4. Device stop: Wait time due to transient time of the

voltage controller and the resulting balancing currents

in the load capacitor.

There is no difference in the execution time for a firmware

command or test function, whether the test executes for

pass/fail results or for results by value.

Due to autoranging, the measurement time depends

heavily on the value to be measured.

NOTE If you require the highest measurement accuracy (in

current measure range 1, accuracy ±100nA±0.1%), the

maximum load capacitance must not exceed 1µF. This

means that, if the DPS is operating in a higher perfor-

mance range, you will need to switch to performance

range 1 to be able to reduce the capacitive load to 1µF.

The measurement operation sequences (3 and 5 in

Figure 76 on page 164 ) is expanded in the figure below.

Figure77 Measurement Operation Sequence

1. Before the current measurement, the measurement

path will be set (operating current: 300 mA–average,

IDDQ: 100 µA–average).

2. If the measurement path is switched by the hardware,

a wait time is required.
