Description
Embedded debugging rarely stops at one trace. The Rigol DHO914S oscilloscope offers four analog channels at 125 MHz, plus 16 optional digital channels for logic work. Lost in HCM lists it for rental and sale in Vietnam, so a lab can borrow it for a project or buy it outright.
Four analog inputs, 12-bit resolution
Vertical resolution is 12 bit. That detail helps when a small ripple sits on a large rail, because finer steps show more of the signal. The DHO900 family also lists a 7-inch capacitive touchscreen with 1024 x 600 pixels, so you can pinch, drag and tap through a capture.
Sample rate and memory depend on channels
Both figures shrink as you switch on more inputs. The listing gives up to 1.25 GSa/s on one channel, 625 MSa/s on two and 312.5 MSa/s with all channels on. Memory follows the same pattern, at up to 50 Mpts, 25 Mpts and 10 Mpts. In addition, UltraAcquire mode reaches up to 1,000,000 waveforms per second.
| Item | Listed value |
|---|---|
| Analog bandwidth | 125 MHz |
| Inputs | 4 analog + 16 optional digital |
| Maximum sample rate | Up to 1.25 GSa/s (single channel) |
| Memory depth | Up to 50 Mpts (single channel) |
| Vertical resolution | 12 bit |
| Waveform capture | Up to 1,000,000 wfms/s (UltraAcquire) |
| Display | 7-inch 1024 x 600 capacitive touchscreen |
These values depend on the enabled channels, acquisition mode and installed options. Also confirm the current Rigol documentation before you apply any figure to a compliance test.
Who picks a 125 MHz scope
The listing positions the model for embedded debugging, education, serial-bus analysis and field work. For example, a firmware team can use the Rigol DHO914S oscilloscope to trace a UART or I2C line while a logic probe watches the chip select. A university can also rent several units for one semester, then decide whether to buy.
Request the Rigol DHO914S oscilloscope
Lost in HCM treats this listing as quote-led. Ask it to confirm the probes, options, firmware, calibration evidence and delivery terms for the exact unit. The photo shows a DHO900 family scope marked DHO924S, so check the label on your unit. Then request a quote from Lost in HCM and say whether you want to rent or buy. You can also browse oscilloscope listings, read the datasheets at Rigol, or contact SMK Vietnam.
DHO914S questions
Are the 16 digital channels included?
The listing calls them optional. Ask Lost in HCM whether the logic option and its probe come with the quoted unit.
How fast does it sample with all four channels on?
The listing gives 312.5 MSa/s with all channels on. The 1.25 GSa/s figure applies to a single channel.
Does the listing suit a teaching lab?
Yes, the listing names education among its uses. A rental also fits a single course term.
