CAN Bus Signal Analysis Function

2

Explanation

If you select CAN Bus for the cursor type, Cursor1 moves to the same position as when
you select Vertical cursors. Cursor2 moves to a position just one bit rate behind Cursor1.

The positions of reference cursors Ref1 and Ref2 remain at their previous settings.

Cursor1

Spacing between Cursor1 and Cursor2 (Bit Length)

You can change the spacing between Cursor1 and Cursor2 (firmware version 2.40 or later).
Selectable range: 1 to 1000 bits

Bit Rate

Select a data transfer rate for the CAN Bus data to be analyzed from the following.
10, 20, 33.333, 50, 62.5, 83.333, 95.238, 100, 125, 250, 500, or 1000 [kbps]
You can also enter an arbitrary value from the keyboard that appears on screen.
Selectable range: 10.000 to 1000.000 [kbps]

Resolution:

Bit time (reciprocal of the bit rate) resolution of 0.5

µ

s

Note

The bit rate setting is connected with the setting in the CAN Setup dialog box (see page 2-5),

and the Analyze Setup dialog box (see page 2-20).

Moving the Cursor to a Specified Field (Cursor Jump)

Cursor1 is displayed on the front of the specified field (SOF, Identifier, Control Field,
Data Field, CRC, or ACK). Cursor2 moves to a position just one bit rate* behind Cursor1.
The cursors move while maintaining a bit rate of space between them. You can also
display Ref1 at the front of the specified field, and Ref2 at the very back of the specified field.
* With firmware version 2.40 or later, the spacing between Cursor1 and Cursor2 is set

to “a bit rate x bit length.”

Note

•

When analyzing the CAN bus signal with the cursor type set to CAN Bus (see section 2.5),
Cursor1 moves to the front of the SOF field. Cursor2 moves to a position just one bit rate
behind Cursor1.

•

With the cursor type set to CAN Bus, when executing a jump to the specified field (See
“Jumping to a Specified Field” on page 2-26 and 2-34 in section 2.5), Z1 Pos, Cursor1,
and Ref1 move to the front of the specified field jump destination, Cursor2 moves to a
position one bit rate behind Cursor1, and Ref2 moves to the very end of the specified field

jump destination.
