User Manual

This menu lets the user choose the acquisition method (normal, peak-detect,

averaging, and Eres (enhanced resolution), turn XY mode on and off, turn the

sequence feature on for capturing sequences of waveforms, set the size of the

waveform memory buffer, set the interpolation type (Sinx/x or linear), and set

the acquisition mode (fast or slow). Note: Only Normal Method screenshots can be

taken. If any other method is selected and a screenshot is taken the data will be

representative of Normal mode.

The save/recall menu lets you save waveforms and instrument settings to

internal memory or an external flash drive device connected to the front-panel

USB connector. You can save the instrument settings, a reference waveform, or

the waveform(s) displayed on the screen (either as a bitmap or in binary, CSV, or

MATLAB formats).

Turn on and off the optional function generator with 11 types of waveforms. The

menu's softkeys let you control frequency, period, amplitude, and DC offset.

Turn on and off the oscilloscope's measuring functions. A variety of waveform

parameters can be measured (e.g., amplitude, frequency/period, rise time, etc.).

An All Measure button lets you see all of these parameters at once. You can also

collect the statistics mean, minimum, maximum, standard deviation, and count

(number of samples) for selected parameters over time.

This menu lets you set the display type (dots: the sampled points, vectors: lines

are drawn between the dots), turn on the Color-

Grade display (a type of

histogram using color), persiste

nce (how long a particular trace stays on the

screen), the grid type and intensity, the trace intensity, and the transparency of

dialog boxes. It is also used to quickly turn the persistence on and off.

Perform utility tasks such as:

• Viewing informatio

n about the instrument (model, serial number,

firmware version, etc.)

• Self-calibration

• Turn the key click sound on and off

• Select language

• Set up pass/fail testing and USB/LAN settings

• Update the firmware or configuration from a flash drive

• Perform a self-test (screen, keyboard, or LED)

• Set the screen-saver time

• Add options and view which options are installed

Press the Decode button to open the decode menu (Decode is an optional

feature). The 2540C Series supports two 8-bit

serial buses for decoding.

Supported serial protocols include I

C, SPI, UART, CAN, and LIN.
