• Normal mode displays a waveform when the trigger conditions are met, otherwise the oscilloscope does not trigger and the display is not updated. • Auto mode is the same as Normal mode, except it forces the oscilloscope to trigger if the trigger conditions are not met. -
Page 9: Horizontal Sensitivity Setting
20mV/div to 10V/div. In the right side of the menu, coupling option can be adjusted as AC or DC. OFF position should be selected to avoid appearing signal on the screen. In a similar way, the settings can be made via the menu numbered (15) for the Channel-2. Figure 5. -
Page 10: Cursor Function
Figure 6. Horizontal sensitivity setting 3.5. Cursor Function To perform measurement on the observed signal, 'Cursor' menu is used. 'Cursor' menu could be activated by selecting the button which is seen as (22) in the Figure 3b (Menu 2). To switch to Menu 2, the buttons providing switching among the menus are used (in the Figure 3a, (10) and (19) buttons). -
Page 11: Auto Measurement
3.6. Auto Measurement Some values related on signal are measured automatically. The measured values are gathered into two categories; voltage and time. These values are seen in the area (1). In the Menu 2, the ‘Measure’ menu, which is accessible by selecting the button (24), can be used to select various combinations. These options are shown in the Table 2. -

Figure 8. Auto measurement menu 3.7. Operating Mode The triggering requirement of the oscilloscope defined in the operating mode. These characterizations are performed via the buttons numbered (20) and (21) from the Menu 2 (Figure 3b). • Running: Determines wave form even if it cannot define triggering requirement in this operating mode. -

3.8. XY Operating Mode The XY mode plots one channel against another on the screen. The XY mode is useful to show the phase relationship between periodic signals and for plotting the I-V (current-voltage) character of electronic components. Electronic components can characterized by applying a current-limited AC sine wave... -

Page 16: Signal Generator
4. Signal Generator 64-point data signals are produced by 12-bit 1-Msps DAC on the oscilloscope. In the main menu, when users select ‘Signal Generator’ (Figure 1) button, the menu below displays (Figure 13). In the menu, there are slidebars to arranges the signal's offset voltage, amplitude and frequency. These slidebars provide coarse adjustments. -
Page 17: Color Setting
5. Color Setting The optimum color combination was chosen for the oscilloscope design. But it is also possible to personalize these colors. When the ‘Set Colors’ button on the Settings menu is clicked, we see the following display (Figure 22). In order to change predefined colors on the left side of display click on it. The new color is determined by clicking on the color scale on the right side. -

6. USB Disk When the ‘USB Disk’ button from the main menu is selected, oscilloscope connects to computer as a USB disc. In computer's ‘Devices and drivers’ section, device is listed (Figure 16). The internal memory access would be available via USB Disk. Thus, the saved files can be transferred to PC platform. To end up the USB Disc connection and switch backward to the main menu, the ‘DISCONNECT’... -

Page 20: Adc Calibration
9. ADC Calibration For a better signal sampling, a correct ADC calibration is necessary. Calibration process starts by selecting the ‘ADC Calibration’ button from the main menu. Probes connected to both channels are connected to GND terminal (Figure 21). If the calibration parameters are stable within the specified limits touch anywhere on the display to complete the calibration and return to settings menu.
