Source and measurement

resolution down to 10 fA

and 100 nV

The Agilent B2900A Series consists of four

models primarily differentiated by number

of channels (one or two) and measurement

and sourcing resolution. The B2901A (single

channel) and B2902A (dual channel) versions

possess 100 fA and 100 nV measurement

resolution and 1 pA and 1 μV sourcing

resolution. The B2911A (single channel) and

B2912A (dual channel) precision versions

possess 10 fA and 100 nV of resolution for

both measurement and sourcing. All members

of the Agilent B2900A Series support popular

banana jack style inputs for cost-effective

and ﬂ exible connectivity; for low-current

measurements below 1 nA, banana jack

to triaxial adapters are available.

Capture transient

phenomena effortlessly

Agilent B2900A Series supports a high speed

sampling measurement function that permits the

capture and display of low frequency transient

phenomena. The Agilent B2901A and B2902A

support a 20 μs (50,000 points/s) sampling rate

and the Agilent B2911A and B2912A support

a 10 μs (100,000 points/s) sampling rate.

Of course, the maximum achievable sampling

rate depends on many factors including signal

level, ambient noise and desired resolution.

4-wire measurement capability

permits accurate low resistance

measurement

When measuring small resistances the innate

cable resistance can create serious measure-

ment error. To solve this, the Agilent B2900A

Series supports a 4-wire (also known as a

remote sense or Kelvin connection) measure-

ment function. In the 4-wire scheme two of

the connectors force current and the other

two connectors measure voltage. Since the

connectors measuring voltage do not have

any current ﬂ owing through them, they can

accurately sense the actual voltage at the DUT.

Measure large capacitive loads

without oscillation

Large capacitive loads can sometimes cause

SMUs to oscillate. To mitigate this, the

B2900A Series supports a high capacitance

measurement mode. The high capacitance

mode enables the measurement of large

capacitive loads without having to worry about

SMU oscillation.

Unmatched bench-top SMU measurement performance

You can make and display accurate low-current measurements

directly on the B2900A front panel.

Roll view mode allows you to capture low-frequency

transient phenomena.
