Function

F None

Soft keys. Their function is shown at the right side of the screen. The

button 27 (MENU ON/OFF) can be used to turn the menu on and off.

1 Print

When pressed, the displayed waveforms are saved into a file in external

memory (e.g., a USB thumb drive). You can choose to either save the

waveforms as either a CSV (comma-separated values) or four types of

bitmap images (8 bit BMP, 24 bit BMP, GIF, or PNG).

CH1

Input male BNC terminal for channel 1's vertical amplifier.

CH2

Input male BNC terminal for channel 2's vertical amplifier.

EXT TRIG/MOD

OUT

External trigger input for scope operation or, if the function generator is

supplying a modulated waveform, this terminal outputs the modulation

waveform.

GEN OUT

Output terminal for the function generator.

VOLTS/DIV

Adjusts the vertical sensitivity (gain) of channel 1.

VOLTS/DIV

Adjusts the vertical sensitivity (gain) of channel 2.

8 TIME/DIV

Adjusts the horizontal time base in seconds per division (or SI

multiples).

ON/OFF

Turns the output of the function generator on and off.

10 CH1

Accesses channel 1's menu and turns channel 1 on. Pressed again, it

turns channel 1 off.

REF

Turns the reference waveform menu on and off.

12 MATH

Turns the math menu on and off. This menu allows you to perform

mathematical functions with two waveforms: add, subtract, or multiply. It

also lets you calculate the FFT (fast Fourier transform) of channel 1 or 2.

13 CH2

Accesses channel 2's menu and turns channel 2 on. Pressed again, it

turns channel 2 off.

Access the horizontal menu.

AMPL

Adjust the amplitude of the function generator.

FREQ

Adjust the frequency of the function generator.

POSITION

Channel 1's vertical position on the screen.

POSITION

Channel 2's vertical position on the screen.

POSITION

Horizontal position of the trace(s) on the screen.

Function generator menu.

21 ◄ ►

When the knob 28 is used for some adjustments, these two buttons are

used to select which digit is to be adjusted. Also used when displaying

help screens.

22 AUTO

Initiates an automated measurement sequence (this is called the

Autoset function). This will automatically set the controls to display the

signals on channel 1 or channel 2 or both.

23 FORCE

Immediately forces the oscilloscope to trigger. This is useful when the

trigger mode is set to NORMAL in the absence of a trigger signal, as

you can see where the trace is on the screen.
