:CALCulation[:MEAS<x>][:{WINDow<x>|
SUMMation}]:SDEViation?
Function
Queries the standard deviation (σ) when using
histogram.
Syntax
:CALCulation[:MEAS<x>][:{WINDow<x>|
SUMMation}]:SDEViation? [{POSitive|
NEGative|ALL|SELect}]
<x> of MEAS<x>=1 to 2
<x> of WINDow<x>=Window number (1
to number of windows)
SUMMation: Queries the statistical
value when all windows are
accumulated.
Example
When in time stamp/hardware histogram
mode
• When measuring period, A-to-B time interval,
or pulse width and single window is used
:CALCULATION:SDEVIATION?
-> :CALCULATION:
SDEVIATION 2.4035E-9
• When measuring period, A-to-B time interval,
or pulse width and multi window or auto
window is used
:CALCULATION:WINDOW1:SDEVIATION?
-> :CALCULATION:WINDOW1:
SDEVIATION 2.4035E-9
• When measuring period A & period B, period
A & A-to-B time interval, pulse width A & A-to-
B time interval, and pulse width A & pulse
width B and single window is used
:CALCULATION:MEAS1:SDEVIATION?
-> :CALCULATION:MEAS1:
SDEVIATION 2.4035E-9
• When measuring period A & period B, period A
& A-to-B time interval, pulse width A & A-to-B
time interval, and pulse width A & pulse width
B and multi window or auto window is used
:CALCULATION:MEAS1:WINDOW1:
SDEVIATION?
-> :CALCULATION:MEAS1:WINDOW1:
SDEVIATION 2.4035E-9
When in inter-symbol interference analysis
mode
:CALCULATION:WINDOW1:SDEVIATION?
ALL
-> :CALCULATION:WINDOW1:
SDEVIATION 2.4035E-9
Description • If the statistical value is not valid, "NAN" is
returned in response to a query.
• When using single window, omit
":{WINDow<x>|SUMMation}".
• When measuring period, A-to-B time interval,
or pulse width, omit ":MEAS<x>".
• When ":CALCulation:POLarity" is set to
"POSNeg", specify "POSitive|NEGative".
• When in inter-symbol interference analysis
mode, specify "ALL|SELect".

to number of windows)
SUMMation: Queries the statistical
value when all windows are
accumulated.
Example

or pulse width and single window is used
:CALCULATION:SNUMBER?
-> :CALCULATION:SNUMBER 6.000E+3

SNUMBER 6.000E+3
• When measuring period A & period B, period
A & A-to-B time interval, pulse width A & A-to-
B time interval, and pulse width A & pulse
width B and single window is used

-> :CALCULATION:MEAS1:
SNUMBER 6.000E+3
• When measuring period A & period B, period
A & A-to-B time interval, pulse width A & A-to-
B time interval, and pulse width A & pulse
width B and multi window or auto window is
used
