Test signal
The test signal can be set for the following frequencies:
• 1 kHz to 10 kHz in 1 kHz increments
• 10 kHz to 100 kHz in 10 kHz increments
• 100 kHz to 1 MHz in 100 kHz increments
• 1 MHz to 10 MHz in 1 MHz increments
The AC signal output level can be set from 10 mV
RMS
to 100 mV
RMS
(1 mV
RMS
resolution). The output
impedance is 100 Ω (typical). The AC voltage measure range is 100 mV
RMS
.
The ranges available to measure current are 1 µA, 30 µA, or 1 mA. With autorange selected, range
selection is done automatically.
DC bias function and sweep characteristics
The AC test signal can be biased with a static DC level (−30 V to +30 V), or a voltage sweep (up or
down). You can also perform a frequency sweep (up or down).
The next figure shows an example of DC bias waveform. In this example, the DC bias is set to 0 V,
but you can set it to any valid DC bias level. You specify the number of measurements to make.

The next figure shows an example of DC voltage sweep. You specify the start voltage, stop voltage,
and step voltage. The number of measure points is calculated by the 4210-CVU.
