⑤ RAGU^® V 1.0 Operation Screen Explanation

2023.05.15

This article explains the operation screens of the RAGU^® software.

●Main GUI
The main screen has the following 4 areas, indicated by the red rectangles (01) to (04) in the screen image.

(01) ON Switch: Enables access to RAGU
(02) DUT Control Settings: Input control signals of DUT (motor driver LSI)
(03) Graph/Plot Area: Graphs and measured values
(04) Oscilloscope Settings: Performs settings for the oscilloscope

Below are described the settings for each of the 3 areas other than the ON switch.

●DUT Control Settings
Aside from the switch ON display, the DUT control area has 4 settings: “Level”, “Computation”, “Clock output”, and “Pin voltage levels”. The table below shows settings for each of these.

(01) Operating Mode		Switch that enables access to RAGU
(02) Levels	(a) Voltage level	・Values can be changed by either the sliders or text boxes. ・To move from one text box to another, use the Enter key. ・The sliders can be configured using the　MAX, STEP and MIN text boxes.
(02) Levels	(b) Frequency level	・Values can be changed by either the sliders or text boxes. ・The CLK slider can be configured using the MAX, STEP and MIN text boxes.
(03) Computation		・The calculated Io (output current) value is displayed.
(04) CLK Output		・Use the Start button to enable or disable the clock output. ・Continuous mode: The clock output continues until the Stop button is clicked. ・Manual mode: The specified number of clock cycles are generated.
(05) Pin voltage level		・Set the voltage levels of the selected pins.

●Graph/Plot Area and Oscilloscope Settings
The graph/plot area and the oscilloscope settings area are related, and so these are explained together. Broadly stated, there are settings for the “graph/plot area”, for the “channel settings”, and for “sampling evaluation”. For details of each of these, please refer to the table below the graphic image.

(01) Graph/plot area	(a) Time-delta measurement	・Use the right double click to turn ON/OFF, use the right single click to move the blue cursor. ・Time is measured between the red (left click) and blue (right click) cursors.
	(b) Time-value display	・Use the left double click to turn ON/OFF, use the left single click to move the cursor.
	(C) Horizontal scroll	・Use the left and right arrow buttons to scroll through the waveform.
(02) Channel settings	(a) On/Off	・Show/hide the specified channel.
	(b) Source	・Select measurement source (output voltage/output current/ICC (circuit current)).
	(c) Output	・Channel select (A/B).
	(d) Value/Div	・Display the current value (I/Div) or voltage level (V/Div) of each channel.
	(e) Range	・Change the Value/Div settings.
	(f) Setup	・Open the Channel Settings window.
	(g) Sec/Div	・Control the TIME/Div setting of the display (in seconds).
	(h) Sampling rate	・Control the sampling frequency of the waveform scope.
(03) Sampling evaluation	(a) Trigger	・Turn on/off triggering.
	(b) Channel	・Select channel.
	(c) Current	・Change triggering current level.
	(d) Voltage	・Change triggering voltage level.
	(e) Run/Stop	・Enable/disable sampling. ・Continuously read the 4 channels and plot them in chart. ・Only the currently available data in the RAM (8k samples) will be displayed at any time.
	(f) Save	・Export graph as image (jpg.).
Note: Only one slider is active at any time. The active slider will depend on the input type (voltage/current) of the currently selected channel.

●Dynamic Window (Refer to “④ Explanation of RAG U V1.0 Functions”)
The dynamic window is a “DUT control setting”. It is selected by choosing “View → Dynamic Window Menu Item”.

・The Dynamic Settings window allows the user to preprogram a sequence of configurations to the RAGU main board (RAGU-main1-EVK-001).
・The Run Cycle determines the repeat count for the whole sequence.
・The Repeat Delay sets the time between each cycle.
・Click “Start” to begin the specified sequence.

●Temperature Monitor (Refer to “④ Explanation of RAG U V1.0 Functions”)
The Temperature Monitor is also a “DUT control setting”. It is selected by choosing “View → Tj Monitor Menu Item”.

・The Temperature Monitor window allows the user to preprogram a sequence of configurations in order to monitor the temperature at each setting.
・At the end of the sequence, the logged temperature data is plotted into a Microsoft Excel Spreadsheet.
・Click “Start” to begin temperature monitoring.
・Click “Save Chart” to plot the existing temperature log in a spreadsheet.

●Calibrate
The calibrate function is found under the Help Menu. Ensure that all oscilloscope functions are turned off before calibrating the RAGU main board (RAGU-main1-EVK-001) or the RAGU option board (RAGU-op1-EVK-001). Calibrating the boards while using the oscilloscope may result in an incorrect calibration.
