[1] These values apply to sinusoidal, distorted and modulated wave-shapes.
[2] Current harmonic phase angle significantly affects the peak value of a non-sinusoidal waveform.
[3] Above 450 Hz, the instrument will drive current outputs that develop maximum compliance voltage across the load, but an “adder” to the
accuracy specification in “Current DC and Harmonic Amplitude Specifications” and “Current Distortion and Noise” may be required.
Calculation of the “adders” is described below.
[4] Compliance voltage at the end of connecting leads will be reduced by the IR drop in the cables.
[5] The current output will remain stable with the inductive loads shown but may not be able to drive that inductance at all
current/frequency/harmonic combinations due to voltage burden limitations. The inductive load due to connecting cables may be
decreased by reducing their loop area, for example, by tying the cables together or shortening the cables.
[6] In low bandwidth mode maximum frequency is 1.5 kHz.
