SME Digital Modulation
1038.6002.02 2.113 E-13
MAIL DROP FLAG
Switch on/off of MAIL DROP flag
ON The transmitted message is marked as "volatile". Thus, it is not
filed in the normal message memory of the pager but in a
special memory location and is not subject to normal numbering.
The message overwrites the previous "volatile" one.
OFF The message is not marked.
IEC-bus command: :SOUR:FLEX:MESS:MDR OFF
----BIT ERRORS---
The SME allows for providing a 32-bit-word of the transferred message
with bit errors for test purposes. The parameters of this section specify the
erroneous bits and their positions.
ERROR BIT MASK
Entry of the erroneous bits in a 32-bit field. The transmitted decimal
number (0...4294967295) is converted internally into a 32-bit binary
number and thus defines the 32 bits. These bits are XORed with the word
of the message which is to be falsified and thus determine which bits of
this word are to be transmitted correctly or incorrectly.
Note: XORing precedes block interleaving (see FLEX standard)! It is
carried out in all phases of all message frames.
IEC-bus command: :SOUR:FLEX:ERR:MASK 0
POSITION OF
ERRONEOUS WORD
Entry value for the position of the word to be falsified. The words are
numbered from block 0, word 0 to block 10, word 7 of a frame. The sync
part and the frame information word cannot be falsified. The falsification
precedes block interleaving in all transmitted phases.
IEC-bus command: :SOUR:FLEX:ERR:WORD 0
--- MESSAGE
GENERATION ---
The parameters of this section determine which types of data (FLEX
useful data, FLEX filler data, simulated data of other paging systems or
emergency resynchronization) are sent at what time.
This can individually be determined for every frame of a cycle with the
setting then being valid for
all
cycles. The cycle and frame numbers are
generated and sent in compliance with standard for a period of one hour.
START IN CYCLE
Input value of number of cycle with which the message is started.
Valid values are 1 to 14.
IEC-bus command: :SOUR:FLEX:CYCL 0
START IN FRAME
Input value of the number of the frame in the cycle with which the
message is started. Valid values are 1 to 127.
IEC-bus command: :SOUR:FLEX:FRAM 0
