Up to 110 MHz (4-Terminal Pair) Probes
Description: This impedance probe kit is designed for use with the
4294A. It provides the capability to perform in-circuit measurements
(printed circuit patterns, the input/output impedance of circuits,
etc.) with better accuracy and wider impedance coverage from 40 Hz
to 110 MHz. DUTs can be connected by either using the pin probe,
the clip lead (alligator clip adapter) or the BNC adapter. All probe
adapter can be used from 40 Hz to 110 MHz. The pin probe is best
for in-circuit, board-mounted components, The clip lead is for com-
ponents too large for the pin probe. The BNC adapter is used to con-
nect circuits or networks equipped with BNC connectors.
Applicable Instrument: 4294A
Frequency: 40 Hz to 110 MHz
Maximum Voltage: ±42 V peak max. (AC+DC)
Operating Temperature: -20°C to +75°C (probe only)
Furnished Accessories:
Compensation and Measurement: Adapter setup and compensation
is required before measurement. In the Adapter setup menu, select
PROBE 42941A. Use the furnished 3.5 mm short and load standards.
The open condition can be created by not connecting the probe to
anything. Perform phase compensation, short and load data mea-
surements. For compensation, open and short compensation is rec-
ommended. Short compensation is performed by shorting the probe.
To short the probe it is recommended to use a shorting device with
gold-plated surfacing (which provides stable contact resistance).
