16 :FUNCtion Commands
Introduction to
:FUNCtion
Commands
The FUNCtion subsystem controls the math functions in the oscilloscope.
Add, subtract, multiply, and FFT (Fast Fourier Transform) operations are
available. These math operations only use the analog (vertical) channels.
The SOURce1, DISPlay, RANGe, and OFFSet commands apply to any
function.
:FUNCtion:OFFSet
<offset> (see
page 288)
:FUNCtion:OFFSet?
(see page 288)
<offset> ::= the value at center
screen in NR3 format.
The range of legal values is
+/-10 times the current
sensitivity of the selected
function.
:FUNCtion:OPERation
<operation> (see
page 289)
:FUNCtion:OPERation?
(see page 289)
<operation> ::= {ADD | SUBTract |
MULTiply | FFT}
:FUNCtion:RANGe
<range> (see
page 290)
:FUNCtion:RANGe? (see
page 290)
<range> ::= the full-scale
vertical axis value in NR3
format.
The range for ADD, SUBT, MULT is
8E-6 to 800E+3.
The range for the FFT function is
8 to 800 dBV.
:FUNCtion:REFerence
<level> (see
page 291)
:FUNCtion:REFerence?
(see page 291)
<level> ::= the value at center
screen in NR3 format.
The range of legal values is
+/-10 times the current
sensitivity of the selected
function.
:FUNCtion:SCALe
<scale
value>[<suffix>] (see
page 292)
:FUNCtion:SCALe? (see
page 292)
<scale value> ::= integer in NR1
format
<suffix> ::= {V | dB}
:FUNCtion:SOURce1
<source> (see
page 293)
:FUNCtion:SOURce1?
(see page 293)
<source> ::= {CHANnel<n> | GOFT}
<n> ::= {1 | 2 | 3 | 4} for 4ch
models
<n> ::= {1 | 2} for 2ch models
GOFT is only for FFT operation.
:FUNCtion:SOURce2
<source> (see
page 294)
:FUNCtion:SOURce2?
(see page 294)
<source> ::= {CHANnel<n> | NONE}
<n> ::= {{1 | 2} | {3 | 4}} for
4ch models, depending on SOURce1
selection
<n> ::= {1 | 2} for 2ch models
