Description
A four-wire serial bus such as SPI puts clock, data in, data out and chip select on separate lines. So the Rigol DHO1074 oscilloscope gives each line its own analog channel, with 70 MHz of bandwidth and 12-bit resolution. Lost in HCM lists it for rental and sale in Vietnam, and it quotes every configuration on its own.
Four probes for a four-line bus
Watching all four lines together shows which one moves first. You can then spot a late chip select or a clock that sags under load. An external trigger input also sits next to the four analog inputs, which helps when a separate event should start the capture.
Rigol DHO1074 oscilloscope in numbers
| Parameter | DHO1074 |
|---|---|
| Analog bandwidth | 70 MHz |
| Inputs | 4 analog plus external trigger |
| Maximum sample rate | Up to 2 GSa/s |
| Memory depth | 50 Mpts standard, up to 100 Mpts optional |
| Waveform capture | Up to 1,500,000 wfms/s in UltraAcquire mode |
| Vertical resolution | 12 bit, plus 14/16 bit high-resolution modes |
| Display | 10.1-inch 1280 x 800 capacitive touchscreen |
Rigol aims the DHO1000 family at design verification, power electronics, embedded systems and automated test. So this model fits a bench that debugs controllers and their power rails.
Memory and capture rate
The standard record holds 50 Mpts, and 100 Mpts is optional. UltraAcquire mode reaches up to 1,500,000 waveforms per second, so rare glitches have a better chance of showing up. In addition, 12-bit sampling keeps small steps visible next to large swings.
Decode, probes and licenses
Serial-bus decode is a feature to confirm, because the listing does not assume optional software. The same goes for probes, licenses and memory upgrades. Also state the attenuation ratio and the input voltage category you need. Then Lost in HCM can quote a unit that matches the job.
What the photo shows
The picture is a DHO1000 series reference. Four color-coded BNC inputs run along the bottom edge, while two USB ports sit at the left. The large screen shows a waveform view above an FFT trace.
Ask for the full configuration
Because the listing is quote-led, request a quote from Lost in HCM for the Rigol DHO1074 oscilloscope. Name the probe count, memory option, firmware and delivery site. Then compare other models in the oscilloscopes category. Rigol publishes datasheets at rigol.com, and you can contact SMK Vietnam when you need guidance.
DHO1074 questions
Is serial decode included?
Confirm it in the quote, because optional software, probes, licenses and memory upgrades are not assumed.
What is the difference between the DHO1074 and the DHO1072?
The DHO1074 has four analog inputs, while the DHO1072 has two. Both list 70 MHz of bandwidth.
Which details should I confirm first?
Verify the model and serial number first. Then confirm firmware, bandwidth, channel count, memory option and licenses, so nothing surprises you later.
