Querying numeric values
When you query numeric values, the system returns a number. In case of physical
quantities, it applies the basic unit (e.g. Hz in case of frequencies). The number of dig-
its after the decimal point depends on the type of numeric value.
Example:
Setting:
SENSe:FREQuency:CENTer 1GHZ
Query:
SENSe:FREQuency:CENTer?
would return
1E9
In some cases, numeric values may be returned as text.
●
INF/NINF
Infinity or negative infinity. Represents the numeric values 9.9E37 or -9.9E37.
●
NAN
Not a number. Represents the numeric value 9.91E37. NAN is returned in case of
errors.

Boolean
Boolean parameters represent two states. The "ON" state (logically true) is represen-
ted by "ON" or a numeric value 1. The "OFF" state (logically untrue) is represented by
"OFF" or the numeric value 0.
Querying Boolean parameters
When you query Boolean parameters, the system returns either the value 1 ("ON") or
the value 0 ("OFF").
Example:
Setting:
DISPlay:WINDow:ZOOM:STATe ON
Query:
DISPlay:WINDow:ZOOM:STATe?
would return
1
6.1.6.3
Character Data
Character data follows the syntactic rules of keywords. You can enter text using a short
or a long form. For more information see
Chapter 6.1.2, "Long and Short Form"
Querying text parameters
When you query text parameters, the system returns its short form.
Example:
Setting:
SENSe:BANDwidth:RESolution:TYPE NORMal
Query:
SENSe:BANDwidth:RESolution:TYPE?
would return
NORM
