:MATH<x>:EXPRession
Function
Sets the equation or queries the current setting.
Syntax
:MATH<x>:EXPRession {<string>}
:MATH<x>:EXPRession?
<x> = 1, 2
<string> = 50 characters or less
Example
:MATH1:EXPRESSION "C1"
:MATH1:EXPRESSION?→:MATH1:
EXPRESSION "C1"
Description
Characters and symbols other than the ones
displayed on the keyboard on the screen
cannot be used.
:MATH<x>:FFT?
Function
Queries all settings related to the FFT.
Syntax
:MATH<x>:FFT?
<x> = 1, 2
Example
:MATH1:FFT?→:MATH1:FFT:POINT 1000;
WINDOW RECTANGLE
Description
This command is applicable to both MATH1
and MATH2. Specifying <x> has no meaning.
:MATH<x>:FFT:POINt
Function
Sets the number of points for the FFT or
queries the current setting.
Syntax
:MATH<x>:FFT:POINt {<NRf>}
:MATH<x>:FFT:POINt?
<x> = 1, 2
<NRf> = 1000, 2000, 10000
Example
:MATH1:FFT:POINT 1000
:MATH1:FFT:POINT?→:MATH1:FFT:POINT 1000
Description
This command is applicable to both MATH1
and MATH2. Specifying <x> has no meaning.
:MATH<x>:FFT:WINDow
Function
Sets the window function for the FFT or queries
the current setting.
Syntax
:MATH<x>:FFT:WINDow {RECTangle|HANNing}
:MATH<x>:FFT:WINDow?
<x> = 1, 2
Example
:MATH1:FFT:WINDOW RECTANGLE
:MATH1:FFT:WINDOW?→:MATH1:FFT:
WINDOW RECTANGLE
Description
This command is applicable to both MATH1
and MATH2. Specifying <x> has no meaning.

:MATH<x>:FUNCtion
Function
Enables/disables the computation function or
queries the current setting.
Syntax
:MATH<x>:FUNCtion {<Boolean>}
:MATH<x>:FUNCtion?
<x> = 1, 2
Example
:MATH1:FUNCTION ON
:MATH1:FUNCTION?→:MATH1:FUNCTION 1
Description
The "
:DISPlay:WAVE:MATH<x>
be used to make the same settings and
inquiries.
:MATH<x>[:MODE]
Function
Turns ON/OFF the computation or queries the
current setting.
Syntax
:MATH<x>[:MODE] {<Boolean>}
:MATH<x>:MODE?
<x> = 1, 2
Example
:MATH1:MODE ON
:MATH1:MODE?→:MATH1:MODE 1
Description
This command is applicable to both MATH1
and MATH2. Specifying <x> has no meaning.
:MATH<x>:POINt
Function
Sets the start and end points of the computation
or queries the current setting.
Syntax
:MATH<x>:POINt {<time>,<time>|<NRf>,
<NRf>}
:MATH<x>:POINt?
<x> = 1, 2
<time> = 0 to (OBSERVATION TIME) (during
the normal measurement mode,
when Time Base = Internal)
<NRf> = 0 to Record length (when Time
Base = Internal, or during the
harmonic measurement mode)
Example
:MATH1:POINT 10MS,90MS
:MATH1:POINT?→:MATH1:POINT 10.000E-03,
90.000E-03
Description
• Set the start point, then the end point.
• The range and resolution of <time> depends
on the observation time.
• This command is applicable to both MATH1
and MATH2. Specifying <x> has no
meaning.
• Specify <NRf> in terms of sampled data
points. The range is from 0 to the record
length.
:MATH<x>:SCALing?
Function
Queries all settings related to converting the
scale.
Syntax
:MATH<x>:SCALing?
<x> = 1, 2
Example
:MATH1:SCALING?→:MATH1:SCALING:
MODE AUTO;VALUE 0.1000,0.0000
