Agilent 42941A impedance probe

The 42941A impedance probe enables

in-circuit impedance measurement

of electronic circuits or components.

Grounded devices can also be measured.

Key specifications

Frequency: 40 Hz to 110 MHz

DC BIAS: 0 V to ±40 V

Operation temperature range:

–20 °C to 75 °C

Basic impedance accuracy: ±0.8%

Agilent 42942A terminal adapter

The 42942A terminal adapter con-

verts the four-terminal-pair port con-

figuration to an 7-mm port. This

adapter permits the use of familiar

7-mm test fixtures.

Again, grounded measurement is

available.

Key specifications

Frequency: 40 Hz to 110 MHz

DC bias: 0 V to ±40 V

Operation temperature range:

0 °C to 40 °C

Basic impedance accuracy: ±0.6%

Material test fixtures

Use of a dielectric material fixture

such as the Agilent 16451B or 16452A

allows accurate dielectric material

measurement. Permeability of mag-

netic materials can also be evaluated

with the Agilent 42942A and 16454A

magnetic material test fixture. Auto-

matic measurement and permittivity/

permeability analysis can easily be

performed by using built-in IBASIC

or by I/0 to a computer where the

analysis can be performed.

Other accessories

When a DUT cannot be positioned

near the instrument, a four-terminal-

pair extension (Agilent 16048G: 1 m

or 16048H: 2 m) can be used to extend

the test station to the DUT. These

Agilent extension accessories operate

over the entire frequency and temper-

ature range (40 Hz to 110 MHz, –20 °C

to +150 °C) of the 4294A.
