Never let a lack of channels slow down your verification and debug process again!

The 4 Series MSO offers better visibility into complex systems by offering four and six-channel models with a 13.3-inch high-definition (1,920 x 1,080) display. Many applications, such as embedded systems, three-phase power electronics, automotive electronics, power supply design, and DC-to-DC power converters, require the observation of more than four analog signals to verify and characterize device performance, and to debug challenging system issues.

Most engineers can recall situations in which they were debugging a particularly difficult problem and wanted greater system visibility and context, but the scope they were using was limited to two or four analog channels. Using a second scope involves significant effort to align trigger points, difficulty in determining timing relationships across the two displays, and documentation challenges.

And while you might assume that a six-channel scope would cost 50% more than a four-channel scope, you'll be pleasantly surprised to find that six-channel models are only ~20% more than four-channel models. The additional analog channels can pay for themselves quickly by enabling you to keep current and future projects on schedule.
