Notes:
Maximum output from 5730A terminals is 2.2 A. Accuracy specifications for 220 μA and 2.2 mA ranges are increased by a factor of
1.3, plus 2 μA when supplied through 5725A terminals. Specifications are otherwise identical for all output locations.
1. Stability specifications are included in the Absolute Accuracy values for the primary specifications.
2. Temperature coefficient is an adder to accuracy specifications that does not apply unless operating more than ±5 °C from
calibration temperature.
3. For larger resistive loads multiply accuracy specifications by: (
accuracy full for load maximum
load actual
)

4. 1.5 V compliance limit above 1 A. 5725A Amplifier may be used in range-lock mode down to 1 A.
5. For resistive loads within rated compliance voltage limits.
Minimum Output .................................................... 9 μA for 220 μA range, 10 % on all other ranges. 1 A minimum for
5725A.
Inductive Load Limits ........................................... 400
μH (5730A, or 5725A). 20 μH for 5730A output >1 A.
Power Factors ........................................................ 5730A, 0.9 to 1; 5725A, 0.1 to 1. Subject to compliance voltage
limits.
Frequency:
Range (Hz) .......................................................... 10.000 - 11.999, 12.00 - 119.99, 120.0 - 1199.9, 1.200 k - 10.000 k
Accuracy ........................................................ ±0.01 % of output
Resolution ..................................................... 11,999 counts
Settling Time ...................................................... 5 seconds for 5730A ranges; 6 seconds for 5725A 11 A range; +1
second for amplitude or frequency range change.
Overshoot .......................................................... <10 %
