Agilent X-Series Signal Generators SCPI Command Reference 317
Arb Commands
Multitone Subsystem–N5172B/82B ([:SOURce]:RADio:MTONe:ARB)
This command sets the carrier to noise ratio in dB. The carrier power is defined as the total
modulated signal power without noise power added. The noise power is applied over the specified
bandwidth of the carrier signal. For more information, refer to :NOISe:CBWidth.
Example
:RAD:ARB:NOIS:CN 50DB
The preceding example sets the carrier to noise ratio to 50 dB.

[:SOURce]:RADio:MTONe:ARB:NOISe:CNFormat CN|EBNO
[:SOURce]:RADio:MTONe:ARB:NOISe:CNFormat?
This command selects either the Carrier to Noise Ratio (C/N) or energy per bit over noise power
density at the receiver (E
b
/N
0
) as the variable controlling the ratio of carrier power to noise power in
the carrier bandwidth.
Example
:RAD:MTON:ARB:NOIS:CNF EBNO
The preceding example sets the carrier to noise ratio format to E
b
N
o
.

:NOISe:EBNO

[:SOURce]:RADio:MTONE:ARB:NOISe:EBNO <ebno in dB>
[:SOURce]:RADio:MTONE:ARB:NOISe:EBNO?
This command allows the C/N to be set using the E
b
/N
0
(energy per bit over noise power density at
the receiver) form. This requires that the carrier bit rate ( :NOISe:CBRate on page 316) be set
properly. The range of E
b
/N
0
is limited to the range that is equivalent to –100 to 100 dB of C/N. This
value is only effective when E
b
/N
0
has been enabled by the :NOISe:CNFormat command.
The query returns the value of E

0
.
