Hardkey and Softkey Reference
Mode - TETRA
•
Modulation:
π
/4DQPSK
- Indicates that
π
/4DQPSK modulation is being
internally generated.
•
TETRA: STANDARD
- Indicates that the structure of the TETRA transmission follows
the standard as defined by the TETRA protocol. This field changes to
TETRA:
MODIFIED
under the following circumstances:
•
filter is NYQ
•
filter alpha is changed
•
bit rate is changed
•
burst shape is changed
•
phase polarity is set to invert
•
Bit/Symbol: 2
- Indicates that 2 bits per symbol are required according to the
TETRA standard.
•
Bit Rate: 36.000kbps
- The bit rate is set according to the TETRA standard.
This can be changed in the Bit Rate menu. A * next to the value indicates that it differs
from the standard.
•
Filter: RNYQ (
α
=0.35)EVM
- Indicates that root Nyquist filter (root raised
cosine) is selected, with an alpha of 0.35, and the filter is set for optimizing error vector
magnitude. A * next to the alpha value indicates that it differs from the standard. If you
select optimization for adjacent channel power,
EVM
toggles to
ACP
. This field changes
to
Filter: NYQ(
α
=0.35)
if you select the Nyquist filter (raised cosine).
•
Data: PN9
- Indicates that a PN9 sequence has been selected for transmitting without
framing. In this example, the text in this field is grey, indicating an inactive function
(framed mode is on). Other selections allowed include PN15, fixed 4-bit patterns, fixed
patterns of ones and zeroes, user files, or external data.
•
Repeat: Cont
- Indicates that the data pattern repeat is set to continuous mode. If
you select single mode, this field changes to
Repeat: Single
.
•
Phase Pol: Normal
- Indicates the direction of rotation of the phase modulation
vector. If you select inverted mode, this field changes to
Phase Pol: Invert
.
•
The visual representation of the TETRA timeslot pattern shows, in this case, that
timeslot 1 is on and configured as an uplink normal timeslot. Timeslots 2, 3, and 4 are
off and configured as uplink normal timeslots. The timeslot pattern is displayed only
when
Data Format Pattern Framed
is set to
Framed
.
To configure the timeslots, press the
Configure Timeslot
softkey. The
Configure Timeslot
softkey is activated when you select
Data Format Framed
and is
inactivated when you select
Data Format Pattern
.
Softkey Location: Press
