WGFMU provides an all-in-one high-speed IV characterization solution

Powerful combination of DC/AC waveform generation and synchronized fast

measurement

The WGFMU is an innovative parametric module that integrates ALWG

capability with high-speed IV measurement. The ALWG function allows you

to generate not only DC, but also various types of AC waveforms (such as

pulses, staircase sweeps, and staircase pulsed sweeps) with 10 ns program-

mable resolution. In addition, the WGFMU also performs fast AC measure-

ment in synchronization with the applied waveforms. The combination of

these capabilities into a single, dual-channel module enables the character-

ization of complex high-speed phenomena without the need to switch

between different resources to do the DC/AC voltage forcing and the current

or voltage measurement. This makes the WGFMU a powerful solution for a

wide range of transient and time-domain phenomena.

WGFMU Features Benefits

Solves many complex test challenges without the need for

additional equipment and complicated external cabling.

A single module can do the job of a PGU and oscilloscope.

Much better measurement resolution than that

obtained using a PGU and oscilloscope.

High accuracy current measurement

(down to nanoamps) and 0.2% range

resolution without averaging

Fast and flexible DC/AC waveform generation

(ALWG) combined with accurate, high-speed

synchronized IV measurement in a single module

The remote-sense and switch units (RSUs)

that accompany each WGFMU channel

mount directly on the wafer prober

to minimize cabling and parasitic

effects and to maximize meas-

urement accuracy.

One module meets most single-device testing needs. Multiple

devices can be tested in parallel, reducing the cost of test.

Pulsed IV, Fast NBTI, RTS noise and many other tests can be

done with the same module.

Versatile architecture supports

a wide range of applications

Up to five two-channel modules supported by the

B1500A (up to ten independent test channels)
