Command Descriptions

AWG710&AWG710B Arbitrary Waveform Generator User Manual

min(a, b)

Returns smaller (minimum) value of a and b.

noise()

Generates pseudo Gaussian distribution white noise signal with a standard 
deviation (= RMS) of 1.

pow(a,b)

Exponentiation (bth power of a, or a^b)

A negative value may be specified for a only if b is an integer. Otherwise, NaN 
will result. The pow function returns one of the following values:

If b = 0: Always 1
If b 

≠

 0 and a = 0: Always 0

If b 

≠

 0 and a < 0 and b is a positive integer: a*b

If b 

≠

 0 and a < 0 and b is a negative integer: Reciprocal of a*(-b)

If b 

≠

 0 and a < 0, NaN (Not a Number)

rnd()

Returns a random number in the 0 to 1 range.
Generated base seed = (253 * seed + 1)% 16777216, 
return seed/16777216. Seed is a 32–bit unsigned integer.

round(a)

Rounds off the value of a to an integer.

saw(a)

Saw tooth wave with a cycle of 2

π

 and an amplitude ±1.

If a = -2

π

, 0, 2

π

, 4

π

, or 6

π

, etc., the value is -1. 

The value approaches 1 at points immediately before these. 
(This function will not take the value 1.0.)

sign(a)

Sign of a (1 if a > 0; –1 if a < 0; 0 if a = 0).

sin(a)

Sine value of a.

sinc(a)

Same as sin(a)/a, except that 1 results if a=0.

sinh(a)

Hyperbolic sine value of a.

sqr(a)

Rectangular wave with a cycle of 2

π

 and an amplitude ±1.

If k is an even:
For a = k

π

 to (k+1)

π

, sqr returns -1, except +1.0 when a equals (k+1)

π

.

If k is an odd:
For a = k

π

 to (k+1)

π

, sqr returns +1, except -1.0 when a = (k+1)

π

.

sqrt(a)

Square root value of a.

srnd(seed)

Sets the random number generator seed value. Seed is 0 to 2

31

-1. 

Default value is 0.

tan(a)

Tangent value of a.

tanh(a)

Hyperbolic tangent value of a.

tri(a)

Triangular wave with a cycle of 2

π

 and an amplitude ±1.

If a = 0, the value is 0. If a = 0.5

π

, it is 1.0. 

If a = 

π

, it is 0.0. If a = 1.5

π

, it is -1.
