Analyzing and Searching User-Defined Serial Bus Signals (User
Define)
Bus Setup (Setup)
You must set the following items to analyze user-defined serial bus signals.
Source (Source)
Set the analysis source to one of the settings below. The available settings vary depending on the model.
CH1 to CH4,* Math1 to Math4
* You can select CH4 when the key is illuminated.
Set the selected source’s active state, and level.
This item is the same as the trigger of a user-defined serial bus signal.
Level (Level) and Hysteresis (Hysteresis)
Set the level and hysteresis used to detect the source state.
These items are the same as those of the edge search.
Clock (Clock)
You can select whether or not to sample the data source in sync with the clock source.
• ON: Samples the data source in sync with the clock source
• OFF: Samples the data source according to the bit rate.
If you select ON, set the clock source (Clock), enable source (Enable), and latch source (Latch). You cannot
specify an enable or latch source on 2-channel models.
This item is the same as the trigger of a user-defined serial bus signal.
Bit Rate (Bit Rate)
The instrument samples the data source at the specified bit rate. Set the bit rate when the clock is OFF.
Selectable Range 1000 bps to 50 Mbps
Setting resolution 0.001 kbps (for 1.000 kbps to 99.999 kbps)
0.01 kbps (for 100.00 kbps to 999.99 kbps)
0.1 kbps (for 1 Mbps to 9999.9 kbps)
1 kbps (for 10 Mbps to 50 Mbps)
Decoding Start Point (Start Point)
Set the decoding start point.
Decoded Display (Decode)
The colors that are used for the fields in the decoded display are as follows: The decoded display can only be
used when the clock is not used.
Data: Cyan (Cyan)
Search Setup (Search)
Search Conditions (Condition Setup)
The method of setting search conditions is the same as that of setting the user-defined serial bus signal trigger
conditions.
Executing a Search (Search)
The instrument searches for locations where the specified search conditions are met. Then, the instrument
displays the specified detected point number (Pattern No) expanded in the zoom window.
Detected Points
The detected points are the same as the trigger points.
