选择Ymax=10,Ymin=-30 Select Ymax=10, Ymin=-30
2.6带宽显示
bandwidth display
测量出来的曲线，可直接显示3dB带宽、Q值、6dB带宽、60dB带宽和矩形系数 The measured curve, can directly display the 3dB bandwidth, Q value, 6dB bandwidth, 60dB bandwidth and rectangular coefficient
带宽选择 Bandwidth selection
3dB/Q打勾后，软件中会显示出测量的曲线3dB带宽和Q值
3dB/Q tick, the software will display the measured curve 3dB bandwidth and Q value
26
测量的曲线 The measured curve
显示的3dB带宽，Q值和相关参数
Display 3dB bandwidth, Q value and related parameters
6dB带宽,60dB,带宽，矩形系数也是同样道理
Markerlines用于在图形区显示带宽相关的虚线，更易识别带宽参数。 Inverse用于陷波器测量。
6dB bandwidth, 60dB, bandwidth, is similarly rectangular coefficient
27
Markerlines is used to display the dotted line bandwidth related in the graphics area, more recognition bandwidth parameter.
Inverse is used to trap measurement.
2.7，多曲线显示
Multi curve display
测量完毕后，可通过图形管理区存储，显示曲线。
先点Graphae-Manager选择图形管理存储区。通过 Get获得当前屏幕曲线；Actibe channel打勾，选择相应的通道；Show Graph 打勾，显示当前的曲线
After measurement, by storing graphic management area, shows the curve. The first point of Graphae-Manager graphics memory area management.Get the current screen curve by Get; Actibe channel tick, select the corresponding channel; Show Graph tick, displays the current curve
图形管理区 Graph manage
28
图形区管理区选择了3个图形
Management pattern area selected 3 graph
图形区显示了3条曲线
Diagram shows 3 Curves
3，线性扫描设置
Linear scan settings
线性探头的灵敏度远比对数探头要低，动态范围也不大。
The sensitivity of linear probe is far lower than the logarithmic probe,dynamic range is
29
small.
3.1，如何选择线形探头 Select line detetor
点 “Sweep” ---“Select Channel 1” Click “Sweep” ---“Select Channel 1”
选择通道1 Select channel 1
选择“defsonde1lin.hfm”文件，即选择线性扫描方式。如果选择defsonde1.hfm则是选择对数扫描方式
Select the \selection of log scan mode
