Syntax
:CALC:GSM
:RFTX:CORNer:RACH:LIMit[:FAIL]?
Parameters
There are no parameters.
Description
There is solely a query form of this command available.
Query
This command delivers eight boolean numbers, indicating whether the limits for the
eight corner positions of
random access
burst were violated by the bursts received or
not.
A
0
on a position means that there was no violation of the limits while a
1
indicates
that at least one measurement result did violate one of the two corresponding mea-
surement limits.
The eight boolean numbers correspond with the eight corner points set with the
:CALC:GSM:RFTX:CORN:RACH:POS
command as described above.
Example
:CALC:GSM:RFTX:CORN:RACH:LIM:FAIL?
String returned:
"0,1,0,0,0,0,0,0"
This string indicates that one of the two limits set for corner point 2 was violated.
Syntax
:CALCulate:GSM:RFTX:CORN:RACH:LIMit:STATe <PredefExp>
Parameters
PredefExp
is one of the following predefined expressions:
ON|OFF
. Default is
ON
.
Description
This command switches the check of the bursts against the limits at the corner points
either on or off for
random access
bursts.
Query
There is no query form of this command available.
Example
:CALC:GSM:RFTX:CORN:RACH:LIM:STAT OFF
Switches the limit check at the eight corner positions off.

:RFTX:CORNer:RACH:LIMit:UPPer[:DATA]
<real1>,<real2>,<real3>,<real4>,
<real5>,<real6>,<real7>,<real8>
Parameters
realx
are floating point real numbers.
The minimum value for all
realx
is
-150.0
, the maximum is
10.0
. The minimum
resolution possible for all
realx
is
0.01
. The default value is
4.0
for all
realx
.
Description
Sets the
upper
limits at the eight user-definable corner points for
random access
bursts. The single data values are dB relative to the power level during the active part
of the burst.
Query
There is no query form to this command.
