Our Testing Experience

First Impressions

When I first unpacked the Rigol DS1104Z-S Plus, I was impressed by its compact size and solid build. It felt sturdy but not heavy, which made setting it up on my small workbench easy. The 4.818888 x 6.330696 x 12.326747 inch dimensions meant it didn’t take up too much space. I connected it quickly and was happy to see the bright, clear display. The menu was straightforward, so I could start testing signals without digging into the manual too much.

Daily Use

Using the oscilloscope daily for various projects was a smooth experience. The 4 channels allowed me to monitor multiple signals at once, which was a big help. I especially liked the built-in 25 MHz function/arbitrary waveform generator because it saved me from needing an extra device. The free BND-MSO/DS1000Z software bundle built into the unit made data analysis simpler and faster. I found myself relying on the digital logic connector and the optional MSO upgrade (RPL1116) when working on mixed signal designs, which added great flexibility.

Key Features in Action

The 100 MHz bandwidth and 1 GSa/s sampling rate really stood out during my tests. Signals appeared crisp and clear, making troubleshooting easier. The large 24 Mpts memory depth meant I could capture long signal sequences without missing details. Having 16 digital channels was a big plus for logic analysis, especially when combined with the analog channels. The dual 25 MHz signal sources came in handy for creating test signals on the fly. Overall, these features helped me work faster and more accurately.

Long-Term Performance

After using the Rigol DS1104Z-S Plus for several months, it still performs reliably with no glitches or slowdowns. The interface remains responsive, and the signal quality is consistent. I appreciate that the firmware updates are easy to install, keeping the scope up to date with new features. The device has become an essential tool in my lab, handling everything from simple repairs to complex circuit debugging without any trouble.
