Frequently Asked Questions - DS70304 Rigol
How do I perform an auto-setup on the DS70304?
Press the Auto button on the front panel. The oscilloscope will automatically adjust the horizontal, vertical, and trigger settings to display a stable waveform.
What is the maximum input voltage?
The maximum input voltage is 300 V RMS (CAT I). Use appropriate attenuation probes for higher voltages.
How do I update the firmware?
Download the latest firmware from Rigol's website, copy it to a USB drive, insert into the scope, and navigate to Utility > Update Firmware.
Can I measure differential signals?
Yes, use the Math function to subtract two channel inputs, or connect a differential probe to a single channel for floating measurements.
How do I calibrate the probes?
Connect the probe to the Probe Compensation output (1 kHz square wave) and adjust the compensation screw until the square wave appears flat.
What does the 'Run/Stop' button do?
Run continuously captures waveforms; Stop freezes the display to analyze a single acquisition.
How do I decode serial protocols like I2C or SPI?
Select Decode from the menu, choose the protocol, assign the clock and data lines, and set thresholds. The decoded data will appear at the bottom of the screen.
Why is the waveform not stable?
Adjust the Trigger Level and Trigger Slope. Ensure the trigger source matches the signal channel. Use Auto setup for quick stabilization.
How do I save a screenshot?
Press the Print button or navigate to Save/Recall to save a bitmap or CSV file to a USB drive.
What is the warranty period?
The standard warranty is 3 years from the date of purchase. Contact Rigol or your distributor for service.
