Description
Four channels run out quickly on a board with a bus, a clock and several rails. The Keysight EXR258A oscilloscope answers that with eight analog channels and 2.5 GHz of bandwidth in the Infiniium EXR-Series. Lost in HCM lists it for rental and sale in Vietnam.

Each extra input on the Keysight EXR258A oscilloscope removes a repeat run. Instead of capturing the supply, then the bus, then the clock, you probe them together and keep one trigger point. As a result, cause and effect sit on the same time axis.
Multi-phase and multi-rail work
A three-phase converter shows the value well. Three phase voltages and three currents already fill six inputs, and two more can watch a gate drive or a fault line. A controller with many outputs, or a sequencer that brings up rails in turn, follows the same logic.
Eight inputs need eight probes, so count them early. Probe type and fixture quality still limit what you can trust at the edges.
The Keysight EXR258A oscilloscope on a shared bench
Also, a scope with this many inputs often serves several people. Before it ships, agree on a short acceptance list: identity, condition, start-up, self-test, installed options, accessories and calibration papers. Then note who may use it, how to book it and who looks after the connectors. For automated work, also keep driver versions, command examples and saved setups, so the next engineer can repeat your result.
Where eight channels pay off
- Power electronics with several phases to watch together.
- Controller boards with parallel outputs and a shared clock.
- University labs that want one instrument to cover many experiments.
Ask Lost in HCM about the EXR258A
Rent for a project with a known end date, or ask for a purchase quote if the bench will use it daily. Either way, request a quote from Lost in HCM and list your signal count, probes and delivery city. Other oscilloscope listings sit one click away, and the Keysight website also has the maker’s own pages. Need help with this listing? Just contact SMK Vietnam.
EXR258A questions
Why pick eight channels instead of four?
Eight inputs let one capture hold more of the system, so you repeat fewer runs. The cost is more probes, so count them before you order.
Can SMK Vietnam ship the EXR258A to my site?
SMK Vietnam only shows the listing. Lost in HCM gives the quote, so send your delivery city and dates to them.
Which options should I name in the request?
Name probes, MSO capability, analysis licenses, memory and interfaces. The listing asks you to confirm each one for the exact unit.
