4.3 CALCulation Group
:CALCulation[:MEAS<x>][:{BLOCk<x>|
BALL}]:TRF?
Function Queries the RF value when using time variation.
Syntax :CALCulation[:MEAS<x>][:{BLOCk<x>|
BALL}]:TRF?
<x> of MEAS<x>=1 to 2
<x> of BLOCk<x>=Block number (1 to
number of blocks)
BALL: Queries the statistical value
of the entire block.
Example • When measuring period, A-to-B time interval,
or pulse width and block sampling is not used
:CALCULATION:TRF?
-> :CALCULATION:TRF 1.4775E-1
• When measuring period, A-to-B time interval,
or pulse width and block sampling is used
:CALCULATION:BLOCK1:TRF?
-> :CALCULATION:BLOCK1:
TRF 1.4775E-1
• 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
:CALCULATION:MEAS1:TRF?
-> :CALCULATION:MEAS1:
TRF 1.4775E-1
Description • If the statistical value is not valid, "NAN" is
returned in response to a query.
• When the computation range is a block and
block sampling is used, specify
":{BLOCk<x>|BALL}".
• When measuring period, A-to-B time interval,
or pulse width, omit ":MEAS<x>".

:CALCulation[:MEAS<x>][:{BLOCk<x>|
BALL}]:TSDeviation?
Function Queries the standard deviation (σ) when using
time variation.
Syntax :CALCulation[:MEAS<x>][:{BLOCk<x>|
BALL}]:TSDeviation?
<x> of MEAS<x>=1 to 2
<x> of BLOCk<x>=Block number (1 to
number of blocks)
BALL: Queries the statistical value
of the entire block.
Example • When measuring period, A-to-B time interval,
or pulse width and block sampling is not used
:CALCULATION:TSDEVIATION?
-> :CALCULATION:
TSDEVIATION 2.4035E-9
• When measuring period, A-to-B time interval,
or pulse width and block sampling is used
:CALCULATION:BLOCK1:TSDEVIATION?
-> :CALCULATION:BLOCK1:
TSDEVIATION 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
:CALCULATION:MEAS1:TSDEVIATION?
-> :CALCULATION:MEAS1:
TSDEVIATION 2.4035E-9
Description • If the statistical value is not valid, "NAN" is
returned in response to a query.
• When the computation range is a block and
block sampling is used, specify
":{BLOCk<x>|BALL}".
• When measuring period, A-to-B time interval,
or pulse width, omit ":MEAS<x>".
