User-defined computation is an option available only for 4-channel models. User-defined computation commands 
cannot be used on 2-channel models or 4-channel models without the user-defined computation option.
:MATH<x>?
Function  Queries all computation settings.
Syntax
  :MATH<x>?
  <x> = 1 or 2 (1 only for 2-channel models)
:MATH<x>:DISPlay
Function  Sets or queries whether or not computed 
waveforms will be displayed (on/off).
Syntax
  :MATH<x>:DISPlay {<Boolean>} 
:MATH<x>:DISPlay?
  <x> = 1 or 2 (1 only for 2-channel models)
Example
  :MATH1:DISPLAY ON 
:MATH1:DISPLAY? 
-> :MATH1:DISPLAY 1
:MATH<x>:ECOunt?
Function  Queries all edge count settings.
Syntax
  :MATH<x>:ECOunt?
  <x> = 1 or 2 (1 only for 2-channel models)
:MATH<x>:ECOunt:HYSTeresis
Function  Sets or queries the hysteresis for the edge 
detection level of edge counting.
Syntax
  :MATH<x>:ECOunt:HYSTeresis {<NRf>} 
:MATH<x>:ECOunt:HYSTeresis?
  <x> = 1 or 2 (1 only for 2-channel models) 
<NRf> = 0 to 4 (divisions)
Example
  :MATH1:ECOUNT:HYSTERESIS 1 
:MATH1:ECOUNT:HYSTERESIS? 
-> :MATH1:ECOUNT:HYSTERESIS 1.000E+00
:MATH<x>:ECOunt:POLarity
Function  Sets or queries the edge detection polarity for 
edge counting.
Syntax
  :MATH<x>:ECOunt:POLarity {FALL|RISE}

:MATH1:ECOUNT:POLARITY? 
-> :MATH1:ECOUNT:POLARITY FALL
:MATH<x>:ECOunt:THReshold
Function  Sets or queries the edge detection level for edge-
count computation.
Syntax
  :MATH<x>:ECOunt:THReshold {<NRf>| 
<Voltage>|<Current>} 
:MATH<x>:ECOunt:THReshold?
  <x> = 1 or 2 (1 only for 2-channel models)
  <Voltage>, <Current> = See the DLM2000 
Features Guide for this information.
Example
  :MATH1:ECOUNT:THRESHOLD 1 
:MATH1:ECOUNT:THRESHOLD?
