Description
A power-up sequence is a four-signal puzzle: two rails, an enable line and a reset all move within milliseconds. The Rigol DHO1204 oscilloscope puts four analog channels and an external trigger input on one 200 MHz, 12-bit bench scope. Lost in HCM lists it for rental and sale in Vietnam.
Why pick the Rigol DHO1204 oscilloscope
So four inputs let you see cause and effect on one screen. You can trace a supply rail, the signal it feeds and the control line between them, without swapping probes. Also, Rigol places the DHO1000 family in design verification, power electronics, embedded systems and automated test.
| Parameter | DHO1204 |
|---|---|
| Analog bandwidth | 200 MHz |
| Inputs | 4 analog plus external trigger |
| Maximum sampling | Up to 2 GSa/s |
| Memory | 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 |
| Screen | 10.1-inch 1280 x 800 capacitive touchscreen |
Catching the event you cannot predict
Fast capture matters when a fault appears once in a while. The UltraAcquire mode reaches up to 1,500,000 waveforms per second, so a short glitch has a better chance of landing on screen. Deep memory also lets you scroll back through the record. In addition, the high-resolution acquisition modes trade speed for finer vertical detail, up to 14 or 16 bit.
Everyday bench use
The product photo shows the DHO1204 front panel. Four color-coded BNC inputs sit along the bottom, and two USB ports sit on the left. Also, the 10.1-inch screen shows a waveform view with an FFT trace below it. Knobs and keys handle routine work, while the touchscreen handles zooming and cursors.
Rent a four-channel scope, or keep one
A rental suits a firmware bring-up, a power-supply debug sprint or a university course. Ownership, however, suits a bench that needs four channels every day. Either way, request a quote from Lost in HCM for the Rigol DHO1204 oscilloscope. Name the probe count, memory option, firmware and delivery site, because the listing is quote-led. Other models sit in the oscilloscopes category, Rigol keeps official documents at rigol.com, and you can contact SMK Vietnam for help.
DHO1204 questions
How does it differ from the two-channel model?
It adds two analog inputs. Bandwidth stays at 200 MHz on both the DHO1204 and the DHO1202.
How much memory does it have?
Standard memory is 50 Mpts, with up to 100 Mpts available as an option, so confirm which one your unit carries.
What should I confirm before ordering?
Check the model, serial number, firmware, bandwidth, channel count, memory option and installed licenses.
