Description
A production-test station often needs only two probes, one on the output and one on a trigger point. So the Rigol DHO1072 oscilloscope fits well, with 70 MHz of bandwidth, two analog inputs and 12-bit vertical resolution. Lost in HCM lists it for rental and sale in Vietnam, so you can borrow one before you commit.
Where the Rigol DHO1072 oscilloscope fits
Rigol places the DHO1000 family in design verification, power electronics, embedded systems and automated test. At 70 MHz, this model also handles power rails, control signals and many slower buses. An external trigger input sits beside the two analog inputs, so a separate event can start a capture.
| Parameter | DHO1072 |
|---|---|
| Analog bandwidth | 70 MHz |
| Inputs | 2 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 |
Depth and detail on a short record
Memory runs 50 Mpts as standard, while up to 100 Mpts is optional. At the top rate of 2 GSa/s, 50 Mpts holds about 25 ms, because depth divided by rate sets the window. Slower sampling then stretches the record. In addition, the 14 and 16 bit modes give finer vertical detail on quiet signals.
Typical two-channel checks
Start with a supply rail on one channel and a reset line on the other. Then watch how the rail dips when the controller wakes up. A sensor output and its filtered copy make another pair, so you can see how much noise the filter removes. For example, a line audit may repeat the same pair of checks on every station.
Read the photo with care
The product photo comes from the DHO1000 series. It shows four BNC inputs, two USB ports and a screen with waveform and FFT views, while this model has two analog inputs. So treat the picture as a family reference.
Rent or buy a two-channel bench scope
A rental suits a line audit, a short qualification run or a teaching term. Ownership, however, suits a bench that runs two-channel checks every day. Either way, request a quote from Lost in HCM for the Rigol DHO1072 oscilloscope. The listing is quote-led, so ask for the exact probes, firmware and options. You can also browse the oscilloscopes category. Rigol keeps official documents at rigol.com, and you can contact SMK Vietnam for help.
DHO1072 questions
Do probes come with the scope?
Not by default, because the listing is quote-led. So ask Lost in HCM to name the probes, adapters and cables.
Can I step up to 100 MHz?
Yes. The DHO1102 offers 100 MHz with the same two analog inputs, so it makes a natural upgrade path.
How long a record fits in memory?
At 2 GSa/s, 50 Mpts covers about 25 ms. Slower rates also stretch that window.
