Command Description
<sample_frequency_mhz> ::= float in MHz which must be one of the
specified values (see 0)
<target_frequency_mhz> ::= float in MHz which must be one of the
Specified values (see 0)
<clock_type> ::= “Internal” | “External”
<endianness> ::= “Big” | “Little”
<rf_on_off> ::= “on” | “off”
<timestamp>,
Level ,
<vehicle>,
<antenna>,
<channel>,
<reference_level>,
<level>
Adjust the level of the current RF IQ file being played
An example would be:
00:01:00, Level, 1, 1, 1, -130, 110
This would issue a command at 1 minute in to the scenario run for
vehicle 1, antenna 1, channel 1 and would adjust the RF signal level
of the interference signal to be at -20 dBm for the current
loaded/played IQ data.
Where:
<timestamp>
::= time in to run specified by: [d]
hh:mm:ss
<vehicle> ::= integer starting at 1
<antenna> ::= integer starting at 1
<channel> ::= integer starting at 1
<reference_level> ::= integer in dB i.e. -130
<level>
::= integer in dB
level above reference i.e. 110 would
set the
level to -20 dBm, -130 + 110 = -20
<timestamp>,
Delta Level ,
<vehicle>,
<antenna>,
<channel>,
<delta>
Adjust the level of the current RF IQ file being played
An example would be:
01:01:00, Delta Level, 1, 1, 1, -13
This would issue a command at 1 hour and 1 minute in to the
scenario run for vehicle 1, antenna 1, channel 1 and would adjust the
RF signal level. If the previous level was -20 dBm then the adjustment
of -13 would make the signal power output of the GSS7725 be -37
dBm for the current loaded/played IQ data.
Where:
<timestamp>
::= time in to run specified by: [d]
hh:mm:ss
<vehicle> ::= integer starting at 1
<antenna> ::= integer starting at 1
<channel> ::= integer starting at 1
<delta> ::= integer in dB i.e. -13
