N7026A high sensitivity clamp-
on current probe
1 mA/div sensitivity
The N7026A is the Keysight’s highest
sensitivity clamp-on current probe. It
has up to 5x lower noise than our other
clamp-on current probes with 0.1V/A
output voltage rate. This enables you to
measure down to 1 mA/div with much
higher accuracy. The N7026A, when
used with an InfiniiVision or Infiniium
oscilloscope, provides highly-accurate,
low current waveforms for improved
debug and analysis.
Wide input range
It also has a wide input range, up to 30
Arms or 40 Apk. To achieve the widest
input range, you must use the external
AC power adapter that comes with
the probe. Without the external power
adapter, you can achieve up to a 5 Arms
or 5 Apeak input range. The oscilloscope
will automatically synchronize with
the corresponding power source when
inserting or removing the AC adapter.
In either case, a degauss operation will
occur.
Degaussing made easy
For accurate measurement with a clamp-on
current probe, degaussing and eliminating
the offset error is critical. A degauss button
is included in the design of this probe. One
push of the button will perform a degauss
operation. Pushing and holding the button for
> 2 sec will perform a degauss and autozero
the DC offset. Whenever you are using the
degauss button, the current sensor should be
locked with no current flowing. Alternatively,
the same operation can be performed from the
oscilloscope GUI.
