Measurements
Tektronix MSO/DPO5000B
✔ Two multipurpose controls for convenient cursor contro
✔ Automated measurements can be gated by cursors or by any of the 4 zooms
✔ Automatic measurements based on signal data values
Agilent X 4000A Series
Single, multiplexed cursor control
✔ Automated measurements can be gated by zoom or cursors
Automatic measurements based on displayed data points
Graphical Triggering
Tektronix MSO/DPO5000B
✔ Visual Trigger is standard and is integrated into the trigger setup interface
✔ Up to 8 user-definable regions
✔ Visual Trigger areas can be associated with any of the analog channels
✔ Visual Trigger areas can be moved, resized, and shapes can be modified
✔ Visual Trigger setup can be horizontally scaled and used with search
Graphical Triggering
Agilent X 4000A Series
✔ Zone triggering is standard and has a separate front panel button user interface
Limited to 2 rectangular zones max.
Limited to a single analog channel
Zones can be moved, but not resized, and shape can’t be modified
Zone triggering can’t be horizontally scaled significantly and doesn’t work with search
Graphical Triggering
Automated Search
Tektronix MSO/DPO5000B
✔ Simultaneously search for up to 8 different events
✔ Search on variety of digital features including Setup/Hold, Logic, serial or parallel buses
✔ Search based on signal data values, reliably finding specified events (see below, finding 3 runts and 3 glitches)
Automated Search
Agilent X 4000A Series
Search for a single event at a time
Limited search capabilities – no Setup/Hold, Logic, or parallel bus.
Search based on displayed data points and does not reliably find events (see example, showing “>=0 events found”)
Automated Search
Digital Channels
Tektronix MSO5000B
✔ Record lengths up to 40 Mpoints, even with analog channels on.
✔ Channel-to-channel skew 500 ps typical.
✔ MagniVu extends digital channel timing resolution down to 60.6 ps.
✔ Bus waveforms can be moved within the display. Up to 16 buses.
✔ Event table for parallel bus decode.
Automated Search
Agilent MSO-X 4000A Series
Maximum record length 2 Mpoints with no analog channels on, reduced with analog channels on.
Channel-to-channel skew 2 ns typical.
Digital channel sample rate of 1.25 GS/s gives 800 ps timing resolution.
Bus waveforms anchored to bottom of the display.
No event table for parallel bus decode.
