Ta ble 6-3 Functions
Name Function
Intg( Calculate the integral of the selected source. You can use integral
to measure the area under a waveform or the pulse energy.
Diff( Calculate the discrete time differential of the selected source. You
can use differential to measure the instantaneous slope of a
waveform.
Lg( Calculate the common logarithm of the selected source (use 10 as
the base).
Exp( Calculate the exponent of the selected source. For example,
Exp(A) means calculate the Ath power
of e.
Sqrt( Calculate the square root of the selected source.
Sine( Calculate the sine value of the selected source.
Cosine( Calculate the cosine value of the selected source.
Tangent( Calculate the tangent value of the selected source.
4. Variable
Users can set the desired values of Variable1 and Variable2 using the following
method.
Press Variable to turn on the variable setting menu.
Variable: press this softkey to select the variable to be set as “Variable1”
and “Variable2”.
Step: press this softkey to set the step used when using
to modify the
“Mantissa”. The steps available are × 1, × 0.1, × 0.01, × 0.001 and ×
0.0001.
Mantissa: press this softkey and turn
to modify the mantissa at the
step specified in Step. The range available is from -9.9999 to 9.9999.
Exponent: press this softkey to set the numeric values of the exponents
with 10 as the bottom number in the variables. The range is from -9 to 9.
