849Operating Manual 1176.7510.02 ─ 09
The command is available only for multicarrier channel and adjacent-channel power
measurements with span > 0 ( CALCulate<n>:MARKer<m>:FUNCtion:POWer:
SELect on page 703).
Parameters:
<ChannelNumber> 1 to 18
*RST: 1
Example:
POW:ACH:REF:TXCH:MAN 3
Transmission channel 3 is used as a reference channel.
Manual operation: See "ACLR Reference" on page 327
[SENSe:]POWer:ACHannel:SPACing[:ACHannel]
<Spacing>
This command defines the spacing between the carrier signal and the adjacent chan-
nel (ADJ). The modification of the adjacent-channel spacing (ADJ) causes a change in
all higher adjacent-channel spacings (ALT1, ALT2, ...): they are all multiplied by the
same factor (new spacing value/old spacing value).
Parameters:
<Spacing> 100 Hz to 20 GHz
*RST: 14 kHz
Example:
POW:ACH:SPAC 33kHz
Sets the spacing between the carrier signal and the adjacent
channel to 33 kHz, the alternate adjacent channel 1 to 66 kHz,
the alternate adjacent channel 2 to 99 kHz, and so on.
Manual operation: See "Spacing" on page 328
[SENSe:]POWer:ACHannel:SPACing:ALTernate<channel> <Spacing>
This command defines the spacing between the alternate adjacent channels and the
TX channel (ALT1, ALT2, ...). A modification of a higher adjacent-channel spacing cau-
ses a change by the same factor (new spacing value/old spacing value) in all higher
adjacent-channel spacings, while the lower adjacent-channel spacings remain
unchanged.

the alternate adjacent channel
Parameters:
<Spacing> 100 Hz to 20 GHz
*RST: 40 kHz (ALT1), 60 kHz (ALT2), 80 kHz (ALT3), ...
Example:
POW:ACH:SPAC:ALT1 100 kHz
Sets the spacing between TX channel and alternate adjacent
channel 1 (ALT1) from 40 kHz to 100 kHz. In consequence, the
spacing between the TX channel and all higher alternate adja-
cent channels is increased by the factor 100/40 = 2.5: ALT2 =
150 kHz, ALT3 = 200 kHz, ALT4 = 250 kHz.
