18 Guaranteed Specs Mean Your Scope Meets these Specs
Minimizing uncertainty allows you to be more confident in your product specifications and more competitive. Tektronix guarantees 18
specifications on the MDO3000 Series, but Keysight only guarantees 4 specifications on the 3000T X-Series; the rest are just stated
as typical. How do you know if your Keysight scope is typical?

Probe Loading Degrades Your Measurements
Our engineers have worked hard to minimize the impact. Tektronix TPP-Series probes
have less than 4 pF of capacitive loading and they’re included with every MDO3000. The
probes included with the Keysight 3000T X-Series have 11 to 12 pF of loading. Excessive
loading can result in inaccurate measurements and even change circuit behavior.
And why buy a 1 GHz scope if you are going to filter the signal with a 500 MHz probe?
Probes that match the bandwidth of the scope enable full utilization of the scope.
All Tektronix MDO3000 Series oscilloscopes include probes that are at least the
bandwidth of the oscilloscope. The Keysight 1GHz 3000T X-Series oscilloscope
includes 500MHz probes.
