CALCulate Subsystem
6.30 Operating Manual 1302.6163.12 - 03
Example:
"CALC:LIM:ACP:ACH 30DB, 30DB"
'Sets the relative limit value in screen A for the power in the lower and upper
adjacent channel to 30 dB below the channel power.
"CALC:LIM:ACP:ACH:ABS -35DBM, -35DBM"
'Sets the absolute limit value in screen A for the power in the lower and upper
adjacent channel to -35 dB.
"CALC:LIM:ACP ON"
'Switches on globally the limit check for the channel/adjacent channel
measurement in screen A.
"CALC:LIM:ACP:ACH:STAT ON"
'Switches on the limit check for the adjacent channels in screen A.
"INIT;*WAI"
'Starts a new measurement and waits for the sweep end.
"CALC:LIM:ACP:ACH:RES?"
'Queries the limit check result in the adjacent channels in screen A.
Characteristics: *RST value: --
SCPI: device-specific
Mode: A
This command is a query and therefore has no *RST value.
CALCulate<1|2>:LIMit<1...8>:ACPower:ALTernate<1 to 11>[:RELative] 0 to 100dB, 0 to 100dB.
This command defines the limit for the alternate adjacent channels in the selected measurement
window for adjacent channel power measurements. The reference value for the relative limit value is
the measured channel power.
The numeric suffix after ALTernate<1 to 11> denotes the alternate channel. The numeric suffixes
<1...8> are irrelevant for this command.
It should be noted that the relative limit value has no effect on the limit check as soon as it is below the
absolute limit defined with
CALCulate:LIMit:ACPower:ALTernate<1 to 11>:ABSolute
. This
mechanism allows automatic checking of the absolute basic values of adjacent channel power as
defined in mobile radio standards.
Parameter: The first value is the limit for the lower and the upper alternate adjacent channel.
The second limit value is ignored but must be indicated for reasons of compatibility
with the FSE family.
Example:
"CALC:LIM:ACP:ALT2 30DB, 30DB"
'Sets the relative limit value in screen A for the power in the lower and upper
alternate adjacent channel to 30 dB below the channel power.
Characteristics: *RST value: 0DB
SCPI: device-specific
Mode: A
CALCulate<1|2>:LIMit<1...8>:ACPower:ALTernate<1 to 11>[:RELative]:STATe ON | OFF
This command activates the limit check for the alternate adjacent channels in the selected
measurement window for adjacent channel power measurements. Before the command, the limit
check must be activated using
CALCulate:LIMit:ACPower:STATe ON
.
The numeric suffix after ALTernate<1 to 11> denotes the alternate channel. The numeric suffixes
<1...8> are irrelevant for this command.
