4.1. Išpakavimas ir patikrinimas

Carefully remove the instrument from its packaging. Inspect the unit for any signs of physical damage that may have occurred during transit. If any damage is found, contact your supplier immediately.

4.2. Maitinimo prijungimas

Connect the supplied AC power cord to the power input receptacle on the rear panel of the instrument and then to a suitable grounded AC power outlet. Ensure the voltage rating of the instrument matches your local mains supply.

4.3. Pradinis įjungimas

Press the Power button on the front panel. The LED frequency display should illuminate, indicating the unit is powered on. Allow a few minutes for the instrument to warm up and stabilize before taking precise measurements.

5. Naudojimo instrukcijos

5.1. Pagrindinė bangos formos generavimas

1. Maitinimas: Ensure the instrument is powered on as described in Section 4.3.
2. Pasirinkite bangos formą: Press the desired waveform button (e.g., Sine, Square, Triangle) to select the output waveform.
3. Select Frequency Range: Press one of the Frequency Range buttons (e.g., 1K for 1 kHz to 10 kHz range) to set the approximate frequency range.
4. Reguliuoti dažnį: Naudokite Grubus ir gerai frequency knobs to set the exact desired frequency. The LED display will show the current frequency.
5. Adjust Output Level: Pasukite Išvesties lygis knob to set the ampišėjimo signalo apšvietimas.
6. Prijungti išvestį: Connect your test equipment (e.g., oscilloscope) to the Išvestis BNC jungtis.

5.2. Using the Sweep Function

The sweep function allows the output frequency to vary automatically over a defined range and time.

1. Set up a basic waveform as described in Section 5.1.
2. Select Sweep Mode: Naudokite Log/Int switch to select between linear or logarithmic sweep.
3. Adjust Sweep Time: Naudokite Laikas knob in the SWEEP section to set the duration of the sweep cycle.
