SME Digital Modulation
1038.6002.02 2.111 E-13
PHASE
Selection of which phase (A to D) the message is to be transmitted. Since
each frame lasts 1.875 sec independent of the modulation and more data
can be transmitted at bit rates higher than 1600 bps, several independent
channels ("phases") are bit-multiplexed. With 1600 bps, the message is
transmitted for every setting in phase A. With 3200 bps, the message is
transmitted in phase A if A and B are set, and transmitted in phase C if C
and D are set. With 6400 bps, the message is transmitted in all the four
phases depending on the relevant setting. Each pager is set to one phase.
The phase can be calculated from the CAPCODE of a pager as shown
below:
Phase = (Integer(CAPCODE/4)) modulo 4, with 0=A, 1=B, etc.
IEC-bus command: :SOUR:FLEX:PHAS A
CATEGORY...
Selection of message category for all frames where FRAME CONTENT
contains the entry ’X’ or ’x’. For all other values of FRAME-CONTENTS,
this setting is ignored.
TONE tone-only message
NUMERIC numeric message,
with
≤
3 figures = short message
SNUMERIC special numeric message
ALPHANUM alphanumeric message
SECURE secure alphanumeric message
BIN binary message
IEC-bus command: :SOUR:FLEX:MESS:CAT TONE
REPEATS
Entry of the number of calls following the first call according to FLEX-TD.
For the value 0 (no repeat), normal FLEX frames are transmitted,
whereas subframes according to FLEX-TD are used with other values.
The repeat calls are transmitted at the frame interval defined by the
SYSTEM COLLAPSE VALUE. A frame may contain a new message and
repetitions of previous messages.
Notes: – Since the SME transmits the messages always completely in
a (sub-)frame, the maximum length of the SME-generated
message decreases with increasing values.
– The SME generates a complete cycle which is repeated
continuously. Repetitions which are contained in the
subsequent cycle are already transmitted in the current cycle,
i.e., they might be transmitted prior to transmitting the
original.
IEC-bus command: :SOUR:FLEX:MESS:REP 0...3
TONE NUMBER
Input value of the tone which is transmitted during category TONE.
8 tones are available.
IEC-bus command: :SOUR:FLEX:MESS:TONE 0
NUMERIC/SNUMERIC
MESSAGE...
Opens a window to enter the character string for a numeric or special
numeric message. SME provides a maximum of 41 characters. In addition
to the 10 figures "0" to "9" other characters such as square brackets right
and left "[", "]", upper case letter "U", hyphen "-" and blank space " " can
be used.
IEC-bus command: :SOUR:FLEX:MESS:NUM "12-17"
