Remote command:
BUS:SENT:DNIBbles on page 480
Pause Pulse
Determines whether a pause pulse is transmitted after the checksum nibble.
You can use this pulse to create a transmission with a constant number of clock ticks.
The pause pulse length can be between a minimum of 12 clock ticks up to 768 (3*256)
ticks at a maximum.
"No"
No pause pulse between the transmission sequences.
"Yes"
Pause pulse with fixed length at the end of each transmission
sequence.
The R&S RTH computes the length of the pause pulse automatically.
"Constant frame length"
Pause pulse with dynamic length to maintain a fixed transmission
sequence length.
To define the constant frame length, set the number of clock ticks
under "Frame Length" on page 235.

CRC Calculation
Selects the method for CRC calculation.
SENT CRC calculates the checksum over all nibbles except the communication and
status nibble.
"SAE_J2716"
Calculates the CRC according to the SAE standard.
"TLE_4998X"
Calculates the CRC according to the standard computing method for
Infineon TLE_4998X sensors.
Remote command:
BUS:SENT:CRCMethod on page 480
CRC Version
Selects the version the CRC check is based on.
"Legacy"
Based on the CRC calculation version used earlier than 2010.
"v2010, v2016"
Based on the recent CRC calculation version updated in 2010/2016.

Frame Length
Determines the frame length in terms of ticks. The dialog displays this settings parame-
ter, if the signal has a constant frame length.
