1147B 50-MHz current probe with AutoProbe
interface
1146B 100-kHz current probe
N2893A 100-MHz current probe with
AutoProbe interface
N2780B Series current probes with N2779A
power supply
N2780B/81B/82B/83B/83L
2-MHz/10-MHz/50-MHz/100-
MHz current probes
The N2780B Series current probes are
high bandwidth, active current probes,
featuring flat bandwidth, low noise
(2.5 mArms) and low circuit insertion
loss. In conjunction with the power supply
(model N2779A), these probes can be
used with any oscilloscope having a high-
impedance BNC input. The companion
power supply N2779A (3 x 12 Vdc output)
lets you connect up to any three N2780B-
83B current probes to a single power
supply.
The N2783L 80 MHz current probe
offers a 5-m long cable, which allows
you to reach DUTs over long distances
very easily. Other than the bandwidth
performance, the N2783A and N2783L
have the same electrical performance.
The N2783L also requires the N2779A
power supply to power the probe.
1147B/N2893A/N7026A
50-MHz/100-MHz/150-MHz
current probe with AutoProbe
interface
The 1147B/N2893A/N7026A have
wide bandwidth ranges, from DC to
50-MHz/100-MHz/150-MHz. The probes
offer flat frequency response across the
entire bandwidth range, low noise (2.5
mArms for 1147B/N2893A, 250 µArms for
N7026A) and low circuit insertion loss.
These three current probes are
compatible with the AutoProbe interface,
which completely configures the
oscilloscope for the probe. AutoProbe can
be found on the InfiniiVision 3000T X-,
4000 X-, and 6000 X-Series. Probe power
is provided by the scope. The N2893A
and N7026A uniquely provide auto
demagnetization and offset elimination
feature when used in conjunction with
InfiniiVision or Infiniium oscilloscopes.
– Up to 150 MHz bandwidth and
500 Arms current measurement range
– Hybrid technology to measure ac and
dc
– Compatible with 1 MΩ scope input
Accurate current measurements
without breaking the circuit
Compatible with any scope or voltage
measuring instruments with BNC input, the
1146B and N2780B Series current probes
offer accurate and reliable solutions
for measuring dc and ac currents. The
probes use a hybrid technology that
includes a Hall effect sensor that senses
the dc current, and a current transformer
that senses the ac current, making
it unnecessary to make an electrical
connection to the circuit.
1146B 100 kHz current probe
The 1146B ac/dc current probe provides
accurate display and measurement of
currents from 100 mA to 100 Arms, dc to
100 kHz, without breaking into the circuit.
A battery level indicator and overload
indicator help ensure proper readings. It
connects directly to the scope through a
2-m coaxial cable with an insulated BNC.
