Operated within 5730A Control Loop (all current ranges)

The current specification of the 52120A, when controlled by a single 5730A, applies to the parallel output of up to three
52120As connected as slaves.

Coverage factor k=2.58 (99 % confidence level)

Frequency
DC
10 Hz to 850 Hz
850 Hz to 6 kHz
6 kHz to 10 kHz
Notes:
1. tcal is the temperature at which calibration adjustment took place.
Maximum inductance for stability LCOMP OFF is 100 μH. Maximum inductance for stability LCOMP ON is 400 μH for 2 A and 20 A
ranges. 100 μH on the 120 A range.
With LCOMP ON, the output is limited to 7.2e3 A-Hz. For example, a 100 A output is limited to 72 Hz.

level may cause small changes to DC current offset. It is good practice
to correct for offsets in DC measurements and techniques such as DC
reversal measurement will result in best accuracy.
