Description
Some faults only make sense when you see an analog rail and a logic bus at the same instant. The Rigol MSO8074A oscilloscope puts four analog channels and 16 digital channels on one timebase, with 750 MHz of bandwidth. Lost in HCM lists it for rental and sale, and it arranges service on request.
Analog and logic on one screen
Four analog inputs let you watch supply rails, clocks and sensor outputs. In addition, the 16 digital channels follow a bus or a set of control lines. The listing says those channels need a logic probe, so ask for one in your quote. Then a dip on a rail and the bus error it causes appear side by side.
MSO8074A figures
| Item | Value |
|---|---|
| Analog bandwidth | 750 MHz |
| Inputs | 4 analog, external trigger, 16 digital (logic probe needed) |
| Sample rate | Up to 10 GSa/s, channel-mode dependent |
| Memory depth | Up to 500 Mpts, channel-mode dependent |
| Capture rate | Up to 600,000 waveforms per second |
| Vertical resolution | 8 bit native, plus high-resolution modes |
| Display | 10.1-inch capacitive touchscreen |
Channel mode, options and firmware can move these values, so the quotation has the final word.
Where 750 MHz fits
The Rigol MSO8074A oscilloscope is the lowest class among the MSO8000A listings here. It suits boards whose signals sit in the hundreds of megahertz, such as controller boards, power rails and moderate-speed buses. Rigol positions the family as a laboratory scope for high-speed signal inspection, timing analysis and design verification. Choose a higher class only when your fastest edge demands it.
Working on the touchscreen
The capacitive screen keeps menus and measurement tables a tap away. The product photo shows a histogram window over an eye diagram, plus three USB ports and four color-coded inputs. However, it is a family view marked MSO8304A, so check the marking on the unit you receive.
Rent or buy the Rigol MSO8074A oscilloscope
A rental suits a board bring-up that wraps up in a few weeks. Buying suits a lab that debugs mixed-signal hardware every day. SMK Vietnam only shows the listing, while Lost in HCM supplies the unit and gives the quote. To start, request a quote from Lost in HCM with your probe list and delivery site. Related models appear in the oscilloscope category, and Rigol holds the maker’s documents. If you need help with an order, contact SMK Vietnam.
MSO8074A questions
Is the logic probe included?
The listing says the 16 digital channels need a logic probe. It does not promise one in the box, so ask in your quote.
How does it differ from the MSO8154A?
Bandwidth is the difference. This model lists 750 MHz, while the MSO8154A lists 1.5 GHz with matching figures otherwise.
Does the top sample rate apply on every channel?
Not always. The listing says up to 10 GSa/s and notes that the figure depends on the channel mode.
