Sampling Measurements
Sampling Measurements
To make sampling measurements, use the following functions.
Table 3-25 Functions for Sampling Measurements
A program example is shown in Figure 3-37. This program measures resistance. The
example uses the User function of the Agilent VEE. See Figure 3-38 on page 3-43
and Figure 3-39 on page 3-44. The measurement setup is shown in Figure 3-36.
