per division. For each of these channels, input impedance is selectable between two values: either 1 MΩ in parallel with 15 pF, or 50-Ω internal termination. Input-signal coupling with 1-Mrl impedance can be selected as either AC or DC. Channel 3 and Channel 4 have deflection factors of either 0.1 V or 0.5 V per division. Each of these channels has an input impedance of 1 MΩ in parallel with 15 pF, with DC input-signal coupling.
The trigger system works automatically for most signals. They operate in various modes, from any channel, with couplings for a wide range of signals. The 2445B trigger system gives stable displays from dc to 250 MHz. The 2455B trigger system gives stable displays from de to 500 MHz.
