You can also edit and modify the output waveforms via the capacitive touch screen to quickly generate the waveforms you need.


(IV) Bus analyzer
The bus analyzer option (options S04~S13) can be used to trigger and decode packet level contents on commonly used serial bus (I2C, SPI, CAN, LIN, FlexRay, RS232, USB, Audio, MIL STD 1553, ARINC429) standards.
Support the full hardware trigger and decoding of multiple buses
The bus analyzer option provides a set of powerful serial bus trigger and analysis tools, supporting automatic trigger and analysis of I2C, SPI, CAN, LIN, FlexRay, RS232, USB, Audio, MIL STD 1553, ARINC4 29, etc. It also provides a test solution for serial buses, such as embedded, automotive, computer, and audio, etc. Besides, its all hardware decoding technology based on FPGA enhances the probability of capturing the occasional serial communication error code.





Support the display of multiple views
In addition to the traditional digital view, the bus analyzer option provides a higher level bus view display that allows you to identify various bus packet
types, such as packet start, address, data, and packet end; you can also view captured bus packets in the form of a time stamped event table.

4457H series oscilloscopes have a built in real-time spectrum analyzer function (option S22), with a maximum frequency range up to the oscilloscope
bandwidth, and real time analysis bandwidths of 10MHz, 20MHz, 40MHz, 80MHz, 160MHz and 320MHz. The use of superimposed FFT and digital fluorescence display technology makes the FFT refresh frequency greater than 400,000 times / sec, thus greatly improving the probability of capturing
narrow pulse or transient signals and enhancing the ability to view the occasion al event.

(VI) Digital voltmeter
The 4457H series oscilloscopes provide you with a 4 bit digital voltmeter and 8 bit frequency counter. The voltage and frequency measurement
functions are realized by multiplexing the oscilloscope channels, with the probes same as those of general-purpose oscilloscopes.

Multi window free settings, which features beautiful view and is conducive to observation
Users can freely hide, display, enlarge, shrink and split the open waveform windows according to their observation needs. You can operate multiple
window waveforms at the same time, and freely add or delete wa veforms in the window. Function windows can be dragged and docked around the main window, cascaded and tiled freely, or floated above other windows. After the instrument is connected to the extended display, the windows can be moved to the extended display , which is more convenient for waveform.

Free definition of shortcut bar fast and convenient
Users can customize the right shortcut bar according to their own habits, and set the frequently used function keys as shortcut keys in the function area, which helps users to quickly and directly open the corresponding function dialog box for operation.

Voice recognition control for smarter operation
Users can send commands to the oscilloscope through voice. By using the deep learning based method and the data intelligent processing technology, the oscilloscope can convert the user's oral commands into the oscilloscope's internal control commands to co mplete the user's desired operation, thus freeing up the hands and making the operation smarter and more convenient. In addition, the oscilloscope's voice recognition module also translates the user's operations into corresponding programmed control commands. Users can package multiple programmed control commands into executable code in multiple languages as needed, and can directly use these codes to write programmed control programs.
Standard 8U rack, with rich peripheral interfaces and powerful connectio n capability
The four USB3.0 master control ports and two USB2.0 master control ports at the front and rear allow easy transfer of screenshots, instrument settings and waveform data to a USB disk. They can also connect a USB keyboard or mouse to a USB host port for input, or connect a USB printer for screen image printing. The DP and VGA video output ports on the back of the instrument can export the displayed images to an external monitor or projector for teaching or demonstration of the oscilloscope.

The 8U standard rack and the 10/100/1000BASE-T Ethernet port at the back of the instrument can be easily connected to the network to realize remote programmed control of the network, which is convenient for function expansion and system establishment. With the oscilloscope same screen client, when controlling an oscilloscope over a network connection, you only need to enter the IP address and port number of the oscilloscope to provide a copy of the instrument's touch screen display area to the upper computer. You can transfer and save settings, waveforms, and screenshots directly from the upper computer, or control the oscilloscope in real time and use the mouse to operate in the copy display area, which is equivalent to operating the instrument's touch screen display area directly.
