FNIRSI 1014D Oscilloscope

1. Product Overview

The FNIRSI 1014D is a versatile 2-in-1 digital oscilloscope and DDS signal generator designed for a wide range of electronic testing and measurement applications. It features a real-time sampling rate of up to 1GSa/s and an analog bandwidth of 100MHz x 2, making it suitable for both periodic analog and aperiodic digital signals.

Key Features:

• High Performance Oscilloscope: Real-time sampling rate up to 1GSa/s, 100MHz x 2 analog bandwidth, supporting single/normal/automatic trigger modes.
• Integrated DDS Function Signal Generator: Outputs 2.5VPP, signal frequency steps of 1Hz, supports 14 types of function signals and customizable chopping signals with storage for up to 1000 customized signals.
• Easy Measurement: Cursor measurement function for direct peak-to-peak value and frequency readings without manual calculation.
• Clear Display: Equipped with a 7-inch 800x480 resolution high-definition LCD screen for improved readability.
• User-Friendly Operation: High-efficiency one-button AUTO function with adaptive 25%, 50%, 75% trigger for quick waveform display.
• Advanced Analysis: Lissajous Graphic Display for comparing amplitude, frequency, and phase of two signals, and FFT viewing for harmonic content estimation.

3. Initial Setup

Follow these steps to set up your FNIRSI 1014D Oscilloscope for the first time:

1. Power Connection: Connect the provided power adapter to the DC input port on the rear of the oscilloscope and plug it into a suitable power outlet.
2. Probe Connection: Connect the oscilloscope probes to the BNC input connectors (CH1, CH2) on the front panel. Ensure a secure connection by twisting the BNC connector until it locks.
3. Probe Calibration: For accurate measurements, it is recommended to calibrate your probes. Connect the probe to the calibration output (usually a square wave signal) and adjust the probe's compensation trimmer until a flat-top square wave is displayed on the screen.

4. Operating Instructions

4.1 Basic Operation

• Power On/Off: Press the POWER button located on the front panel to turn the device on or off.
• Navigation: Use the rotary encoders and function buttons (F1-F6, OK, MENU, etc.) to navigate through menus and adjust settings.
• AUTO Button: Press the AUTO button for automatic waveform adjustment, which quickly optimizes the display for the input signal.

4.2 Oscilloscope Function

The FNIRSI 1014D operates as a dual-channel digital storage oscilloscope with a 100MHz bandwidth and 1GSa/s sampling rate. It supports various trigger modes (Single, Normal, Auto) for capturing different types of signals.

Waveform Capture and Analysis:

• Adjust the VERTICAL controls (Position, CH1/CH2, CONF) to scale and position the waveform vertically.
• Use the HORIZONTAL controls (Position, ORIG) to adjust the time base and horizontal position of the waveform.
• The TRIGGER section allows you to set the trigger mode (MODE), trigger level (Level), and trigger edge (EDGE) to stabilize repetitive waveforms.

4.3 DDS Signal Generator Function

The built-in DDS signal generator can output various waveforms at adjustable frequencies. Press the GEN button to access the signal generator settings.

• Select from 14 types of function signals, including sine, square, triangle, and more.
• Adjust the frequency using the dedicated controls.
• Custom chopping signals can be stored and recalled.

4.4 Measurement Functions

The oscilloscope provides various measurement functions to analyze waveforms:

• Cursor Measurement: Use horizontal and vertical cursors to precisely measure amplitude, time, and frequency parameters directly on the screen.
• FFT Viewing: The Fast Fourier Transform (FFT) function allows for the estimation of the harmonic content of the signal, useful for spectral analysis.
• Lissajous Graphic Display: This function is used to compare the amplitude, frequency, and phase of two sets of signals, often used for phase shift analysis.

5. Care and Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the device. For stubborn dirt, a slightly damp cloth with mild detergent can be used, ensuring no liquid enters the device.
• Storage: Store the oscilloscope in a cool, dry place away from direct sunlight, extreme temperatures, and high humidity.
• Handling: Avoid dropping the device or subjecting it to strong impacts. Do not attempt to disassemble the unit, as this will void the warranty.
• Power Off: Always power off the device and disconnect it from the power source when not in use for extended periods or during cleaning.
