PWHH to DUTYL (Pulse Width Computation) Examples
Syntax: PWHH(parameter 1,parameter 2,parameter 3)
Parameter 1: Set the waveform to compute the pulse width of. Enter a single waveform.
Parameter 2: Set the upper threshold level. Enter a constant or a constant expression.
Parameter 3: Set the lower threshold level. Enter a constant or a constant expression.
PWHH(C1,K1,K2) Compute the pulse width of waveform C1 with Upper set to K1 and
Lower set to K2
DUTYH(C2,P.High(C2),P.Low(C2)) Compute the pulse width of waveform C2 with Upper set to waveform
C2’s high value and Lower set to waveform C2’s low value.
PWHH(5,10,2) Not allowed because parameter 1 is not a waveform
PWHL(C1,C2,-1) Not allowed because parameter 2 is not a constant or a constant
expression
PWLL(C1+C2,1,-1) Not allowed because parameter 1 is not a single waveform
Examples of Other Operators
Syntax: Operator(parameter)
Parameter: Specify a waveform, a constant, or an expression.
SIN(PI) Example in which the parameter is set to a constant
COS(C1) Example in which the parameter is set to a waveform
ABS(C1+C2*2) Example in which the parameter is set to an expression that consists
of waveforms and a constant
SQRT(ABS(C1+C2*2)) Example in which the parameter is set to an expression
SIN(2*PI*T*K1) Example in which the parameter is set to an expression (that consists
of elapsed time T and constants)
Combinations of Operators That Are Not Allowed
The Math1 expression cannot contain the Math2 expression.
Example: Math1=M2+C3
An expression can only contain up to two FILT1 or FILT2 functions.
Example: FILT1(C1)+FILT1(C2)+FILT1(C3)
Computation cannot be performed on a computed pulse width.
Example: PWHH(C1, 1, 0)+C2
When converting to binary values or when computing pulse width, the source waveform can only be a single
waveform.
Examples: BIN(C1-C2, 1, -1), PWHH(C1*C2, 0, 0)
Note
• Averaging cannot be performed on pulse width computation.
• If you want to covert the result of a computation such as C1+C2 to binary values or perform pulse width
computation on it, define the Math1 and Math2 expressions in this manner: Math1 = C1+C2 and Math2 =
BIN(M1, 0, 0).
