MDO4000C Series vs. Keysight InfiniiVision 4000 X-Series
COMPETITIVE FACT SHEET
Importance of Reliable Measurements and Accurate Search
Keysight 4000 X-Series
Tektronix MDO4000C Series
P
Selectable record length maintains sample rate resolution
and gives the user control
O
User can NOT select record length, only horizontal
scale, resulting in highly distorted waveform
P
20 M record length on all channels and at all settings = 10X
more timespan at the same sample rate, allowing users to
see more of the waveform and signal
O
Record length drops from 4M to 2M when more than 2
channels are turned on or when continuous run mode is
used; reduced again when digital channels are used
P
Wave Inspector® controls for easy scrolling through long
records
O
Limited navigation buttons and multiplexed
horizontal controls
P
Measurements and search based on signal data values
reliably find specified events (see screen capture “7 events
found”)
O
P
Automated Search Mark Table allows user to see timing
intervals between search events
Measurements and search based on displayed data
points resulting in values changing based on zoom
settings, search not reporting all events captured (see
screen capture “>=0 events found”)
O
Lack of search mark table and missing search events
make finding root cause difficult
P
Ability to copy trigger setting to search reduces setup steps
O
No ability to copy trigger setting to search, increasing
work needed to set up common search tasks
Maintain sample resolution
at long time spans
7 search events found
