Specifications

TheAgilentB2961A/B2962A
6.5 Digit Low Noise Power Source
are a new generation of power
supply/sources offering 6.5 digit
best-in-class precision, wide bipolar
output ranges of 100 nV-210 A &
10 fA-10.5 A, and an extremely
low noise floor of 10 µVrms and
1 nVrms/√Hz (at 10 kHz). It also
offers innovative features such as
graphing capability and arbitrary
waveform generation capability
(1 mHz-10 kHz), which enable tests
and evaluation that conventional
power supply/sources cannot do.
ThesefeaturesmaketheB2961A/
B2962Aidealcompanionsources
to use with other instruments such
as oscilloscopes, network analyzers,
spectrum analyzers, frequency
counters, digital multi meters,
nano-voltmeters, etc. The advanced
featuresoftheB2961A/B2962A
provide researchers, electronic
development engineers and elec-
tronic technicians with the tools
that they need to meet their most
difficult measurement challenges.
One area where power supply
sourcing resolution is important is
analog-to-digital converter (ADC)
evaluation. For an 8-bit ADC, a 1 V
(peak to peak) signal would have
a minimum step voltage of 3.9 mV.
In this case a power source with
4.5 digit resolution is sufficient
to use for the DC input voltage.
However, for an ADC with 14-bits
or more, 4.5 digit resolution is not
enough.InthiscasetheB2961A/
B2962A’sbest-in-class6.5-digit
sourcing resolution is required
in order to properly evaluate
the ADC circuit.
