If the power is inside the allowed limits, but other RF parameters need to be modified, such
parameters are modified and an error about a settings conflict is set.
You can use the keyword “all” instead of
<signal name>
. However, in this case the
<orbit type name>
cannot be specified. The power you entered will be used for all sig
nal types for all constellations.
You can use the keyword “default” instead of
<power>
. The chosen
<signal name>
(and
optionally
<orbit type name>
) will be set to the default relative power offsets.
Examples
SEND:
SOUR:RELPOWer BDSB1,GEO,-123.2
SOURce:RELPOWer all,default
This command will reset the relative power offsets to their default values. The reference
power, however, WILL NOT be changed (to change the reference power level also, use
the command
SOUR:ABSPOW all, default
instead.)
6.3.3.8 SOURce:RELPOWer?
Function
Returns current relative power offset in dBm for the given signal type and orbit type (offset rel
ative to reference power).
Command Syntax
SOURce:RELPOWer? <signal name>,[<orbit type name>]
Example
SEND:
SOURce:RELPOWer? BDSB1,GEO
6.3.3.9 SOURce:EXTREF
Function
Specifies the reference clock source. If set to ON, the external reference clock signal is required
and used when scenarios are executed, or the signal generator is running.
