The small form factor and extensive
range of standard probe tips ensures
that this probe can meet any difficult
probing challenge. Various flexible
leads and clips, such as right-angle
leads, Y-adapters, and micro-grabbers,
are also available for probing test
points that are spaced farther apart.
± 8 V input dynamic range,
± 12 V offset range
Engineers must commonly probe
high frequency signals with high
signal fidelity. Typical passive probes
with high input R and C provide good
response at lower frequencies but
inappropriately load the circuit and
distort signals at higher frequencies.
The ZS Series features both high
input R (1 MΩ) and low input C (0.6 pF
and 0.9 pF) to reduce circuit Loading
across the entire probe/oscilloscope
bandwidth. The ZS1000 is ideal
for 200–600 MHz oscilloscopes.
The ZS1500 is ideal for 1 GHz

Innovative Grounding Provides
the Highest Signal Fidelity
Keeping the ground loop short is
critical to eliminating the effect of
high inductance on the signal. The
ZS probes provide a wide variety of
unique and innovative accessories
which maintain the highest signal
fidelity. They eliminate the effects of
the loop on the circuit.
oscilloscopes, the ZS2500 is ideal
for 2 GHz oscilloscopes, and the
ZS4000 is ideal for 2.5 GHz and
4 GHz oscilloscopes.
