簡單操作說明如下

按鍵、旋鈕及指示燈

  1. 電源開關 —— 按開關ON，所有電路即通上電。如果有外接交流電，儀器自動用交流電；否則，儀器轉為使用直流電。在按下ON時，儀器就完成自動選擇。
  2. ON 指示燈 —— 按下ON時此燈亮。
  3. DC 指示燈 —— 當儀器使用直流電時，此燈亮。
  4. 游標區按鍵(RF，AUD及DISP) —— 確定游標在CRT三個顯示區中在哪個區有效。換區后，游標停留在上次在該區所在的位置。
  5. 游標位置按鍵(Up，Down，Left，Right，TAB) —— 此五鍵用于將游標上(Up)、下(Down)、左(Left)、右 (Right)或跳某位(TAB)地移動。
  6. HELP —— 按下可顯示用于當前屏幕的幫助信息。
  7. MEM —— 可用于內存內容的預置。
  8. 數字鍵(0-9) —— 用于向測試儀輸入數字信息。按某數字鍵，則游標所在處的數字被此鍵代表的數代替。儀器按新輸入的數工作。如果所按的數字超出允許值，則該輸入被忽略，原先顯示的數字不變。
  9. +／-  —— 將所顯示的某一值的符號反向。
  10. ALT —— 按此鍵使某一鍵的另一種替代功能起作用，此時，屏幕上的信息行顯示ALT，再按任何其他鍵后，屏幕上的ALT消失。
  11. SPF —— 顯示特別功能菜單。
  12. PRT —— 把屏幕上顯示的內容打印出來。
  13. CAL —— 命令儀器進行自校準。
  14. P1 —— 保留用作用戶選擇的特別功能�，F用此鍵來從遙控工作方式轉為本地工作方式。
  15. 軟按鍵 —— 在屏幕的下部。軟按鍵的功能隨游標所在位置的變化而變化，從而對現行游標位置提供一個菜單以指示所有可能值或輸入。
  16. SQUELCH 靜噪旋鈕 —— 靜噪控制。順時針旋轉會增加靜噪打開時的信號電平門限值。
  17. VOLUME 音量旋鈕 —— 控制喇叭音量。
  18. BRIGHT 亮度旋鈕 —— 調節屏幕亮度。

CRT顯示屏

這是點陣化了的9x11cm陰極射線管顯示，顯示內容包括數據、操作控制和指導性信息.顯示方式包括數字、模擬及條狀圖。CRT在最后一次操作后的大約30分鐘內會進入一種亮度減弱的節省狀態。

插頭座

  • RF IN/OUT —— 通過皮端口把射頻輸入信號接到機內的監視器，或輸出機內產生的信號，在雙工工作方式時，經由此端口提供組合的輸入、出信號。皮端口包含射頻率計的負載。在前面板上，這是唯一可以輸入大功率射頻的端口。
  • GEN OUT —— 此口與監視輸入口相互獨立，由它提供高電平的射頻輸出。請勿由此口輸入大功率射頻 !
  • ANT —— 靈敏監視接收機的輸入端口，對測量空中電波很有用處。切勿由此口輸入大功率射頻 !
  • VERT/SINAD DIST/DVM COUNTER IN —— 此端口用作示波器Y軸、信納比表、DVM（數字萬用表）/計數器、畸變計、DVM以及頻率計數器的輸 入端。
  • DEMOD OUT —— 在監視或雙工工作方式下,恢復解調后的音頻輸出端口。
  • EXT MOD IN —— 外部調制信號輸入端口。為精確顯示電平，要求輸入信號為固定的峰峰值一伏信號。
  • MIC —— 外接話筒端口。

注 意 !!!

在GEN OUT和ANT的插座中裝有射頻保險絲以防過載，用一個板手把BNC型插府的前端部分擰下來，就可以更換保險絲。保險絲的零件號為GG-6530277C002。保險絲應剪成0.48正負0.02英寸(12.2正負0.05mm)長，其兩端應修尖以適合安裝。

插座

  • 側面板插座
    RGB PORT (9 針) —— 用于外接CGA格式的彩色監視器。
    RS-232 PORT (25 針) —— 用于外接打印機或其它控制器。
  • 后面板插座
    10MHz STD (BNC型插座) —— 由此端口接入或接出10MHz參考頻率。輸入阻抗為50歐。對輸入電平的要求是70mV到1Vrms,輸出電平大約為250uVrms.
