The '''Tektronix Type 545''' is a 30 (33) MHz scope that takes [[letter-series and 1-series plug-ins]]. It has two timebases, which allows delayed triggering. | The '''Tektronix Type 545''' is a 30 (33) MHz scope that takes [[letter-series and 1-series plug-ins]].

Shorting the outputs of the vertical amplifier to ground can cause expensive damage by burning out the termination resistor network. | Shorting the outputs of the vertical amplifier to ground can cause expensive damage by burning out the termination resistor network. | ||
Starting at Type 545A serial number 29960, there is a 150 mA fuse, F1054, to prevent that failure. This change was made available for instruments already built, in Modification Kit 040-227. | Starting at Type 545A serial number 29960, there is a 150 mA fuse, F1054, to prevent that failure. | ||
