Table 1- 3 shows the response for a given parameter type.
Numeric Parameters
Numeric parameters are used in both common and subsystem commands. They accept all commonly
used decimal representations of numbers including optional signs, decimal points, and scientific
notation.
If a signal generator setting is programmed with a numeric parameter which can only assume a finite
value, it automatically rounds any entered parameter which is greater or less than the finite value.
For example, if a signal generator has a programmable output impedance of 50 or 75 ohms, and you
specified 76.1 for the output impedance, the value is rounded to 75. The following are examples of
numeric parameters:
