Simulation errors.. SOLVED

mrobbins, I'm trying to get a simulation working for my modulator circuit. I can't get the DC sim to resolve the circuit, and the DC Sweep doesn't seem to do anything either. Can anyone tell me what I'm doing wrong?? Thanks.

To start with, the Ammeters basically act as short-circuits, which is not what you want.

My suggestion would be for you to delete the voltmeter and ammeter components from this schematic. You can measure currents and voltages in an easier way without them anyway!

Thanks, I tried what you suggested, it got the sim working. I would like to get an amps readout at nodes 1 and 2. How can I do this having removed the ammeters?

  1. Click "Run DC Solver"
  2. Move your mouse to hover over the actual endpoints of individual components. Move around until the terminal of the component lights up. You can then click that point and get a current readout.

(You have to take a current reading at a component terminal, rather than on a wire in the schematic.)

mrobbins, Thanks, that worked really well. Got the volts, and the amps.
