Description
A microcontroller board resets at random, and the cause could be a sagging rail or a firmware fault. The Rigol MSO2102A oscilloscope lets you watch the rail on an analog channel and the reset and bus lines on 16 digital channels. Lost in HCM lists it for rental and sale, and it arranges service on request.
Analog rail, digital lines, one screen
With the Rigol MSO2102A oscilloscope, probe the supply rail on an analog input, then follow the reset line, a chip select and a serial bus on the logic channels. Because all of them share one timebase, you can read which event came first. That answer also separates a hardware dip from a software stall. At 100 MHz, the scope still covers most microcontroller-class signals.

Options, acquisition mode and firmware can change these figures, so confirm them in the quotation.
The logic probe note
The listing says the digital channels need the RPL2316 probe. Therefore, ask for it by name in your request. Do not assume it ships with the scope, because the listing does not promise accessories.
Plain model or -S model?
The MSO2102A-S carries the same listed analog and logic figures and adds an integrated 2-channel 25 MHz generator. Pick the plain MSO2102A when you already own a signal source. Otherwise, pick the -S when you want stimulus and measurement in one case.
Rent or buy for your lab
For example, a rental covers a firmware push or a board revision that ends on a known date. However, buying the Rigol MSO2102A oscilloscope suits a bench that sees a new design every month. Lost in HCM supplies the unit and gives the quote, while SMK Vietnam only shows the listing. Start with a quote request to Lost in HCM that lists your probes and delivery site. The oscilloscope category shows related models, Rigol keeps the manuals, and SMK Vietnam can help with an order.
MSO2102A questions
Which accessory does the logic side need?
The listing says the RPL2316 probe is required for the 16 digital channels. Ask Lost in HCM to include it in the quote.
How does it differ from the MSO2102A-S?
Mainly the generator. The -S lists an integrated 2-channel 25 MHz source, while this model lists none.
What bandwidth and sample rate does it list?
It lists 100 MHz of analog bandwidth and up to 2 GSa/s. Channel use and options can change those figures.
