| Benchtop Power Supply with 0.05 mV step resolution? |

Hi everyone, I tried to search the forums first, but couldn't find an answer. I am looking to simulate a sensor for a transmitter I am designing. I am looking for a benchtop programmable power supply that has a step resolution of 0.05mV or lower. The max voltage out I need is only ~110 mV. Very little current output is required at most 50mA. I am not worried about cost (Its for the company I work for). Thanks, - James |

You need a source measurement unit (SMU) |

Use a bench programmable supply with a 1mV resolution driving an opamp configured for a gain of 1/20 ? |

Unfortunately I don't know of a modern replacement other than a SMU, but the Keithley 230 voltage source would have been perfect for this: a 200 mV range with 50 uV resolution, up to 100 mA output current. When working professionally and not severely limited by budget, I wouldn't mess with building my own attenuator, but rather buy a device that can directly generate the output you need. I'm not quite sure what else, other than an SMU (which would be overkill), is available. |
