Arb Commands

Dmodulation Subsystem–N5172B/82B with Option 431 ([:SOURce]:RADio:DMODulation:ARB)

:RAD:DMOD:ARB:NOIS:CBR 5

The preceding example sets the carrier bit rate to 5 Mbps.

Default

2.000000000 Mbps

Range

1 bps to 999 Mbps

Key Entry

Carrier Bit Rate

:NOISe:CBWidth

Supported

N5172B/82B with Option 431 and 403

[:SOURce]:RADio:DMODulation:ARB:NOISe:CBWidth <1Hz-125MHz>
[:SOURce]:RADio:DMODulation:ARB:NOISe:CBWidth?

This command selects the carrier bandwidth over which the AWGN (additive white gaussian noise) is
applied. The noise power will be integrated over the selected bandwidth for the purposes of
calculating C/N (carrier to noise ratio). The carrier bandwidth is typically the symbol rate. For more
information refer to

“:NOISe[:STATe]” on page 260

.

*RST

1.000000000 MHz

Range

1 Hz to 125 MHz

Key Entry

Carrier Bandwidth

:NOISe:CN

Supported

N5172B/82B with Option 431 and 403

[:SOURce]:RADio:DMODulation:ARB:NOISe:CN <-100dB - 100dB>
[:SOURce]:RADio:DMODulation:ARB:NOISe:CN?

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 the

“:NOISe:CBWidth”

command.

Example

:RAD:ARB:NOIS:CN 50DB

The preceding example sets the carrier to noise ratio to 50 dB.

*RST

+0.00000

Key Entry

Carrier to Noise Ratio

:NOISe:CNFormat

Supported

N5172B/82B with Option 431 and 403

[:SOURce]:RADio:DMODulation:ARB:NOISe:CNFormat CN|EBNO
[:SOURce]:RADio:DMODulation: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.
