En Introduction Thank you for purchasing the Multifunctional Utility Kit for the Nu:Tekt NTS-2 Os- cilloscope Kit. To help you get the most out of your purchase, please read this manual carefully.

Main features of this unit This product is an assembly kit that you can use to build a digital oscilloscope. Aside from letting you view audio output waveforms and CV signals, this oscilloscope func- tions as a spectrum analyzer, offers a built-in tuner for tuning analog synthesizers, and lets you output LFO, CV and other signals with its function generator.

Computer

Use the included USB cable to connect this unit to the USB port on your computer or to a commercially available USB standards-compliant AC adapter (at least 5 V DC 550 mA).

Make sure to use the included USB cable. Use a cable thats no more than 3 m long when connecting your peripherals to this

unit. Make sure to use an AC adapter thats compliant with USB 2.0 standards. Note that

some standards-compliant USB AC adapters might not operate correctly.

Turning the power on/off Long-press the power button to turn on the unit. Long-press the power button again to turn the unit off.

Auto power-off function The Nu:Tekt NTS-2 features an auto power-off function that automatically turns the unit off after one hour has elapsed without the knob, switches, buttons or other controls being operated. The auto power-off function is enabled by factory default. Auto power-off can be disabled using the steps below. 1. Use the mode button to enter global mode. 2. Press button 4 (SETTINGS: Power) a number of times to select Auto Power

Off(USB) or Auto Power Off(Battery). 3. Turn the value knob to change the value to infinite.

Four operating modes

Oscilloscope mode (SCOPE) You can view the waveforms from up to four input sources. The functions below are assigned to buttons 14.

1: DISPLAY: Switches between input signals. 2: VERTICAL: Sets the display range for the vertical screen direction (voltage). 3: HORIZONTAL: Sets the display range for the horizontal screen direction (time). 4: TRIGGER: Sets which change in input signal causes the display to update.

Function generator mode (WAVE) In this mode, signal is output from the OUTPUT 1 and 2 jacks. These outputs can be used even while an input signal is being received. You can use the START/STOP button to turn the waveform output on/off, continuously output the waveform by holding down the button, or output only one cycle of the waveform (one-shot) by just pressing the button. The functions below are assigned to buttons 14.

1: CATEGORY: Selects the waveform for OUTPUT 2, sets the level and so forth. 2: EDIT: Configures the detailed settings for the OUTPUT 2 waveform. 3: CATEGORY: Selects the waveform for OUTPUT 1, sets the level and so forth. 4: EDIT: Configures the detailed settings for the OUTPUT 1 waveform.

Spectrum analyzer mode (FFT) This mode lets you observe the frequency characteristics of the input signal, by using a spectrum analyzer that employs an FFT (fast Fourier transform) algorithm. The func- tions below are assigned to buttons 14.

1: INPUT: Switches between input signals. 2: VERTICAL: Sets the display range for the vertical screen direction (voltage). 3: HORIZONTAL: Sets the display range for the horizontal screen direction (time). 4: TRIGGER: Sets which change in input signal causes the display to update. Nor- mally, this is set to AUTO.

Tuner mode (TUNER) This mode measures the pitch of the input signal from the oscillator of an analog syn- thesizer or other source. You can select between a horizontal meter and a needle-type (VU) meter view. The functions below are assigned to buttons 14.

1: DISPLAY: Selects the tuner display mode. 2: INPUT: Switches between input signals to measure. 3: CALIB: Adjusts the pitch lower or higher than the reference pitch of A=440 Hz. You can adjust the pitch within a range of 410480 Hz. 4: SCOPE: Switches the oscilloscope display on/off.

Basic operations 1. Each time you press buttons 14, the parameter assigned to the button in question

changes one at a time and is shown in the popup screen in the display. 2. Once the desired parameter is shown, turn the value knob to edit the value. 3. Measurement starts/stops with each press of the START/STOP button.

This product is a multi-tool intended for use with musical instruments. Do not use this product for anything under than its intended purpose, such as for calibrating measurement devices and so on.

Oscilloscope mode (SCOPE) Oscilloscope mode lets you monitor the input signals coming from the four input sourc- es (INPUT 1, 2 L/R). Use VERTICAL to set the voltage range for the vertical screen direction. For example, a 5V setting will display a 5 V voltage for each mark on the vertical axis. Use HORIZONTAL to set the time scale in the horizontal screen direction. Use the DISPLAY setting to select the inputs shown on the oscilloscope, display multiple inputs separately or stacked on top of each other, or to display two inputs as an image for comparing two different signals. To compare two signals with each other, set the vertical and horizontal directions to the same setting. Use TRIGGER to set the timing at which the scope measures the signal input.

Spectrum analyzer mode (FFT) Spectrum analyzer mode uses an FFT (fast Fourier transform) function that lets you monitor the reference waveform along with a frequency spectrogram of the input signal. This is useful for seeing where the effects of a filter or the changes you make to a waveform appear in the frequency bands.

Tuner mode (TUNER) Use the tuner to tune one of the four input signals. Both a horizontal meter and a nee- dle-type (VU) meter view are available. DISP: NEEDLE DISP: METER

You can set the reference pitch to a value other than 440 Hz (this is also called concert pitch, meaning a range from middle C to the A below that). With this function, you can tune multiple oscillators at the same time by transmitting the same pitch (note) and adjusting the pitch while monitoring.
