Bias Tee, Option 10 10-3 How Bias is Generated
Vector Network Analyzer MG PN: 10580-00289 Rev. K 10-3
Figure 10-2 shows how the MS20xxC can provide an internal voltage between 12 volts and
32 volts that can be switched between Port 1 and Port 2. That voltage would be available at
the port along with the RF signals. Alternatively, an external voltage source could be
connected to the Bias Tee input ports in order to provide a bias voltage between +50 volts and
–50 volts at both ports simultaneously, if desired.
