Relative Limit ← Limits ← Channel Setup ← CP/ACLR Settings ← Ch Power
ACLR
Defines a limit relative to the carrier signal.

CALC:LIM:ACP:<adjacent-channel> 0dBc,0dBc
CALC:LIM:ACP:<adjacent-channel>:STAT ON
Absolute Limit ← Limits ← Channel Setup ← CP/ACLR Settings ← Ch Power
ACLR
Defines an absolute limit.

Check ← Limits ← Channel Setup ← CP/ACLR Settings ← Ch Power ACLR
Activate or deactivate the limit to be considered during a limit check. The check of both
limit values can be activated independently.
Chan Pwr/Hz ← CP/ACLR Settings ← Ch Power ACLR
If deactivated, the channel power is displayed in dBm. If activated, the channel power
density is displayed instead. Thus, the absolute unit of the channel power is switched
from dBm to dBm/Hz. The channel power density in dBm/Hz corresponds to the power
inside a bandwidth of 1 Hz and is calculated as follows:
"channel power density = channel power – log
10
(channel bandwidth)"
By means of this function it is possible e.g. to measure the signal/noise power density
or use the additional functions "ACLR (Abs/Rel)" on page 243 and "ACLR Reference"
on page 239 to obtain the signal to noise ratio.
Remote command:
CALCulate<n>:MARKer<m>:FUNCtion:POWer:RESult:PHZ on page 746
Power Mode ← CP/ACLR Settings ← Ch Power ACLR
Opens a submenu to select the power mode.
Clear/Write ← Power Mode ← CP/ACLR Settings ← Ch Power ACLR
If this mode is activated, the channel power and the adjacent channel powers are cal-
culated directly from the current trace (default mode).
