</span><br />
<span style="background-color:#FFE500;"><strong>仪器使用规程</strong></span><br />
<span style="">&nbsp;仪器的供电:</span><br />
<span style="">1、使用3端电源线,检查确认地线接地.&nbsp;</span><br />
<span style="">2 、检查电压在仪器允许范围之内. 电压不稳时,应使用稳压器</span><br />
<span style="">防静电保护:</span><br />
<span style="">1 、仪器应摆放在防静电工作台上.</span><br />
<span style="">2 、操作人员穿戴好防静电服, 防静电手环等.</span><br />
<span style="">3 、禁止用手直接接触射频端口的内芯.</span><br />
<span style="">使用环境:</span><br />
<span style="">1、 环境温度保持在20~30摄氏度,环境湿度应小于80%,&nbsp;</span><br />
<span style="">2、 仪器使用时应避免搬动,振动可能损坏仪器.</span><br />
<span style="">3、 保持仪器通风良好通风孔应距离其它物体20厘米以上.</span><br />
<span style="">仪器使用注意事项:</span><br />
<span style="">1 、禁止输入功率**过端口大允许输入功率,否则应加衰减器.</span><br />
<span style="">2 、禁止在射频端口上输入直流电压.建议加直流隔离器 (DC Block).</span><br />
<span style="">3 、GPIB线不可以热插拔</span><br />
<span style="">端口保养:</span><br />
<span style="">1 、端口应轻柔,缓慢的旋紧, 禁止用普通扳手拧端口.</span><br />
<span style="">2 、禁止将50欧姆转接头连接到75欧姆端口上,否则会发生物理损坏.</span><br />
