:MATH<x>:BINary:{CHANnel<x>|MATH1}
Function
Sets the threshold levels of the channel for
binary computation or queries the current
setting.
Syntax
:MATH<x>:BINary:{CHANnel<x>|MATH1}
{<Voltage>,<Voltage>|<NRf>,<NRf>}
<x> of MATH<x>=1 or 2 (1 on the DL1720E)
<x> of CHANnel<x>=1 to 4 (1 to 2 on the
DL1720E)
<Voltage>=8 divisions within the screen (0.01
division steps)
<NRf>=–4 to 4 div (0.01 div steps)
Example
:MATH1:BINARY:CHANNEL1
0V,0V:MATH1:BINARY:CHANNEL1? ->
:MATH1:BINARY:
CHANNEL1 0.000E+00,0.000E+00
Description
• The “
:MATH<x>:BINary:MATH1
” command
can be used when <x>=2. An error occurs if
<x>=1. (There is no MATH2 on the DL1720E
so this command cannot be used.)
• When a current probe is used, this command
sets or queries the <Current> value.
:MATH<x>:DISPlay
Function
Sets whether or not to display computation
waveforms or queries the current setting.
Syntax
:MATH<x>:DISPlay {<Boolean>}
:MATH<x>:DISPlay?
<x>=1 or 2 (1 on the DL1720E)
Example
:MATH1:DISPLAY ON
:MATH1:DIPSLAY? -> :MATH1:DISPLAY 1

Example
:MATH1:FFT? -> :MATH1:FFT:
POINTS 1000;WINDOW RECTANGLE;
SPOINT -5.0000000
:MATH<x>:FFT:POINts
Function
Sets/queries the number of points for FFT
computation.
Syntax
:MATH<x>:FFT:POINts {<NRf>}
:MATH<x>:FFT:POINts?
