Waveform Parameters
Computations can be made using measured values of waveform parameters. Power
supply analysis parameters can also be used if the power supply analysis function (/G4
option) is installed.
• Displayed waveform parameters are preceded with a P
. in equations.
• Waveform parameter values cannot be acquired when display
of the waveform under
test is turned OFF.
•
If the area is omitted,
Area 1 is used.
Examples of Entering Equations
Example of input other than DIFF, INTEG, DELAY, or BIN
Equations can be defined by combining waveforms and constants with operators.
SIN(PI) Using a constant with an operator
COS(C1) Using a waveform with an operator
ABS(C1+C2*2) Waveform and constant expressions referenced in an operator
SQRT(ABS(C1+C2*2)) Referencing an operator within another operator
Entering Differentials and Integrals
Waveforms or expressions including waveforms can be referenced by the DIFF and
INTEG operators.
DIFF(5) Invalid because 5 is a constant
INTEG(K1+10) Invalid because K1+10 includes a constant
DIFF(C1/3) C1/3 part
INTEG(INTEG(C3)) Double integral of C3
DIFF(DIFFC4)) Double differential of C4
Entering DELAY (Phase Shift)
DELAY is set in the format DELAY (waveform, constant).
Waveform:
The waveform to be phase-shifted. Entered using a monomial of 1
waveform
Constant:
The amount of shifting. Entered using a constant o
r a constant expression.
DELAY(C1,C2) Invalid because the phase shift amount is a constant or a constant
expression
DELAY(C1+C2,5) Invalid because the phase shifted waveform is not a monomial of
1 waveform
DELAY(C1,5E-3) Phase-shifts waveform C1 by 0.005
DELAY(C2,P.Period(C2)*2) Phase-shifts waveform C2 by “2 periods of waveform C2”)
Entering BIN (Binarization)
BIN is set in the format BIN(waveform, constant1, constant2).
W
aveform: The waveform to be binarized. Entered using a constant or a constant
expression.
Constant1:
Specifies the threshold level (Level). Entered usin
g a constant or a
constant expression.
Constant2:
Specifies the hysteresis (Hys). Entered using a co
nstant or a constant
expression.
BIN(5,10,2) Invalid because the source waveform is not a waveform
BIN(C1,C2,C3) Invalid because the Level and Hys are not constants or constant
expressions
BIN(C1+C2) Binarizes C1 + C2 with Level = 0 and Hys = 0
BIN(C2,P.Mean(C2)) Binarizes C2 with Level = “mean of waveform C2” and Hys = 0
BIN(C1,1,P.PP(C1)/10) Binarizes C1 with Level = 1 and Hys = “1/10 of the P-P value of
waveform C1”
