Deeper memory allows you to capture longer time windows while maintaining a high sample rate, which is crucial for finding intermittent glitches.
When looking for a used unit, prioritize these specifications based on your needs: buy used oscilloscope
This determines the highest frequency signal you can measure. For general hobbyist work, aim for at least 50–100 MHz . Deeper memory allows you to capture longer time
Test all knobs and buttons. Rotary encoders (the knobs on DSOs) are common failure points; ensure they don't skip or lag. buy used oscilloscope
Look for a rate at least 2.5 to 10 times your bandwidth for accurate waveform representation.
If buying locally, perform these checks to verify functionality:
Professional refurbished units from manufacturers like Keysight are calibrated and often come with a warranty. Essential Pre-Purchase Tests
