Select the pattern to be inserted in the transmitted signal.
OffOff: Does not insert the pattern.
User [32] bitUser [32] bit, User [2048] bitUser [2048] bit: 32 bits or 2048 bits length pattern.
PRBS 6PRBS 6 to PRBS 23PRBS 23: Pseudo-random bit sequence. The number indicates the
bit length of sequence.
For example, bit length of PRBS 9 is 2
9
-1=511.
QRSS 11QRSS 11, QRSS 20QRSS 20: Quasi-random signal source.
The bit length of QRSS 11 is 2047, the length of QRSS 20 is 1 048 575.

All 0'sAll 0's, All 1'sAll 1's: All bits are 0, all bits are 1.
Alternating 1:1Alternating 1:1: Bit pattern that 1 and 0 are repeated such as "010101..."
Alternating 1:3Alternating 1:3: Bit pattern that 1 and 000 are repeated such as
"100010001000..."
Alternating 1:7Alternating 1:7: Bit pattern that 1 and seven 0s are repeated such as
"1000000010000000..."
Alternating 3:24Alternating 3:24: A repeating 24-bit sequence that contains three ones, fifteen
consecutive zeros and 12.5% average ones density.
NormalNormal and InverseInverse are enabled except for User [32] bitUser [32] bit and User [2048] bitUser [2048] bit.

User pattern field is enabled if Pattern type is set to User [32] bitUser [32] bit or User [2084]User [2084]
bitbit. Touch the User patternUser pattern field and use the launched Pattern EditorPattern Editor dialog box
to define the user pattern. Depending on the selected pattern type, different
user pattern setup options will be available.
The length can be any length from 1 bit to 32 bits or from 1 bit to 2048 bits.
Unused time slotsUnused time slots
Touch the Unused time slotsUnused time slots field and use the launched dialog box to define
the unused time slots.
In the Unused time slotsUnused time slots dialog box, change the individual bits by touching on
the relevant bit keys - this will toggle the bit key's binary value from logic 1 to 0
or vice versa. Touch OkOk to accept the changes and close the dialog box.

Touch the Pattern time slotPattern time slot graphics and use the dialog box to select the
timeslots in which the Pattern will be inserted. Set and clear timeslots as
relevant.
