Digital Channels 7
Keysight InfiniiVision HD3-Series Oscilloscopes User's Guide 117
• When capturing data in a noisy environment, every third digital channel probe's
ground should be used in addition to the channel group's ground.
• High-speed timing measurements (rise time < 3 ns) should make use of each
digital channel probe's own ground.
When designing a high-speed digital system, you should consider designing
dedicated test ports that interface directly to the instrument's probe system. This
will ease measurement setup and ensure a repeatable method for obtaining test
data. The 01650-61607 16-channel logic probe cable and the 01650-63203
termination adapter are designed to make it easy to connect to industry-standard,
20-pin board connectors. The cable is a 2 m logic analyzer probe cable, and the
termination adapter provides the proper RC networks in a very convenient
package. These parts, as well as the 1251-8106 20-pin, low-profile, straight board
connector, can be ordered from Keysight Technologies.
