APO33
AP034
DIFFERENTIAL PROBES
High bandwidth, excellent common-mode rejection ratio (CMRR) and low noise make
these active differential probes ideal for applications such as disk drive design and
failure analysis, as well as wireless and data communication design. With the ProBus
interface, the AP034 and AP033 become an integral part of the oscilloscope, allowing
sensitivity, offset and common-mode range to be displayed on the scope screen.
Common mode sensing and input protection capabilities of the AP033 add additional
functionality.
Features for both probes:
• 500 MHz (AP033) and 1 GHz (AP034) bandwidths
• x10 gain to ÷ 10 attenuation range (AP033)
• 10,000:1 DC CMRR
• Low 9 nV/√Hz noise (AP033)
• 1.5 pF/side input C (AP034)
• 200 µV/div (AP033)
• Input ESD protection
• Autozero feature
