4.8 Combining Waveform Patterns by Combination File Edit Function
4-107
(3) Level [dB]
When Add Pattern is not selected:
Set the relative level ratio of each element to the set RF level value
of the MG3700A/MG3710A/MG3710E/MG3740A in dB units. For
example, when a combination file including an element for which
the level is set to –3 dB is selected, while the RF output power of
the MG3700A/MG3710A/MG3710E/MG3740A is set to 0 dBm, then
the RF output power of the
MG3700A/MG3710A/MG3710E/MG3740A when outputting the
element becomes –3 dBm. The setting range is from –80 to 0 dB,
with a resolution of 0.01 dB.
When Add Pattern is selected:
Set the level ratio for Add Pattern. The total power, of the Add
Pattern and the Element with the maximum level ratio set, is the
RF output power of the MG3700A/MG3710A/MG3710E/MG3740A.
For example, if a combination file is selected when the RF output
power of the MG3700A/MG3710A/MG3710E/MG3740A is set to 0
dBm, and the maximum set level ratio among the elements in the
combination file is +3 dB, then the total output power when
outputting this element becomes 0 dBm (Element power/Add
Pattern power = +3 dB)Although the setting range when Add
Pattern is selected is from –80 dB to +80 dB, the set values for all
elements must be within 80 dB. The setting resolution is 0.01 dB.
When AWGN is selected for Add Pattern, set the level by a power
ratio within the system bandwidth that is determined depending
on the communication system. In this event, it is required to set
necessary parameters such as the AWGN sampling rate for the
desired signal used by the element, in order to obtain correct
outputs. Refer to Section 4.9 “Generating AWGN Waveform
Pattern” for details.
(4) Repeat Count
Set the repetition count for each waveform pattern. The setting
range is from 0 to 65535. When 0 is input, this sets infinity. When
infinity is set, the same waveform pattern is repeatedly output until
any screen/remote operation is performed or Pattern Trigger is
input.
(5) Add Pattern (memory B pattern) selection
Select the waveform pattern to be used in memory B.
Note that a waveform pattern whose size exceeds the capacity of
memory B cannot be selected.
The waveform pattern selection method is the same as that shown in
“(2) Pattern” above.
