WaveBPS: Event List Columns

Each column in the event list represents an automatic measurement. This document describes each column present. Different decoders support different automatic measurements. Clicking on any automatic measurement will change zoom view to the time that measurement was made.

Table 1 - General Columns

Name	Description	Notes
TStart	Start time of the event. The icon signifies the channel and if there are any warnings or errors in this event.
TWidth	The width of the event in time.
T-IFS	The time since the last event.	Use for testing diagnostic response messaging which requires specific delays.
ErCnt	Indicates how many errors this event has	Use with filter to quickly find events that have errors
WrnCnt	Indicates how many warnings this event has
ID
Node	Name of the node sending this event (requires a data base)	When enabled with a data base this enables statistical node analysis on automatic measurements.
Data	shows the data for the event

Table 2 - FlexRay Columns

Name	Description
Res	The FlexRay reserved bit
PPI	Payload preamble indicator bit
Null	Null frame bit
Sync	sync frame bit
Start	startup frame bit
Ch	the flexray channel a or b
H-CRC	the header crc
CycCount	the current cycle count
CRC	the CRC - will be different for channel a and b
TSS (bits)	transmission start sequence measurement in bits
Dyn	indicates whether this is a dynamic frame
Len	Length of the data section in words

Table 3 - CAN Columns

Name	Description
RTR	Remote transmit request bit
IDE	Identifier extension bit
RB0	reserve bit 0
RB1	reserve bit 1
HiV (SWCAN ONLY)	For single wire can this indicates the transmitter of the message is using the transceiver's High voltage mode
HiAck (SWCAN ONLY)	For single wire can this indicates the ack bit is high voltage meaning at least one receiver is using the high voltage mode of the transceiver
HiSpd (SWCAN only)	for single wire can this indicate the a high speed transition has occurred and is operating at the high bit rate
SRR	Standard frame remote request bit
Len	Length of data frame in bytes
CRCDel	The CRC Delimiter space
Ack	The acknowledgement bit
AckDel	the acknowledgement delimiter bit
CRC	The 15 bit CRC checksum
Stuffs	how many stuff bits are present in the CAN message
BitTol	The bit tolerance. The bits controlled only by the transmitter are measured between two recessive to dominant edges. This time is compared with the ideal bit time.
MinV	Here a minimum voltage is measured across the bits controlled by the transmitter (after the ID and before the Ack bit)
MaxV	Here a maximum voltage is measured across the bits controlled by the transmitter (after the ID and before the Ack bit)
AckSkew	The measures the time difference between the ideal starting ack position and the actual one
AckWidth	This measures the width of the ack bit
DataPercent	This measures the payload percentage of the message. This is how much data was sent compared to how long the entire frame requires.

Table 4 - LIN Columns

Name	Description
Brk(bits)	Length of sync break in bits
Sync	value of the sync byte
TSlvRsp	Time between the master header and the slave response
THeader	Length of the master header in time
TResponse	Length of the entire slave response
TMaxUtil	This the length of the frame compared to the ideal length * 40% allowed by the LIN specification
Len	This is the length of the frames data section.
ChkSum	This is the checksum of the LIN message. Both standard and enhanced are calculated.

Table 5 - J1850 VPW Columns

Name	Description
SOF	The length of the start of frame symbol in time
Len	the length of the message in bytes
CRC	The CRC check sum
IFR	In-frame response data (chrysler implementation only)

Table 6 - UART Columns

Name	Description
Brk(bits)	the number of bits of a UART break if present
Len	the length of the data section
Data (ASCII)	The data section represented as ascii characters

Table 7 - I2C Columns

Name	Description
AddrLen	The length of the I2C address either 7 or 10 bits
R/W	This indicates if it is an I2C write or read
Address	This is the address of the message
Len	This is the length of the data
