NO. OF
ADJ CHAN
The NO. OF ADJ CHAN softkey activates the entry of the
number ±n of adjacent channels to be considered in the
adjacent-channel power measurement.
Numbers from 0 to 12 can be entered.
The following measurements are performed depending on the
number of the channels.
0
Only the channel powers are measured.
1 The channel powers and the power of the upper and lower
adjacent channel are measured.
2 The channel powers, the power of the upper and lower
adjacent channel and of the next higher and lower channel
(alternate channel 1) are measured.
3 The channel power, the power of the upper and lower
adjacent channel, the power of the next higher and lower
channel (alternate channel 1) and of the next but one
higher and lower adjacent channel (alternate channel 2)
are measured.
With higher numbers the procedure is expanded accordingly.
IEC/IEEE-bus command:
SENS:POW:ACH:ACP 1
This increased number of adjacent channels is realized all for
the relevant settings like:

NO. OF
TX CHAN
The NO. OF TX CHAN softkey enables the entry of the number
of carrier signals to be considered in channel and adjacent-
channel power measurements.
Numbers from 1 to 12 can be entered.
The softkey is available only for multicarrier ACP
measurements.
