Using the N2791A 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).
To replace batteries, first slip off
the cover
• 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 (10:1 or 100:1) on the probe via the
attenuation switch and specify the attenuation and probe configuration on
your oscilloscope.
TIP: When measuring signals below 70 V, switch the attenuation ratio to 10:1
in order to obtain a higher resolution signal with less noise. Otherwise set the
attenuation ratio to 100:1.
