You can also perform a frequency sweep (up or down):
• DC bias waveform: The DC bias is set to 0V, but can be set to any valid DC bias level (you
specify the number of measurements to perform). (see Figure 1-15 )
• DC voltage sweep: You specify the start voltage, stop voltage and step voltage. The number
of data (measurement) points is calculated by the 4210-CVU. (see
Figure 1-16 )
• Frequency sweep: You specify the start frequency and the stop frequency; the number of
data (measurement) points is calculated by the 4210-CVU. (see Figure
1-17 )
• Voltage list sweep: You specify the voltage levels for the sweep (not shown)
• Step frequency sweep: Includes voltage stepping. A voltage sweep is performed for every
frequency point (not shown)
NOTE Refer to the Forcing functions and measure options, page 3-16 for details on the bias
and sweep forcing functions.
