(1) Oscilloscope

12bit vertical resolution makes waveform details clearly visible and meets the demand for h igher vertical accuracy testing

12bit vertical resolution with 4096 levels of quantization allows difficult-to-insight signal anomalies to be clearly characterized.

Waveform capture rate of up to 700,000 waveforms/second helps to quickly detect and capture episodic events

A waveform capture rate of up to 700,000 waveforms/second and a sampling rate of 20 GSa/s greatly improve the probability of glitch and episodic events capture, allowing you to view more waveform details over a longer acquisition time.

Up to 1Gpts memory depth can maintain longer recording time at high sampling rates

On the strength of 1Gpts depth memory, the oscilloscope can maintain high sampling rate and waveform capture rate even in slow time base scale. The full hardware window extension allows you to locally zoom in on the details of the waveform, providing you with a synchronized display of the waveform's global and detailed information.

The 4457H series oscilloscopes come standard with segmented memory acquisition, which maintains high response speed and screen update rate even when the oscilloscope is operating in depth memory mode.

256 levels of grayscale and four waveform color displays provide an exceptional visual experience

The 4457H series oscilloscope uses digital fluorescent 3D display technology to indicate the probability of an event occurring by the brightn ess or warmth of the color, and provides 4 waveform colors (normal, reversion, color temperature, and spectrum), which enhances the ability to view episodic events.

Rich trigger functions and precise digital trigger help to accurately lock trigger events

4457H series oscilloscopes provide a rich set of trigger functions (including edge, edge transition, dual edge time, dual edge event, glitch, pulse width,
short pulse, timeout, code pattern, status, establish hold, window, area trigger (visible trigger) etc.) to help you quickly lock the event of interest in the
complex sampling information.

4457H series oscilloscopes use precise digital trigger technology to determinet he trigger point directly on the ADC acquisition samples, which can suppress the influence of interference signals and quickly lock the trigger event, thus laying the foundation for the oscilloscope to accurately display and analyze the signal. The trigger sensitivity of digital trigger is up to 0.1 division.

Visual trigger to provide intelligent waveform trigger positioning

4457H series oscilloscopes are further designed with visual area trigger function on the basis of various types of rich trigger types such as edge and edge transition. You only need to observe the signal of interest on the screen and draw an area around it. Then, the oscilloscope can quickly and easily
identify the desired trigger event by sweeping all captured waveforms and comparing them with the waveform area on the screen.

In addition, it also supports full memory automatic measurement in all acquisition modes, providing you with more accurate measurement results.

The 4457H oscilloscopes have powerful eye diagram and jitter analysis functions, which can quickly overlay and display eye diagrams for eye diagram parameter me asurements for all UIs captured each time. An in depth jitter analysis is also performed to show histograms, spectrograms, and trend charts of the time interval error (TIE), calculate the magnitude of each component of the jitter decomposition, and plot th e bathtub curves.

(II) Logic analyzer

The logic analyzer (option H01) provides 16 digital channels that are highly integrated with the oscilloscope user interface, thus simplifying operation and quickly solving problems in design and analysis of mixed analog digital signals.

High sampling rate of 2.5 GSa/s for finer timing resolution

The logic analyzer option can provide a 2.5GSa/s timing sampling rate and up to 400ps timing resolution for all digital cha nnels, thus reflecting the timing relationship of the signal under test more realistically.

Up to 160Mpts of memory depth supports long time tracking and recording

Up to 160Mpts depth memory enables the logic analyzer to maintain a high sampling rate while capturing long time records.

(3) Function generator

The function generator (option H02) features 2 output channels to help you simulate sensor signals or add noise to signals in your design, so as to perform margin test; it also allows you to transfer analog or digital signals captured by an oscilloscope to arbitrary waveform memory and copy the signals captured by the oscilloscope from the function generator.

Multiple predefined waveform outputs up to 50MHz

The function generator option provides up to 50MHz sine waveform outputs (also including square waveforms, ramp waveforms, pulses, DC, noise, arbitrary waveforms, S inX/X, exponential rise/fall, Gaussian, Lorentzian curve, half square curve, ECG and other waveforms), and supports the outputs of modulated waveforms, such as FM, AM, FSK, etc.

Arbitrary waveform output up to 64k points, and capacitive screen touch input for waveforms

The function generator option provides arbitrary waveform output function with 64k points recording length to copy waveforms from analog inputs, internal file save locations, USB disks, or external PCs from the w aveform generator. 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.

(5) Real-time spectrum analyzer

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.

(VII) Easy to use performance

New capacitive touch screen, with intimate design and excellent experience

The 15.6 inch capacitive touch screen supports single and multi touch, which can quickly realize the zoom and movement of waveforms. One touch
zeroing design simplifies operation by quickly zeroing horizontal, vertical and trigger positions. The numeric and bu s keypad significantly speeds up input. 4457 series supports mouse and key operation options along with touch operation.

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.
