AWGN waveform pattern
Standard
■ AWGN waveform pattern:
The Additive White Gaussian Noise (AWGN) waveform pat-
terns listed in the table below are provided on the MG3700A
internal hard disk.
The signals for testing the receiver/transmitter of a terminal or
module can be output by selecting one of these AWGN
waveform patterns.

AWGN_3_84MHz_x2 >12 dB 7.68 3.01
Added with the W-CDMA UL signal to
perform a dynamic range test.
AWGN_3_84MHz_x1_5 >12 dB 5.76 1.76
Added with the W-CDMA UL signal to
perform a dynamic range test.
Added with the reverse signals of
AWGN_1.23MHz_x2 >12 dB 2.46 3.01 CDMA2000 or CDMA2000 1xEV-DO to
perform a dynamic range test.
Added with the reverse signals of
AWGN_1.23MHz_x1_5 >12 dB 3.69 1.76 CDMA2000 or CDMA2000 1xEV-DO to
perform a dynamic range test.

In-band power conversion ratio is the ratio of the system bandwidth of each communication system to the total power of the MG3700A output measured with a
power meter or another equivalent device.
