1-15. Open and Closed Loop Operation

Full accuracy for pure sine or sine plus harmonics is achieved by using analog and digital feedback systems (closed
loop). When any of: Flicker, Fluctuating harmonics, Dip/Swell or Interharmonics are applied, the digital system is
automatically uncoupled (open loop). Initial performance is as described in the 1-year accuracy column but
performance degrades with time as described by the stability column. Full accuracy can be restored by momentarily
disabling whichever of Flicker, Fluctuating harmonics, Dip/Swell or Interharmonics are enabled, or by changing the
value of the sine wave or any harmonic for that channel.

[1] These values apply to sinusoidal, distorted and modulated wave-shapes.
[2] Voltage harmonic phase angle significantly affects the peak value of a non-sinusoidal waveform.
[3] To achieve specifications in 4-wire sense, resistance in the sense lead must be less than 1 Ω and resistance in the
power leads less than 1.5 Ω.

[1] Four-wire sense only, for two-wire operation, add an additional voltage = 0.3
[2] For 1 C and constant load and connection conditions.
[3] When Flicker, Fluctuating harmonics, Dip/Swell or Interharmonics are applied, Open Loop Stability specification must be added to the 1-
year accuracy specification as described in "Open and Closed Loop Operation".
[4] tcal = temperature of last calibration.
[5] Output levels less than the range minimum can be set but are not specified.
[6] These specifications assume a 'sampling' measuring instrument. Some rms sensing instruments have voltage input bandwidths of several
MHz. The 6100A specification should be expanded by the non-harmonic noise floor in the "Voltage Distortion and Noise" table for rms
sensing devices.
