High-Frequency Voltage Probes Overview
Active voltage probes contain an
active component, usually a field-
effect transistor (FET), and there-
fore need to be powered. A FET
input has the advantage of pro-
viding a very low input capaci-
tance, typically from less than
1 pF to a few pF. This low capaci-
tance results in a high input
impedance on frequencies up to
7 GHz. With such low loading,
active probes can be used on
high-impedance circuits that
would be seriously loaded by
passive probes.
New InfiniiMax probe family.
The innovative InfiniiMax probe
system provides either differential-
or single-ended probing solutions
for the most demanding connec-
tion requirements, without sacri-
ficing performance.

High-Frequency Probe Advantages
Timing and voltage measurements more accurate at
high bandwidths
Resistive divider probes cost less than active probes
Active probes are least intrusive to circuit under test,
high input resistance

Resistive divider
Resistive divider
Resistive divider probes are
passive probes. They feature low
capacitive loading and accurate
timing measurements with high-
bandwidth signals at a much
lower cost than active probes.

Limitations
Active probes are more expensive than general purpose passive probes
Relatively heavy resistive loading with resistive divider probes
Active probes have lower dynamic range, lower maximum voltage and
are less rugged compared to passive probes
