将USB插⼊电脑，如果是RS232接⼝的该步可省略。由于已经安装了USB驱动，在设备管理器中会找到对应的COM⼝。

Insert the USB into the computer, if the interface is RS232 this step can be omitted.Because USB is already installed driver,in the device manager will find the corresponding COM port.

设备管理器中的COM⼝

记住该COM7的端⼝号，安装驱动后，不同的电脑COM⼝号会不同。点WINNWT软件的“Settings”----“Options”，选择对应的COM⼝号,再点“OK”。

The port number to remember the COM7, install the driver,different comp uter COMslogan will be different.WINNWT software \"Settings\

选择对应的COM⼝Select COM port

选择正确后，如果连机成功，会出现硬件的固件版本。否则连接或者设置有误。

Choose the correct, even if successful, will appear the hardware firmware version.Otherwise the connection or incorrectsettings.

选择端⼝正确后的提⽰

Logarithmic sweep frequency settings2.1，选择扫频模式

Select the sweep frequency mode

扫描模式选择

Select the sweep frequency mode2.2，频率等参数设置Set the frequency parameter

输⼊开始频率、结束频率、扫描点数，即可进⾏扫描。有2种扫描⽅式，⼀种是连续扫描，点后⼀直在扫描，直到点停⽌扫描；另⼀种是单独扫描，点下后，只扫描⼀次。不能再扫描过程中设置频率，扫描点数等参数，需要等扫描停⽌后才可设置。扫描延迟⽤于每个点输出频率后，进⾏多长延迟才进⾏功率测量。衰减器只能在扫描过程中进⾏设置，停⽌扫描后⽆法设置。Enter the start frequency, the end frequency, scanning number, can be scanned. There are 2 kinds of scanning mode, acontinuous scanning, point has been scannin g,until the point to stop scanning; another is the single scanning, point, onlyone sca nning. Frequency setting cannot be scanning, scanning number and other parameter s, to stop before setting.The scan delay for each point of the output frequency, are long latency for powe r measurement. Attenuator can be set only in

the scanning process, stop the scan c ould not be set.
