LEVEL DIAGRAM / 电平图

如要在 AF 部测量,则连接 AC 电平表。(天线输入:
- 53dBm , 1kHz FM , 3kHz DEV(宽))
如要在 RF 部测量,请使用 1000pF 耦合电容器。
没有本地电平。)
(图中显示了获得 12dB SINAD 所需的 SSG 输入值,
To make measurements in the AF section, connect
the AC level meter. (ANT input: -53dBm, 1kHz FM,
3kHz DEV (WIDE).)
In the RF section,use 1000pF coupling capacitor.
(The display shows the SSG input value required to
obtain 12dB SINAD without Local Level.)
AG 被设置成话筒输入得到 3kHz DEV 在 1kHz MOD
(宽)。
如要在 AF 部测量,则连接AC 电平表。
如要在 RF 部测量,请使用 1000pF耦合电容器。
AG is set to the MIC Input becomes 3kHz DEV.at
1kHz MOD.(WIDE)
To make measurements in the AF section, connect
the AC level meter.
In the RF section,use 1000pF coupling capacitor.
