Range
1|…|32
Delta Length
Sets the zero interpolation of the code to create a sync symbol (Si) for UWB
synchronization header (SHR). Available Delta Length choices also depend on which
"Channel" on page 487 is selected, as described in Table 15-4 of the IEEE 802.15.4
standard.
Remote
Command
[:SENSe]:HUWB:SHR:DELTa:LENGth L4 | L16 | L64
[:SENSe]:HUWB:SHR:DELTa:LENGth?
Example
:HUWB:SHR:DELT:LENG L64
Couplings Only value 4 (L4) can be used when SHR Code Index is from 9 to 32
Only value 16 (L16) can be used for wideband channel (channel number 4, 7, 11, 15) when SHR Code
Index is from 1 to 8
Values 16 (L16) and 64 (L64) can be used for other channels when SHR Code Index is from 1 to 8
Preset
L16

SYNC Length
Sets the number of sync symbol (Si) used to comprise the SYNC portion for UWB
synchronization header (SHR).

Couplings Valid values depend on "PHY Mode" on page 501:
PHY Mode Valid Values
Non-ERDEV 16, 64, 1024 and 4096 symbols (L16, L64, L1024, L4096)
Note that 4096 is not allowed if "Delta Length" on page 504 is 64
ERDEV-BPRF PHY 16, 64, 1024 and 4096 symbols (L16, L64, L1024, L4096)
ERDEV-HPRF PHY 16, 24, 32, 48, 64, 96, 128, and 256 symbols (L16 -L256)
Preset
L64
