• MyDCSupply is the name of an external DC Source. Learn how to setup and configure an External DC Source and DC Meter.

State  Set the state of the DC source.

• ON  DC Source is always ON.

• OFF DC source is always OFF.

• Per Port  The Name selection for that DC source expands to allow an Port <n> / N/A setting for each PNA port. When the RF source for that port <n> is ON, then the DC source for port <n> is also ON. Select 'N/A' to turn the DC Source OFF for that port.

For example: In the above image...

• AO1 will be ON when the RF source at Port 1 is ON, stepping from 0 to 10V.

• AO1will be OFF when all other RF source ports are ON.

• AO2 will always be OFF

• MyDCSupply will always be ON, stepping from .5V to 1.0 V each sweep.
