N5444A InfiniiMax III 2.92 mm/3.5 mm/SMA Probe Head
The N5444A InfiniiMax III 2.92mm/3.5mm/SMA
probe head provides 30 GHz bandwidth and allows
you to connect two 2.92mm, 3.5mm, or SMA
cables to make a differential measurement on a
single oscilloscope channel.
The N5444A provides for a termination to a
common DC voltage rather than to ground, which
is required for many signal standards. It is
implemented such that from DC to approximately
1 kHz, the termination is 55 Ohms to the
termination voltage, and above approximately
10 kHz, the termination is 50 Ohms to 0.9 times the
termination voltage. The termination voltage range
is ±4V with a minimum step of 5 mV and a
maximum current of 80 mA. The termination
voltage can be controlled internally by the
oscilloscope or applied externally using the supplied DC jack.
