SME Digital Modulation
1038.6002.02 2.125 E-13
RECALCULATE Ð
Triggers recalculation of the generated ReFLEX25 telegram and -
with AUTO ADAPTATION set to ON - an update of the RF
frequency. The execution of RECALCULATE is required when a
setting is changed that influences the telegram. This includes all
parameters except for FRAME CONTENTS, AUTO
ADAPTATION, MODE and CLOCK SOURCE. The same result
can be obtained by briefly switching ReFLEX25 off and on again.
IEC-bus command: SOUR:REFL25:STAT OFF; STAT ON
MODE
Selection of the output mode. The contents of the individual
frames is mainly determined by FRAME CONTENTS. However,
MODE also performs an interpretation in this case.
ALWAYS The SME starts with the generation of the
ReFLEX25 signal immediately after switching on
of ReFLEX25. The frames are sent in the way
they have been specified under FRAME
CONTENTS.
IEC-bus command: :TRIG:DM:SOUR AUTO
SINGLE The SME starts with the generation of the
ReFLEX25 signal immediately after switching on
of ReFLEX25. All ALPH, NUM and TONE frames
are replaced by IDLE frames. By selecting
EXECUTE SINGLE,
one
ALPH, NUM or TONE
frame (as specified in FRAME CONTENTS) is
transmitted; all further ALPH, NUM and TONE
frames are again replaced by IDLE frames until
EXECUTE SINGLE is triggered again.
IEC-bus command:
:TRIG:DM:SOUR SING;
:SOUR:REFL25:TACT MESS
EXT-SINGLE The SME starts with the generation of the
ReFLEX25 signal immediately after switching on
of ReFLEX25. EXT-SINGLE behaves like
SINGLE, however, instead of EXECUTE
SINGLE, a trigger signal is required at the trigger
input connector.
IEC-bus command:
:TRIG:DM:SOUR EXT;
:SOUR:REFL25:TACT MESS
EXTTRIG The SME only starts with the generation of the
ReFLEX25 signal after recognition of a trigger
pulse at the trigger input connector. After
recognition of this signal, exactly one cycle (up to
128 frames) is output. The frames are output in
the way they have been specified in FRAME
CONTENTS. After execution of the cycle, the
SME waits for a new trigger pulse.
IEC-bus command:
:TRIG:DM:SOUR EXT;
:SOUR:REFL25:TACT ONCE
