Page 5: Introduction
Keysight N2893A 100 MHz Current Probe User’s Guide Introduction The N2893A is a wide-band, DC to 100 MHz, active current probe. The probe features low noise and low circuit insertion loss. The probe has the following operating regions that provide a wide, flat frequency response. -
Page 6: Inspecting The Probe
- If the shipping container is damaged, or the cushioning materials show signs of stress, notify the carrier as well as your Keysight Technologies Sales Office. Keep the shipping materials for the carrier’s inspection. The Keysight Technologies office will arrange for repair or replacement at Keysight Technologies’... -
Page 7: Safety Information
Do not install substitute parts or perform any unauthorized modification to the instrument. Only WARNING Keysight service centers should perform repair/maintenance on the equipment. To avoid short circuits and accidents that could result in injury or death, use the N2893A probe only DANGER with insulated power lines carrying 300V or less. - Page 8 (mains) power cord. The mains plug shall only be inserted in a socket outlet provided with a protective earth contact. You must not negate the protective action by using an extension cord (power cable) without a protective conductor (grounding). N2893A 100 MHz Current Probe User’s Guide...

Page 9: N2893A Components
Always carry out demagnetizing before measurement. The probe should be connected to the oscilloscope for the demagnetizing process. This process takes about one second. During demagnetizing, a demagnetizing waveform is output. Refer to “Demagnetization and Zero Offset" on page 14 N2893A 100 MHz Current Probe User’s Guide... - Page 10 The probe output sensitivity 0.1 V/A will be automatically selected, as the probe is N OT E plugged into the AutoProbe interface. With a different output sensitivity, accurate measurements are not possible. N2893A 100 MHz Current Probe User’s Guide...

Page 11: Using The Probe
When the probe is connected to a scope channel, the AutoProbe interface recognizes the N OT E probe as an N2893A and automatically configures several settings on the channel to which the probe is connected. N2893A 100 MHz Current Probe User’s Guide... -

- The current direction indicator on the sensor aligns with actual current direction in the insulated conductor. - The sensor opening lever is in the Locked position and the sensor head is properly closed. N2893A 100 MHz Current Probe User’s Guide... - Page 13 When performing continuous measurements, it is necessary to be aware that the zero N OTE offset voltage will drift if the ambient temperature changes. At some frequencies, some sound may be produced by resonance. This has no effect N OT E on measurements. N2893A 100 MHz Current Probe User’s Guide...
