PicoScope 7 Software
Available on Windows, Mac and Linux
Some applications require the recording and graphing of a calculated parameter containing data from one or more measurement channels. PicoLog 6 is equipped with an equation editor to perform simple calculations such as A–B, or more complex functions such as log, sqrt, abs, round, min, max, mean and median.
Math channels are treated like any normal channel, so you can perform functions like alarms, graphing and annotations on them.
Brackets:
Standard arithmetic functions
Power: x ^ y
Calculates the power of x to y.
Exponential: e ^ x
Calculate the exponent of a value
Modulus: x % y
Calculates the modulus, the remainder of an integer division
Factorial: x!
Compute the factorial of a value Factorial only supports an integer value as argument.
Log: log(x [,base])
Calculate the logarithm of a value, square brackets are optional parameters. Optionally use Log 10: log10(x)
Calculate the 10-base logarithm of a value.
ln: log(x, e)
Calculate the logarithm to the base e of x
Square root: sqrt(x)
Calculate the square root of a value
Absolute: abs(x)
Calculate the absolute value of a number
Ceiling: ceil(x)
Round a value towards plus infinity
Floor: floor(x)
Round a value towards minus infinity
Round: round(x[, n])
- Round towards nearest integer
and: x and y
Boolean AND two values
or: x or y
Boolean OR two values
not: not x
Boolean NOT value
xor: x xor y
Boolean XOR two values
Maximum: max(a, b, c...)
Compares all the values in the list and return the maximum number
Minimum: min(a, b, c...)
Compares all the values in the list and return the minimum number
Mean: mean(a, b, c...)
Computes the mean value from the list of values
Median: median(a, b, c...)
Computes the median value from the list of values
Sine: sin(x)
Calculate the sine of a value.
Cosine: cos(x)
Calculate the cosine of a value
Tangent: tan(x)
Calculate the tangent of a value
Conditional expression: operand1 ? operand2 : operand3
- The conditional operator (? :) is a ternary operator (it takes three operands). E.g. x > 0 ? x*4 : x*3
The conditional operator works as follows:
Device disconnected: x == disconnected
where x is the data from a channel
Pi: The number pi is a mathematical constant that is the ratio of a circle's circumference to its diameter (3.141592653589793)
