Quasi-Pulsed Spot Measurements
Quasi-pulsed spot measurement is performed as shown below. The measurement
channel performs one point measurement while the source channel forces a
quasi-pulse voltage. This measurement mode can minimize the output time of the
measurement voltage. So it is effective for the breakdown voltage measurement and
the reliability test.
Figure 2-10 Quasi-Pulsed Spot Measurements
1. The quasi-pulse source channel sets output by the BDT, BDM, and BDV
commands. Only one channel can be used for the quasi-pulse source.
2. The quasi-pulse source starts output by a trigger, such as the XE command.
3. After the hold time, the quasi-pulse source starts the voltage transition to the
stop value (settling detection time). Also, it performs voltage measurement
(settling detection) in the interval set by the BDM command. The voltage
transition and settling detection continue until the output voltage slew rate
becomes half of the rate when settling detection started. The slew rate depends
on the cabling and the characteristics of the device. You cannot define it directly.
In normal operation, the slew rate will be slower in the following conditions:
• When the quasi-pulse source applies voltage close to the stop value.
• When the quasi-pulse source reaches its current compliance due to the
breakdown condition of the device under test.
NOTE If the slew rate was too slow when settling detection started or if the settling
detection time was too long, an error occurs and the source returns its output to the
start value immediately. See
“BDM” on page 4-26 .
