DC Probes
DC Probes
The MOSFET contact pads for DC measurement shown in Figure 2-3 , are more
popular than the RF contact pads shown in Figure 2-2 . If device under test is
configured with DC contact pads, use DC probes instead of RF probes. The DC
probes are better suited for contact with the DC contact pads than the RF probes.
See
Figure 2-3 for the contact pads and the DC probes. Required cables for
connecting the DC probes are furnished with the B1542A as the DC probe cable set.
For more information, see
“Connecting DC Probes” on page 2-14 .
When using DC probes, minimum pulse width should be limited to approximately
60 ns to 100 ns.
