These three UTMs are functionally identical but simpler than their respective
routines listed earlier in this section of the manual. The difference being less-used
parameters have been eliminated from the parameter list and hard-coded (for
example, SMU channels, ranges, load line).
How to perform a Quiescent-point Pulsed I-V test (PIV-Q) on my
device
Q-Point Pulse IV – Model 4200-PIV-Q
This application provides q-point pulse IV testing for higher power compound
semiconductor or LDMOS RF transistors, or any device may benefit from low duty
cycle pulse IV testing. This application uses the 4200-PIV-Q package, which
differs from the 4200-PIV-A package by:
1) Pulsing both the gate and drain
2) Providing higher power to the DUT drain
3) Pulsing from non-zero bias point, or quiescent point, testing
The compound semiconductor transistors consist of materials made from the III-V
groups in the periodic table of the elements, but other groups or elements may be
