Why Is My DC Output Voltage Not What I Expect?
The output impedance for the FGEN is 50 Ω. The load impedance that you put on the output will cause a voltage divider with the 50 Ω output impedance and reduce the voltage compared to what you program. For example, if you have a 50 Ω load, you will see half the amplitude. If you have a 100 Ω load, you will see 2/3 the amplitude. If you have a high impedance load, such as a DMM, you will see 100% of the programmed value. The output is designed to drive a load ≥50 Ω. A smaller load may cause an unexpected error.
