1. FREQUENCY, SPAN, and AMPLITUDE are the fundamental
functions for most measurements. The HOLD key freezes the active
function and holds it at the current value until a function key is
pressed.
2. INSTRUMENT STATE functions affect the state of the entire
spectrum analyzer, not just the state of a single function.
3. MARKER functions read out frequencies and amplitudes on the
spectrum analyzer trace, let you make relative measurements,
automatically locate the signal of highest amplitude on a trace, and
tune the spectrum analyzer to track a signal automatically.
4. CONTROL functions allow you to adjust the resolution and video
bandwidths, the sweep time, the display, and other functions that
control spectrum analyzer measurement capabilities.
5. DATA keys, STEP keys, and the knob allow you to change the
numeric value of the active function. Use the data keys to enter an
exact value or to move quickly from one value to another. The step
keys vary a value in predefined increments or, for some functions, in
increments that you choose. The knob allows you to fine-tune most
numeric values.
