InfiniiMax III Probe Amplifiers
There are four InfiniiMax III amplifier models:
• N2800A 16 GHz Probe Amplifier
• N2801A 20 GHz Probe Amplifier
• N2802A 25 GHz Probe Amplifier
• N2803A 30 GHz Probe Amplifier
Each probe amplifier is pre-loaded with its specific measured
S-parameters. When used with the Infiniium 90000 X-series, the
oscilloscope downloads these parameters and automatically corrects the
response of the unique probe system.

Menu Button
Press this button to bring up the Probe dialog box in the oscilloscope GUI.
Light Button
Press this button to turn the LED headlights on the browser probe head
on/off. Pressing and holding this button will ramp the intensity of the LED
headlights. You may want to adjust the brightness to accommodate
different lighting or glare conditions.
Sensitivity Indicator
If you are using the ZIF probe head, the sensitivity indicator tells you
which ZIF tip is connected to the probe head. If the N5447A ceramic high
sensitivity ZIF tip is connected then the “Hi” sensitivity LED will be
illuminated. If the N5440A ceramic ZIF tip is connected then the “Normal”
sensitivity LED will be illuminated. This will assist you in ensuring that the
correct ZIF tip is selected in the oscilloscope GUI’s probe dialog box.
