MG3700A

Useful Standard Functions

Waveform Combining Function

The MG3700A has two built-in arbitrary waveform memories, each

of which can hold one waveform pattern.

The MG3700A can output a signal from either memory, as well as

combine and output both signals simultaneously.

When measuring receiver characteristics, such as Adjacent

Channel Selectivity (ACS) or Blocking characteristics, one

MG3700A can output both the Wanted Signal and the Interfering

Signal or the Wanted Signal with AWGN.

Digital signal processing ensures excellent level accuracy.

Combination file

The Combination function makes the work of waveform addition

even easier. It uses a file in which various parameters, such as the

pattern file for the two waveform memories, the output level ratio,

and the offset frequency, are pre-defined.

When selected, the values for these parameters are automatically

set in the MG3700A.

• Processing required waveform + interference waveform

• Set required waveform in memory A.

• Set interference waveform in memory B.

• Set level of required waveform.

• Set level of interference waveform.

• Set offset frequency of required and interference waveforms.

• Processing W-CDMA control CH + Data CH

• Set Control CH in memory A.

• Set Data CH in memory B.

• Set level of Control CH.

• Set level of Data CH.

Steps without Combination function
