SOURce subsystem - Transmitter SONET OVERHEAD SETUP
:SOURce:DATA:TELecom:SONet:TRIButary:POVerhead:J2:PATTern?
Returns :
:SOURce:DATA:TELecom:SONet:TRIButary:POVerhead:J2 <string>
Sets the user defined pattern that is to be transmitted in the J2 byte of the VT-6, VT-
2 or VT-1.5 path overhead. The pattern should be 15 characters long. If less than 15
characters are input, the instrument will pad with the required number of NULL
characters and a frame marker byte with CRC7 is added to the string. The pattern
repeats every 16 characters and is transmitted byte by byte in subsequent frames.
The corresponding query returns the value of the user defined pattern as a string, as
defined above. If the string contains any non printing characters, ~ is substituted.
:SOURce:DATA:TELecom:SONet:TRIButary:POVerhead:J2?
Returns :
:SOURce:DATA:TELecom:SONet:TRIButary:POVerhead:J2:HEXadecimal?
Returns :
Returns a 16 byte block of data. Each byte represents the hexadecimal value of an
ASCII character of VT-6, VT-2 or VT-1.5 byte J2 in the range "00" to "FF". The 15
hexadecimal numbers are preceded by the header "#215".
:SOURce:DATA:TELecom:SONet:TRIButary:POVerhead:J2:FIXed <string>
<string> =
Sets the user defined fixed byte that is to be transmitted in the J2 byte of the VT-6,
VT-2 or VT-1.5 path overhead. The value is a binary string.
The corresponding query returns the value of the user defined fixed byte as a binary
string, as defined above.
