Open the PatternPattern drop-down menu to select the relevant pattern.
FOXFOX: ASCII code bit sequence of "THE QUICK BROWN FOX JUMPS OVER
THE LAZY DOG".
55555555: Repetition of "0101010101010101".
PRBS9PRBS9 to PRBS31PRBS31: Pseudo-random bit sequence. For PRBS9, its bit length is
511 (=2
9
-1).
HF TESTHF TEST: High frequency test pattern. (Defined in IEEE802.3 Annex 48A)
CRPATCRPAT: Continuous random test pattern. (Defined in IEEE802.3 Annex 48A)
JTPATJTPAT: Jitter tolerance test pattern.
SPATSPAT: Supply noise pattern.
User 32 bitUser 32 bit: Repetition of the user defined 32 bits.
If you select the User 32 bitUser 32 bit pattern, a button appears with which you can open
the Pattern EditorPattern Editor dialog box.
Selecting Cross pattern at successive framesCross pattern at successive frames sets the payload in Ethernet
frames as successive payload pattern through multiple frames.
Cross pattern at successive framesCross pattern at successive frames is available for BERT application only.
Following is the explanation of an example when:
Payload pattern is set to PRBS15PRBS15.
In this case, the pattern length is 32767 bit (≈ 4096 byte).
Frame size is set in Stream on
Test
setup screen so that the payload
length will be 1024 byte.
When the check box
is not
selected, Top of 1024 bytes in the payload pattern
are set to the payload in Ethernet frames.
