Making a Basic Measurement
This section provides information on basic analyzer operation. For more
information on making measurements, see the appropriate
measurement chapter.
This section is divided into the following sections:
“Entering Data” on page 71
“Using Menu Keys” on page 71
“Presetting the Spectrum Analyzer” on page 73
“Creating a User Preset and Power-Up State” on page 73
“Viewing a Signal” on page 74
CAUTION Ensure that the total power of all signals at the analyzer input does not
exceed +33 dBm (2 watts).
Basic Assumption
The material in this chapter is presented with the assumption that you
understand the front and rear panel layout, and display annotations of
your analyzer. If you do not, refer to the Measurement Guide “Front and
Rear Panel Features” on page 51.
Entering Data
When setting measurement parameters, there are several ways to enter
or modify the value of the active function:
Using Menu Keys
Menu Keys (which appear along the right side of the display) provide
access to many analyzer functions. Here are examples of menu key
types:
Knob Increments or decrements the current value.
Arrow Keys Increments or decrements the current value.
Numeric
Keypad
Enters a specific value. Then press the desired terminator
(either a unit menu key, or the Enter key).
Unit Menu Keys Terminate a value that requires a unit-of-measurement.
Enter Key Terminates an entry when either no unit of measure is
needed, or you want to use the default unit.
Toggle Allows you to
activate/deactivate states.
Toggles the selection (underlined
choice) each time you press the key.
