Terms Used in This Book
There are many terms used throughout this book, for example “active function block,” that 
are explained in detail in the “Getting Started” chapter of the measurements guide. It is 
recommended that you read that section first. 
The following terms are used to describe each key. Note that a key description may not use 
all the terms.
State Saved:  Indicates what happens to a particular function when the instrument 
state is saved (either to a USB drive or the internal memory). It also 
indicates whether the current settings of the function are maintained if 
the instrument is powered on or preset using 
Mode Preset or User Preset.
Dependencies/
Couplings:   Describes dependencies or interactions to other functions or settings in the 
analyzer.
Preset:  Describes the function settings after a 
Mode Preset.
Default
Terminator:  Indicates the units that will be attached to the numerical value that you 
have entered. This default will be used from the front panel, when you 
terminate your entry by pressing the 
Enter key, rather then selecting a 
units key. This default will be used remotely when you send the command 
without specifying any units after your value(s).
Range (or Min/Max):  Describes the range of the smallest to largest values to which the 
function can be set. If you try to set a value below the minimum value, the 
analyzer defaults to the minimum value. If you try to set a value above the 
maximum value, the analyzer defaults to the maximum value.
History:   Describes the firmware revision history. Only applies after second software 
release. 
Remote 
Command:  Shows the syntax requirements for each SCPI command.
Example:  Provides command examples using the indicated remote command syntax.
Mode:   Indicates to which modes a key functionality or parameter is applicable. If 
it is applicable to more than one mode, then all modes should be listed.
Key Path:  Describes how to access the menu key. The key path is described in a 
comma-separated style stating with the front-panel key name and then 
listing each menu key name needed to access the key being described. If a 
function has no front panel access (that is, a SCPI only function) this 
should indicate “None”.
