Using The N2891A High-Voltage Differential Probe - Keysight N2791A User Manual

Using the appropriate probe accessories, connect the inputs to the circuit
under test.
To protect against electrical shock, use only the accessories supplied with
this probe or in the accessory kit.
!
This probe is to carry out differential measurements between two points on
!
the circuit under test. This probe is not for electrically insulating the circuit
under test and the measuring instrument.

Using the N2891A High-Voltage Differential Probe

• To use this probe, first insert the four AA batteries into the probe or connect
the USB power cord to the probe and a USB port (see page 4 to see where
the USB power cord input is located on the probe).
• Then connect the BNC output connector to the channel input of the
oscilloscope. The oscilloscope must have a ground referenced.
• Select the proper attenuation ratio (100:1 or 1000:1) on the probe via the
attenuation switch (see the picture on page 4) and specify the attenuation
and probe configuration on your oscilloscope.
TIP: When measuring signals below 700 V, switch the attenuation ratio to
100:1 in order to obtain a higher resolution signal with less noise. Otherwise
set the attenuation ratio to 1000:1.
• Using the appropriate probe accessories, connect the inputs to the circuit
