Description
A service call gives you one chance to prove which part has failed, so the instrument case matters. The Rigol DHO802 oscilloscope is a compact 70 MHz scope with two analog inputs, an external trigger and a 7-inch touchscreen. Lost in HCM lists it for rental and sale in Vietnam, and it quotes each unit after a configuration check.
Why compact helps on a service round
Rigol places the DHO800 family in field service, education, embedded debugging and general electronics work. A smaller screen and body then suit a technician who carries the tool between plants. Two analog inputs also cover the usual pair of a test point and a reference.

Memory and speed in the field
Sampling reaches 1.25 GSa/s, and memory holds up to 25 Mpts. At the top rate, that spans about 20 ms. UltraAcquire mode captures up to 1,000,000 waveforms per second, so brief faults have a fair chance of appearing. Twelve-bit resolution also keeps small steps visible.
What the photo shows
The picture comes from the DHO800 series. A light gray panel carries a 7-inch screen with waveform, spectrum and results views, plus four BNC inputs and one USB port. This model has two analog inputs, so read the photo as a family reference.
Rent for a job, or own the tool
A rental suits a commissioning trip or a temporary repair desk. However, a service team that visits sites every week may prefer to own one. In either case, request a quote from Lost in HCM for the Rigol DHO802 oscilloscope. Ask which probes and accessories travel with the unit. You can also browse the oscilloscopes category, read official documents at rigol.com, or contact SMK Vietnam for advice.
DHO802 questions
Does it have four channels?
No. It has two analog inputs plus an external trigger, so pick the DHO804 if you need four.
Are probes part of the offer?
They may not be, because the listing is quote-led. So ask Lost in HCM to name every probe and accessory.
How big is the screen?
It is a 7-inch 1024 x 600 capacitive touchscreen, which keeps the body compact.
