The N2774A is a wide-band, DC to 50MHz, active current probe. The
probe features low noise and low circuit insertion loss. In conjunction
with the power supply (N2775A), this probe can be used with any
oscilloscope or recorder with a 1 MW input resistance and a BNC
connector.
The N2774A two operating regions that provide a wide, flat frequency
response. In the DC to low frequency AC region, the probe operation is
based on the negative feedback of the amplifier system that includes the
thin film Hall element as a detector. In the high frequency region, the
probe operates as a current transformer.
The N2774A is ideal for acquiring high transient time signals such as
those found in Motor Controllers, in Switching Power Supplies, and in
Current Amplifiers driving inductive loads.
- Flat bandwidth – dc to 50 MHz
- Low noise – <2.5 mA rms
- Low circuit insertion loss
- Can be used with any oscilloscope having a BNC input
Compatible with any scope or voltage measuring instruments with BNC input, the Keysight N2774A is a high bandwidth, active current probe that offers an accurate and reliable solution for measuring dc and ac currents. The probe uses a hybrid technology that includes a Hall effect sensor, which senses the dc current, and a current transformer, which senses the ac current, making it unnecessary to make an electrical connection to the circuit.
- Flat bandwidth – dc to 50 MHz
- Low noise – <2.5 mA rms
- Low circuit insertion loss
- Can be used with any oscilloscope having a high-impedance BNC input
- Companion power supply N2775A (2x 12 Vdc output) lets you connect two N2774As to a single power supply
- Select the 1147A for AutoProbe interface version of 50MHz current probe
