User Manual 1321.0950.02 ─ 07
This command is a query and therefore has no *RST value.
The suffix at CALCulate and LIMit are irrelevant for this command.
Parameters:
<return values>
Consists of two values, one for the lower and one for the upper
adjacent channel.
FAILed
Limit check failed.
PASSed
Limit check passed.
Example:
CALC:LIM:ACP:ACH:RES?
Queries the limit check results. The command would return, e.g.
FAILED,FAILED
Upper and lower alternate channels violate a
limit.
Usage:
Query only
CALCulate<1...2>:LIMit<1...2>:ACPower:ALTernate<1...11>[:RELative]
<RelativeLimit>
This command defines the relative limit of the alternate channels. The reference value
for the relative limit value is the measured channel power.
Note that the relative limit has no effect on the limit check if it is below the absolute limit
value (see
CALCulate<1...2>:LIMit<1...2>:ACPower:ALTernate<1...11>:
ABSolute
on page 452). This mechanism allows automatic checking of the absolute
basic values of adjacent-channel power as defined in mobile radio standards.
The suffix at CALCulate and LIMit are irrelevant for this command.
The suffix at ALTernate selects one of the 11 alternate channels.
Parameters:
<RelativeLimit>
Range:
-500 dB to 500 dB
Default unit: dB
Example:
CALC:LIM:ACP:ALT3 30
Defines a limit of 30 dB for the third alternate channel.
CALCulate<1...2>:LIMit<1...2>:ACPower:ALTernate<1...11>[:RELative]:STATe
<State>
This command turns the relative limit check for an alternate channels on and off.
You have to activate the general ACLR limit check before using this command with
CALCulate<1...2>:LIMit<1...2>:ACPower:STATe
on page 449 first.
The suffix at CALCulate and LIMit are irrelevant for this command.
The suffix at ALTernate selects one of the 11 alternate channels.
