Technical data

The new N3280A dc source offers
semiconductor ATE manufacturers
a reduction in test time, integration
time and rack space. It is a fast,
low-power four-output (±10 V/±0.5 A)
bipolar power supply optimized
for testing RF and mixed signal
semiconductors.
Valuable rack space is saved, by
providing four bipolar outputs that
eliminates the need for four separate
sources and an external polarity
reversal relay.
The N3280A helps maximize test
system throughput with at least
5 times faster performance than any
previous Agilent dc source. It pro-
vides reduced command processing
time both for setting output levels
and for acquiring measurements.
Plus, any combination of outputs
can be grouped in one programming
command, further reducing test time.
Device current consumption can
easily be measured and character-
ized with the digitizing measurement
system. Each output has its own
16-bit precision voltmeter and
ammeter. Additionally, three current
