Frequently Asked Questions - DG2072 Rigol
How do I output a sine wave on both channels?
Press the Channel key to select channel 1 or 2. Use the Waveform key to choose Sine. Set frequency and amplitude using numeric keypad or knob. Repeat for the other channel.
What is the maximum output frequency?
The DG2072 has a maximum bandwidth of 70 MHz for sine waves. For other waveforms, the maximum frequency may be lower.
Can I connect this generator to a PC?
Yes, via USB or LAN. Install the UltraSigma software from Rigol's website for remote control and waveform editing.
How do I create an arbitrary waveform?
Use the Arb function. You can edit waveforms on the front panel or upload a CSV/WAV file via USB using the UltraStation software.
What does the 'Sync' output do?
The Sync output provides a TTL signal synchronized with the main output. Useful for triggering other instruments.
How do I set the output amplitude in dBm?
Press the Ampl key, then use the softkey to switch units to dBm. The range is typically -50 dBm to +20 dBm.
Why is my output distorted at high frequencies?
Check the load impedance. The generator expects a 50 Ω load. If driving a high impedance, use a 50 Ω feedthrough terminator.
Can I use the generator to produce a sweep?
Yes, press the Sweep key. Set start/stop frequency, sweep time, and choose linear or logarithmic sweep.
How do I update the firmware?
Download the latest firmware from Rigol's support page. Copy the .GEL file to a USB drive, insert into the generator, and follow the upgrade menu.
What is the warranty period?
Rigol offers a 3-year warranty for the DG2072. Register your product online to activate warranty.
