Oscilloppoi - Preferences and Help

General

Audio Format - Input data format. You can choose '32-bit Float' or '32-bit Integer'.
Sampling Rate - Samples per second. if you choose 'Default', Sampling Rate is set by time base (refer to the list of Default Value).
Record Length/Queue - The record length defines the number of samples in a measurement. if you choose 'Default', Sampling Rate is set by time base (refer to the list of Default Value).

Default Value (except X-Y Mode)

Copy: Image Format - Choose image format: 'TIFF' or 'PDF'.

Control

User Interface - Select user interface 'Standard' or 'Slider'.

Standard: The controller type is circular slider.

Slider: The controller type is linear slider. 'V Scale' controller is linear slider too.

Scale: V Scale slider - Maximum value of 'V Scale' slider. This item is enabled only when you have selected 'Slider' interface.
Scale: V Position controller - Maximum value of 'V Position' controller.
Scale: H Position controller - Maximum value of 'H Position' controller.
Scale: Trigger Level controller - Maximum value of 'Trigger Level' controller.
Scale: Holdoff controller - Maximum value of 'Holdoff' controller.

Stop running after sweep has finished - When this option is checked and you press 'Stop' button, acquisition will not stop until current sweep finished.

Display

Grid Size - Select grid size: 40 - 120.
Number of Afterimages - Previous waveform is displayed like an afterimage. Set the number of afterimages.
Wave Line Width - Select waveform line width: 1 - 3.
Draw antialiased Waveforms - Set it to false to switch antialiasing off. Then, the load is reduced a little.

Color: Ch1 Wave Line - Set color of channel 1 waveform. X-Y mode waveform is the same color as it.
Color: Ch2 Wave Line - Set color of channel 2 waveform.
Color: Math Wave Line - Set color of 'Math' waveform.
Color: Frame Line - Set color of frame line.
Color: Center Line - Set color of center line.
Color: Grid Line - Set color of grid line.
Color: Trigger Line - Set color of trigger point and trigger level line.
Color: Information - Set color of information text.
Color: Background - Set color of background.

Source

Input: Ch1 - Choose the signal source: Input Device or 'Internal Signal Ch1'.
Input: Ch2 - Choose the signal source: Input Device or 'Internal Signal Ch2'.

Inputs from different devices are asynchronous.

Volume - Volume of the selected input device.

Internal Signal - Choose the waveform.

Sine Wave: Sine-1 or Sine-2.

Custom Wave: Triangle, Sawtooth, Square or Pulse.
- These signals are editable.

Output as sound - When this option is checked, Internal Signal is output as sound.
Volume - Volume of sound.
Device - Choose the output device.

Internal Signal Editor

Sine Wave:

Set parameters of the sine wave.

A - Amplitude.

f - Frequency (0.0 - 50,000.0Hz).

θ - Initial phase (-3600.0 - +3600.0degree).

Custom Wave:

Choose the name of the edited waveform.
'+' Add button - Add the new waveform.
'-' Remove button - Remove the selected waveform. This order can not be cancelled.

Amplitude - Amplitude of the waveform.
Width Unit - Time of 'w1'. The unit is millisecond.
1 / Term - Number of cycles per second.

The elements of the waveform:

The elements of the waveform are described by 'h' (height) and 'w' (width). The elements are separated by a comma.
h: range from -1.0 to +1.0
w: more than 0, relative value

(1) - The first point. If the height is zero, you don't have to write 'h0'.
(2) - The second point. When the height is the same as before, you don't have to write 'h'.
(3) - The third point. If the width is zero, you don't have to write 'w0'.
Total width is 1. As the width unit is '2ms', the term is 2ms.

(1) - The second point. The first point is omitted, because it is 'h0'.
(2) - The third point.
(3) - The fourth point.
Total width is 4. As the width unit is '0.5ms', the term is 2ms.
