Description
Powering up a board with several rails means watching several signals at once. A Tektronix TBS2204B oscilloscope gives you four analog channels and 200 MHz of bandwidth, so you can compare circuit nodes in the same capture. Also, it is a bench scope for everyday troubleshooting.

Sample rate depends on active channels
The top rate is 2 GS/s when half the channels are active. With all four channels on, it drops to 1 GS/s. So plan a capture around the number of channels you really need.
A long record helps here, because it holds a slow event and still keeps detail. For example, you can trace a supply ramp and zoom into one glitch afterward.
Probes and grounding
The TekVPI interface works with compatible probes, so confirm the exact probe type for your test. A normal passive probe ties its ground lead to circuit reference. Never clip that lead to a live mains conductor or an arbitrary floating node.
When the circuit calls for it, use a correctly rated differential or isolated measurement system instead. Then check the manual for the grounding rules of both the scope and the probe.
Who books a Tektronix TBS2204B oscilloscope
- Maintenance teams that diagnose control boards.
- Training labs that need identical benches.
- Production engineers who add a station for a peak.
- R&D groups that need a spare four-channel scope.

Tektronix TBS2204B oscilloscope questions
What sample rate do I get with four channels on?
You get 1 GS/s with all four channels active, and 2 GS/s when only half are active.
Do probes come with the scope?
Confirm probes and accessories in the quote, because the delivered configuration can differ.
How long is the record?
It holds 5 million points, so a slow event still keeps its detail when you zoom in.
