Description
Edges get faster with every product generation, and a slow scope rounds them off. Here, the Keysight EXR204A oscilloscope offers 2 GHz of bandwidth on four analog channels, as part of the Infiniium EXR-Series. Lost in HCM lists it for rental and sale in Vietnam.
Speed first, four channels
| Item | Listed value |
|---|---|
| Instrument type | Infiniium EXR-Series oscilloscope |
| Bandwidth | 2 GHz |
| Analog channels | 4 |
This model favors bandwidth over input count. Four channels still cover a clock, a data line and two control signals. Meanwhile, 2 GHz gives headroom for the fast transitions you want to judge honestly. The Keysight EXR204A oscilloscope therefore suits teams that care about edge shape more than channel count.
Where the Keysight EXR204A oscilloscope fits
- Judging ringing and overshoot on short interconnects.
- Checking clock quality on high-speed boards.
- Looking at fast switching transitions in compact power stages.
- Comparing a prototype with a reference design.
Bandwidth is not the whole story
Bandwidth describes the analog front end. It does not tell you the sample rate, and the listing gives none. So ask Lost in HCM for the figure if your analysis depends on it. Probes and fixtures also shape the result, so plan the whole signal path.
Details the quote should name
The listing names probes, MSO capability, analysis licenses, memory, interfaces and calibration as items to confirm. Put each one in your request. Then the unit that arrives matches your test plan. Also, because a high-bandwidth setup is easy to spoil, ask for the probe tips and ground accessories as well.
Short sprint or standing bench
Rent for a high-speed bring-up or a research peak. Ask for a purchase quote if the same edges need checking every week. Then request a quote from Lost in HCM with your dates and delivery city. You can also browse oscilloscope rentals, visit the Keysight website or contact SMK Vietnam.
EXR204A questions
Is 2 GHz bandwidth the same as sample rate?
No. Bandwidth describes the front end. The listing gives no sample rate, so ask Lost in HCM if you need one.
Why pick four channels at 2 GHz?
Choose it when a few fast signals matter more than a wide view of many slow ones.
What else should I check besides bandwidth?
Check probes, MSO capability, analysis licenses, memory, interfaces and calibration for the exact unit.
