Parameters
Packet Type - Presents a menu of Packet types.
Packet Length - Enter a value in bytes.
L_CH=01, L_CH=10, L_CH=11 - Defines payload header L_CH value and type of
payload to be sent. Data payload of L_CH=11b is restricted to a pseudo-random value that
does not match any existing LMP PDU.
Duration - Set time in msec.
Time Length - Enter a value in msec.
Error Type - Presents a menu of error types.
Error Mask - Defines error distribution. Insert an error into a payload or in to header. This
option is context sensitive and depends on the type of error selected
Example:
1. error_type = FEC 1/3 header, and error_mask=8000, 1-bit error is inserted into the header
and the error bit will be the first bit in header.
2. error_type = FEC 2/3 payload, and error_mask=0c00, 2-bit error is inserted into the
payload and the error bits will be the 5th and 6th bits in payload.
When running base band tests, make sure the mask starts from left (no leading zeros) since
the FW will apply error mask to every bit depends on how many time the test will run.
PBRS - If checked, will generate random data.
Data Pattern - Define a pattern to be matched.
Tx Jitter - Random jitter range from -9.5 to 9.5. Check '+0.5us' box is 0.5 jitter as needed.
