2- 68 Agilent B1500 User’s Guide, Edition 7
Introduction
Specifications
Measurement time resolution: 100 μs
• Standby mode
SMUs in “Standby” remain programmed to their specified o
utput value even as
other units are reset for the next measurement.
• Current offset cancel
This function subtracts the offset current from the current measurement raw
data, an
d 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.
• Timestamp
The B1500A supports a time stamp function utilizing an internal quartz clock.
Resolution: 100 μs
• Other measurement characteristics
• Measurement control:
Single, repeat, append, and stop
• SMU setting capabilities:
Limited auto ranging, voltage/current compliance, power compliance,
au
tomatic s
weep abort functions, self-test, and self-calibration
Arithmetic and analysis functions
• User functions
Up to 20 user-defined functions can be defined using arithmetic expressions.
Measured data and pre-defined variables can be used in the computation. The
results can be di
splayed on the LCD.
• Arithmetic operators
+, -, *, /, ^, abs (absolute value), at (arc tangent), avg (averaging), cond
(conditio
nal evaluation), delta, diff (differential), exp (exponent), integ
(integration), lgt (logarithm, base 10), log (logarithm, base e), mavg (moving
average), max, min, sqrt, trigonometric function, inverse trigonometric function,
and so on
• Physical constants
Keyboard constants are stored in memory as follows:
