Table 29 Bypass Capacitance to Filter Out GPDPS Related Noise

For noise-sensitive applications, we recommend a capaci-

tance of 1 µF. Larger values will reduce measurement

accuracy.

Switching DPS Voltages (Vbump)

Switching of DPS voltages is, for example, needed in data

retention tests.

You can switch between two programmed power supply

voltages without stopping the test using the digital V

bump

feature. This feature allows you to program a change in the

power supply voltage during device operation.

The advantages are:

• the supply voltage can be switched during execution of

the pattern

• the measurement can be synchronized with the vector

pattern

• all GPDPS channels can be triggered at one time

NOTE Each GPDPS channel provides two voltage DACs. The

bump

functionality lets you switch between the two

voltage DACs on the DPS channel.

One Vbump trigger input is provided per DPS board. The

trigger signal triggers Vbump simultaneously on all 4 DPS

channels of the GPDPS board. However, you can set a

mask in the level setup window to trigger only a subset of

the 4 channels if you wish.
