ProBus Interface
Large Offset Range
Permits the DC signal to be
displayed in the vertical center of the
oscilloscope grid with a high-sensitivity
gain setting.
Low Attenuation and Noise
The probe attenuation is a nominal
1.2x coupled to the oscilloscope at
DC50 Ω. This keeps additive noise to a
minimum, and makes it exceptionally
useful with High Denition
oscilloscopes for lowest noise at
highest sensitivity gain settings.
High DC Input Impedance
50 kΩ input impedance at DC
effectively eliminates probe loading on
the DC power/voltage rail and provides
for more accurate measurements and
signal delity.
4 GHz of Bandwidth
Provides maximum bandwidth
for probing near the CPU, and the
perfect match with the 4 GHz, 10 bit
HDO9404 when making power integrity
measurements.
Wide Assortment of
Tips and Leads
The RP4030 is supplied standard with
solder-in and coaxial cables with MCX
and U.FL PCB receptacle mounts. A
browser tip is optionally available.
Additional receptacles or leads may
be purchased as accessories and
left connected in circuit for easy
connection of different signals during
different test or validation stages.
The RP4030 is designed specically to probe a 50Ω DC power/voltage
rail. The probe has large built-in offset, low attenuation (noise), and
high DC input impedance. Built-in offset and low attenuation permit
the power/voltage rail to be offset in the oscilloscope by its mean DC
voltage with high oscilloscope gain (sensitivity) to achieve a noise-free
view of small signal variations. The high DC input impedance eliminates
loading of the DC rail.
