[:SOURce<hw>]:BB:DM:PATTern <Pattern>
The command selects the data pattern for the internal data when PATTern is selected
as the data source. The maximum length is 64 bits.
Parameters:
integer
#B0,1 to #B111...1,64
#B0,1
<Pattern>
Range:
*RST:
BB:DM:SOUR PATT
selects Pattern as the data source for digital modulation.
BB:DM:PATT #B01110111010101010,17
generates the user-defined sequence of 0/1 data.
Example:
[:SOURce<hw>]:BB:DM:PRBS[:LENGth] <Length>
The command defines the length of the pseudo-random sequence in accordance with
the following equation:
Length = (2^LENGth) - 1
