"Manchester" Selects the coding standard Manchester.
Optional "Timing settings" are "Bit Rate" (default: disabled, 10
Mbit/s)
and "Gap time" (default: disabled, 10 µs).
"Manchester II" Selects the coding standard Manchester II, which is the inverted sig-
nal of the coding standard Manchester.
Optional "Timing settings" are "Bit Rate" (default: disabled, 10
Mbit/s)
and "Gap time" (default: disabled, 10 µs).
"NRZ Clocked" Selects the coding standard NRZ Clocked.
"NRZ
Unclocked" Selects the coding standard NRZ unclocked.
Remote command:
BUS<m>:CMSB:CODing
on page 1753
Data Source
Defines the input source for the custom serial bus data signal.
The data source for Manchester and NRZ coding standards is selected separately,
independent of each other. The data source is set to default upon switching the coding
standard.
Permitted source selections are:
●
For "Manchester"/ "Manchester II":
–
Decoding: the analog, mathematical, and reference channels
– Triggering: the analog channels
●
For "NRZ Clocked":
–
Decoding: the analog, mathematical, reference and digital channels
Digital channels can be only used if MSO option R&S
RTO6-B1 is installed.
Digital and analog channels cannot be used at the same time.
– Triggering: the analog and digital channels
●
For "NRZ Unclocked":
–
Decoding: the analog, mathematical, reference and digital channels
Digital channels can be only used if MSO option R&S
RTO6-B1 is installed.
Digital and analog channels cannot be used at the same time.
– Triggering: the analog channels
Remote command:
BUS<m>:CMSB:MANChester:DATA

BUS<m>:CMSB:NRZ:DATA
on page 1756
Clock Source
Defines the source for the custom serial bus clock signal (only available for the coding
standard "NRZ Clocked").
Permitted source selections are the analog, mathematical, reference and digital chan-
nels.
Digital channels can be only used if MSO option R&S RTO6-B1 is installed. Digital and
analog channels cannot be used at the same time.
For triggering on the serial bus, when the NRZ clocked coding standard is selected,
analog or digital channel sources are required.
Custom: Manchester / NRZ (option R&S RTO6-K510)
