GENERAL DESCRIPTION
This chapter describes the use of the major function block- CENTER FREQUENCY FREQUENCY SPAN (or
START/STOP FREQUENCY), and REFERENCE LEVEL.
A FUNCTION is enabled by pressing the desired FUNCTION key Once enabled, the function, along with its
current data value, is displayed in the active graticule area of the CRT as well as outside the graticule border. To
change the value of the active function, use either the DATA knob, step keys, numeric keyboard, or a combination
of all three. The HOLD key above the DATA knob can be used to retain the present instrument state and prevent
any inadvertent entry of DATA. HOLD clears the active function area of the CRT as well as de-activates any
function.
