    Between above values: follow the manufacturer’s recommendation 3.2.6 Signal Source Output Impedance U2810D provides two different signal output impedance 30Ω and 100Ω. The measurement current through the DUT will be different with different signal output impedance under the test same signal voltage level. The current sensitive components, for example the inductors with cores, will get different measurement results under different signal source output impedance.
