Response to Query
Tx Power Level
TPL=
5 bytes
Command or Query.
Tx Output power level in the form sxx.x, where:
s=sign ( + / - )
xx.x = Tx Output power level, +05.0 and –20.0 dBm.
L-Band: -25.0 to –05.0 dBm
70/140 MHz: -20.0 to +00.0 dBm
Note:
Beyond –20 dBm is beyond the specification.
Example:
TPL = -13.4
TPL=
TPL?
TPL*
TPL#
TPL?
TPL=sxx.x
Test Pattern
TPT=
1 byte
Command or Query.
Set Test Pattern in the form x, where:
0=Off
1=2047
2=2^23-1
Example:
TPT=1 (2047)
TPT=
TPT?
TPT *
TPT #
TPT? TPT=x
Transmit &
Receive
Configuration
TRC=
69 bytes
Command or Query.
Global configuration, in the form:
aaa.aaaabcc.ccccccdefghhhhhhiii.ijkllll.llllmnn.nnnnnnopqrsssssstuvv, where:
aaaa.aaaa = Tx Frequency (in MHz) same as TFQ
b = Tx Mode
same as TMM
cc.cccccc = Tx Symbol Rate
same as TSR
d = Tx FEC Type
same as TFT **
e = Tx Modulation type
same as TMD
f = Tx FEC Rate
same as TCR
g = Tx Spectrum Inversion
same as TSI
hhhhhh = Tx Gold Code Sequence
same as TGS
iii.i = Tx Power Level
same as TPL
j = Tx Carrier State
same as TXO
k = Tx Alpha Roll-off
same as TAR
llll.llll = Rx Frequency (in MHz) same as RFQ
m = Rx Mode
same as RMM
nn.nnnnnn = Rx Symbol Rate
same as RSR
o = Rx FEC Type
same as RFT **
p = Rx Modulation type
same as RMD
q = Rx FEC Rate
same as RCR
x = spare
ssssss = Rx Gold Code Sequence
same as RGS
t = Rx Alpha Roll-off
same as RAR
u = Unit test Mode
same as TST**
vv = Unit Alarm Mask
same as MSK
** Read-only
TRC=

sssssstuvv
Returns current transmit and
receive configuration.
Notes:
1. Unit returns ‘x’s for Rx
parameters if unit is modulator
only.
2. Unit returns ‘x’s for Tx
parameters if unit is
demodulator only.
3. If Rx is in DVB-S2 mode, the
Rx Modulation Type and Rx
FEC Rate is ignored
because these are
automatically detected.
