Two different Spectrum Analyzer Measurement Guides describe the Spectrum Analyzer operation. Check the SPA firmware version number, then consult 
Measurement Guidesto find the correct Measurement guide for your instrument. 
 
      The Spectrum Master menu‑driven interface is easy to use and requires little training. The 5 Main Menu keys are located below the measurement display. These 5 keys are used to list function‑specific menus in the active menu (submenu labels). These Main Menu keys vary in function based on the selected mode of operation (
Shift, Mode (9)). Refer to 
“Mode Selector Menu” on page 1‑6 for more information on changing the instrument mode. 
Table 1‑1 lists the Main Menu Key labels for each mode of instrument operation. 
 
      The 8 submenu keys are located to the right of the measurement display. They change function depending upon the current mode and current menu selection. The current submenu title is shown at the top of the active function block (submenu keys labels). Refer to 
Figure 1‑2 on page 1‑3.
