2 front USB2.0 HOST ports for insertion of mouse, keyboard and USB storage devices.
2.2.3 Logic analyzer extended ports
Fig. 2.6 Logic Analyzer Ports
The logic analyzer extended ports are used for signal input of 16 digital channels, which will be opened when the
4456-H01 option is selected.
2.2.4 Waveform generator extended ports
Fig. 2.7 Waveform Generator Ports
The waveform generator extended ports are used for the waveform output of 1 channel, with 50Ω output
impedance. The extended ports will be opened when the 4456-H02 option is selected.
2.2.5 1 kHz Calibration Signal
Fig. 2.8 1kHz Calibration Signal
The output probe square wave calibration signal, with about 1 kHz frequency and 3 Vpp amplitude, which is
mainly used for probe calibration and keeping flat amplitude-frequency characteristics of the oscilloscope by
adjusting the adjustable capacitance of the probe.
2.2.6 Screen Display Area
The Screen Display Area is an interaction window between the oscilloscope and the user, and information
including waveform and measurement result will be provided through it. The Screen Display Area of the
oscilloscope is mainly composed of the Horizontal Status Display Area, Running Status Display Area, Waveform
Display Area, Measurement Result Display Area, Vertical Status Display Area, Trigger Status Display Area,
System Time Display Area, Level1 Menu, Level2 Menu andLevel3 Menu.
