Single-ended Active Probes (Continued)
N7020A power rail probe
– 2-GHz single-ended active probe for power rail noise measurement
– 1.1:1 attenuation ratio ensures low noise signal measurement
– ± 24 V of probe offset range enables effective elimination of DC component of a
power supply.
The N7020A power rail probe is a low noise, large offset range oscilloscope probe that
enables users to measure small signals riding on top of DC power rails.
– Low noise: The N7020A power rail probe is a 1:1 attenuation ratio active probe. As
a general rule, the higher a probes attenuation ratio, the nosier the signal will be on
the oscilloscope.
– Large offset range: The N7020A power rail probe provides ± 24 V of probe offset.
This enables users to center the signal on screen while placing the oscilloscope at
its maximum vertical sensitivity and zoom in on the signal.
– Low DC loading: The N7020A power rail probe has 50 kΩ input impedance at DC,
minimizing the probe’s DC loading of the power rail.
– Large input dynamic range: The N7020A power rail probe’s ± 850 mV input dynamic
range means that users can measure up to ± 850 mV deviations of their DC
supplies. This is very useful for measuring programmable supplies like those used in
microcontroller power saving modes.
– Supporting three connection options — pigtail solder head (2 GHz), SMA (2 GHz),
and browser (350 MHz).
