The Tektronix 5440 (5403/D40) s a 60 MHz 5000-series oscilloscope that uses three 5400/5000-series plug-ins.

All 5000-series plug-ins work in the 5440. When 5400 series (non-N) plug-ins are used, e.g., the 5A48, the 5440 provides on-screen readout, unless the 5440 has Option 1 (no CRT readout). 5000-series plug-ins whose model name ends in an "N" will work in a 5440, but without readout, i.e., the signal trace will work normally.


please add

CRT accelerating voltage is 15 kV.
