This function allows you to keep a source
active between measurements. The
source module will apply the specified
bias between measurements when run-
ning classic tests inside an application
test, in quick test mode, or during a
repeated measurement. The function
ceases as soon as these conditions end
or when a measurement that does not
use this function
Measurement data and calculated user
function data are listed in conjunction
with sweep step number or time domain
sampling step number. Up to 20 data
sets can be displayed.
Data variable display
Up to 20 user-defined parameters can be

Sampling (time domain) mea-
surement
This function subtracts the offset cur-
rent from the current measurement
raw data, and returns the result as the
measurement data. This function is used
to compensate the error factor (offset
current) caused by the measurement
path such as the measurement cables,
manipulators, or probe card.
Time stamp
The B1505A supports a time stamp
function utilizing an internal
quartz clock.
Resolution: 100 μs

using the auto analysis setup. Parameters
can be automatically determined using
automatic analysis, user function, and read
out functions.
Displays the time sampled voltage/current
data (by SMU) versus time.
