简单操作说明如下

按键、旋钮及指示灯

电源开关 —— 按开关ON，所有电路即通上电。如果有外接交流电，仪器自动用交流电；否则，仪器转为使用直流电。在按下ON时，仪器就完成自动选择。
ON 指示灯 —— 按下ON时此灯亮。
DC 指示灯 —— 当仪器使用直流电时，此灯亮。
游标区按键(RF，AUD及DISP) —— 确定游标在CRT三个显示区中在哪个区有效。换区后，游标停留在上次在该区所在的位置。
游标位置按键(Up，Down，Left，Right，TAB) —— 此五键用于将游标上(Up)、下(Down)、左(Left)、右 (Right)或跳某位(TAB)地移动。
HELP —— 按下可显示用于当前屏幕的帮助信息。
MEM —— 可用于内存内容的预置。
数字键(0-9) —— 用于向测试仪输入数字信息。按某数字键，则游标所在处的数字被此键代表的数代替。仪器按新输入的数工作。如果所按的数字超出允许值，则该输入被忽略，原先显示的数字不变。
+／- —— 将所显示的某一值的符号反向。
ALT —— 按此键使某一键的另一种替代功能起作用，此时，屏幕上的信息行显示ALT，再按任何其他键后，屏幕上的ALT消失。
SPF —— 显示特别功能菜单。
PRT —— 把屏幕上显示的内容打印出来。
CAL —— 命令仪器进行自校准。
P1 —— 保留用作用户选择的特别功能。现用此键来从遥控工作方式转为本地工作方式。
软按键 —— 在屏幕的下部。软按键的功能随游标所在位置的变化而变化，从而对现行游标位置提供一个菜单以指示所有可能值或输入。
SQUELCH 静噪旋钮 —— 静噪控制。顺时针旋转会增加静噪打开时的信号电平门限值。
VOLUME 音量旋钮 —— 控制喇叭音量。
BRIGHT 亮度旋钮 —— 调节屏幕亮度。

CRT显示屏

这是点阵化了的9x11cm阴极射线管显示，显示内容包括数据、操作控制和指导性信息.显示方式包括数字、模拟及条状图。CRT在最后一次操作后的大约30分钟内会进入一种亮度减弱的节省状态。

插头座

RF IN/OUT —— 通过皮端口把射频输入信号接到机内的监视器，或输出机内产生的信号，在双工工作方式时，经由此端口提供组合的输入、出信号。皮端口包含射频率计的负载。在前面板上，这是唯一可以输入大功率射频的端口。
GEN OUT —— 此口与监视输入口相互独立，由它提供高电平的射频输出。请勿由此口输入大功率射频 !
ANT —— 灵敏监视接收机的输入端口，对测量空中电波很有用处。切勿由此口输入大功率射频 !
VERT/SINAD DIST/DVM COUNTER IN —— 此端口用作示波器Y轴、信纳比表、DVM（数字万用表）/计数器、畸变计、DVM以及频率计数器的输入端。
DEMOD OUT —— 在监视或双工工作方式下,恢复解调后的音频输出端口。
EXT MOD IN —— 外部调制信号输入端口。为精确显示电平，要求输入信号为固定的峰峰值一伏信号。
MIC —— 外接话筒端口。

注意 !!!

在GEN OUT和ANT的插座中装有射频保险丝以防过载，用一个板手把BNC型插府的前端部分拧下来，就可以更换保险丝。保险丝的零件号为GG-6530277C002。保险丝应剪成0.48正负0.02英寸(12.2正负0.05mm)长，其两端应修尖以适合安装。

插座

侧面板插座
RGB PORT (9 针) —— 用于外接CGA格式的彩色监视器。
RS-232 PORT (25 针) —— 用于外接打印机或其它控制器。
后面板插座
10MHz STD (BNC型插座) —— 由此端口接入或接出10MHz参考频率。输入阻抗为50欧。对输入电平的要求是70mV到1Vrms,输出电平大约为250uVrms.
