get(math=Math.Default) → str[source]
# CALCulate:MATH<*>[:EXPRession][:DEFine]
value: str = driver.calculate.math.expression.define.get(math = repcap.Math.Default)

Defines the math expression to be calculated for the specified math channel. Operation / <Expression> / Comment

  • Addition / ‘C1+C2’

  • Subtraction / ‘C1-C2’

  • Multiplication / ‘C1``*C2``’

  • Division / ‘C1/C2’ / 0/0 = 0 +1 / 0 = Clip+ -1 / 0 = Clip

  • Inverting / ‘-C1’

  • Absolute value / ‘Abs(C1) ‘

  • Derivation / ‘Derivation(C1,NoiseReject) ‘ / NoiseReject can get any value between 1 and 5000 points Default = 50

  • Integral / ‘Integral(C1) ‘

  • Logarithm (based on 10) / ‘Log(C1) ‘ / Uses the absolute value of the source in calculation. Log(0) = Clip

  • Natural logarithm (based on e) / ‘Ln(C1) ‘ / Uses the absolute value of the source in calculation. Log(0) = Clip

  • Binary logarithm (based on 2) / ‘Ld(C1) ‘ / Uses the absolute value of the source in calculation. Log(0) = Clip

  • Square / ‘Pow(C1) ‘

  • Square root / ‘Sqrt(C1) ‘ / Uses the absolute value of the source in calculation.

  • Rescale / ‘Rescale(C1,a,b) ‘ / a = scale, default = 1 b = offset, default = 0

  • FIR / ‘FIR(Type,C1,Cut-Off,Characteristics) ‘ Examples: ‘FIR(highpass,C1,10000000,Gaussian) ‘ ‘FIR(lowpass,C1,10000000,rectangle) ‘ / Type = lowpass, highpass Cut-Off = limit frequency Characteristics = Gaussian, rectangle Cut-Off can get any value between 4 GHz and 1 kHz

Parameters:

math – optional repeated capability selector. Default value: Nr1 (settable in the interface ‘Math’)

Returns:

expression: String with regular expression for calculation
