Frequently Asked Questions - FG-2602 VOLTCRAFT

How do I output a sine wave?

Press the Sine button on the front panel. Then use the menu keys (F1-F5) to set frequency, amplitude, offset. Turn the knob or enter numeric values. Press CH1 or CH2 to enable output.

What is the maximum output amplitude?

For high impedance load, up to 20 Vpp (≤25 MHz). For 50 Ω load, up to 10 Vpp (≤25 MHz). Above 25 MHz, amplitude reduces.

Can I generate an arbitrary waveform?

Yes. Press the Arb button, then choose a built-in waveform (45 types) or create a custom waveform via Editable Wform. You can define up to 1M points with 14-bit resolution.

How do I set modulation?

Press the Mod button, then select Mod (or Sweep/Burst). Choose modulation type (AM, FM, PM, PWM, FSK, ASK, PSK). Set parameters like frequency, depth, deviation using the menu keys and knob.

What does the 'Both' button do?

The Both button displays parameters for both channels simultaneously. You can edit the selected channel's waveform and parameters. The backlight indicates it is active.

How do I set the output load?

Press Utility → Output Setup → select CH1Load or CH2Load. Choose HighZ or a specific impedance (1 Ω to 10 kΩ). This matches the displayed voltage to the actual load.

Can I connect the generator to a PC?

Yes. Use a USB cable to connect the USB (type B) port on the rear panel to a PC. Install the Ultrawave software and driver from the CD. Then you can control the generator remotely.

The display is blank after power-on. What should I do?

Check the power cord connection, ensure the voltage selector is correct, and verify the fuse (250V F0.5AL) is not blown. If the problem persists, contact service.

How do I set the phase deviation between channels?

Press Utility → Output Setup → PhaseDev. Turn it On and set the angle from 0° to 360° using the knob or number keys.

What is the warranty period?

The product carries a 3-year warranty on materials and workmanship, and 1 year for accessories. It applies to the original purchaser and is not transferable.

For an external source, the depth of AM is controlled by the voltage level of the signal connected to the Ext Mod In connector in the rear panel. +1V corresponds to the currently set depth 100%.

FM (Frequency Modulation)

The modulated waveform consists of two parts: the Carrier Waveform and the Modulating Waveform. The Carrier Waveform can only be Sine. In FM, the frequency of the Carrier Waveform varies with the instantaneous voltage of the modulating waveform. The user interface of the FM is shown as below.

Appendix B: General Care and Cleaning

General Care

Do not store or leave the instrument where the liquid crystal display will be exposed to direct sunlight for long periods of time.

Caution: To avoid any damage to the instrument, do not exposed it to any sprays, liquids, or solvents.

Cleaning

Inspect the instrument as often as operating conditions require.

To clean the instrument exterior, perform the following steps:

1. Wipe the dust from the instrument surface with a soft cloth. Do not make any scuffing on the transparent LCD protection screen when clean the LCD screen.
2. Disconnect power before cleaning your instrument. Clean the instrument with a wet soft cloth not dripping water. It is recommended to scrub with soft detergent or fresh water. To avoid damage to the instrument, do not use any corrosive chemical cleaning agent.

Warning: Before power on again for operation, it is required to confirm that the instrument has already been dried completely, avoiding any electrical short circuit or bodily injury resulting from the moisture.
