FAQs
What waveforms can the SFG-1013 generate?
The SFG-1013 can generate sine, rectangle, and triangle waveforms.
What is the maximum frequency output?
The maximum frequency output is 3MHz.
Does it have a TTL output?
Yes, the SFG-1013 includes a dedicated TTL output.
Is this generator suitable for complex signal modulation?
No, this model is designed for basic signal generation and does not support complex modulation features.
How accurate is the frequency output?
The SFG-1013 provides high accuracy and stability due to its DDS technology, suitable for its intended applications.
What type of connector does the output use?
The output uses a standard BNC connector.
Can I generate arbitrary waveforms with this model?
No, this model is limited to sine, rectangle, and triangle waveforms. Arbitrary waveform generation requires more advanced function generators.
Troubleshooting
No output signal
Ensure the output is enabled, check cable connections, and verify the frequency and amplitude settings are appropriate.
Waveform distortion
Check the load impedance; ensure it is within the generator's specifications. Verify the frequency is not at the extreme upper limit where accuracy might decrease.
Inaccurate frequency reading
Allow the generator to warm up for a few minutes for maximum stability. Ensure the selected frequency is within the specified accuracy range for the instrument.
Unit does not power on
Verify the power cord is securely connected to both the unit and a working power outlet. Check the fuse if applicable.
