Specications of Model MR8740T

Trigger mark Trigger marks, which indicate the positions of trigger events, can be displayed.

Trigger timing Start

Alert function The alert function and trigger function other than the analog trigger setting are mutually

exclusive.

Available sampling rate: 100 kS/s or less

When the trigger conditions are satised

Displays and stores channel numbers and measured values, puts marks, and beeps

When the trigger conditions are not satised

Displays and stores channel numbers and measured values, puts marks, and turns off a

buzzer sound.

Auto-trigger level On/Off (for the trigger and alert functions)

Acquires the specied number of values and species the average value of them as the

reference of the window-out trigger.

Choose a number of samples from among 100, 200, 300, 400, and 500.

Sheet function Up to 16 sheets

A display format can be chosen for each sheet.

Zoomed display On/Off

Displays time-domain waveforms on the upper waveform screen and zoomed waveforms

on the lower screen.

Full-screen display Maximizes the waveform screen to full screen.

Waveform display Waveform color: Fixed colors (32 colors)

Interpolation: Line

Variable display: Always on

Vernier: Amplitudes of inputted waveforms can be adjusted. (Adjustable

range: 50% to 200% of input)

Grid: Off/On

Logic width: Wide, standard, narrow

Inverted waveform: Polarity-reversed waveforms can be displayed.

(Not available for Model 8967 Temp Unit, Model 8970 Freq Unit, or

Model 8973 Logic Unit)

Zoom in/out Waveforms can be displayed at a preferred magnication.

Waveform scrolling The operator can scroll through waveforms horizontally by dragging the display.

Scrolling through waveforms backward is available during a measurement.

Rolling display Latest data is always displayed following the measurement.

The drawing starting position can be chosen between the left edge and right edge.

(The rolling display is not available when the overlay setting is used.)

Overlaying

waveforms

Overlaying setting can be selected from off, automatic, manual.

(The rolling display is not available when the overlay setting is used.)

Cursor

Trace cursor: Up to 8 cursors can be displayed.

(Displays potential, time from trigger, time lag between cursors, and

potential difference between cursors.)

Horizontal cursor: Up to 8 cursors can be displayed.

(Displays potential and potential difference between cursors.)

Gauge: Up to 8 cursors can be displayed.

Section designation: Section cursor 1 or section cursor 2

(Species calculation range, save range, and search area.)

Jump: Jumps to the position specied by clicking the screen.

Event mark Event marks can be put during measurement (up to 10,000 marks)

by clicking the start icon or inputting an external signal.
