P9600A passive voltage probe
As a passive single end probe, the P9600A passive voltage probe has a bandwidth of 600MHz, fixed attenuation
of 10:1 and input impedance of 10 M
Ω
, which supports automatic identification functions. It can be purchased by
users. The option number is 4456-H15.
16.4.1 Operating Instructions
When the P9600A passive voltage probe is used, the input impedance of the oscilloscope is automatically set to
1M
Ω
, the probe type is automatically set to voltage, and the probe attenuation is automatically set to ×10. To
avoid the error caused by the probe connection, the probe should be connected to a probe calibration square wave
signal on the front panel of the oscilloscope, with about 1 kHz frequency and 3 Vpp amplitude, so as to keep flat
amplitude-frequency characteristics of the oscilloscope by adjusting the compensation capacitance of the probe.

The P9600A probe is equipped with accessories for easy testing. Please be familiar with the description of
relevant accessories before use to make better use of this product.
