N5444A InfiniiMax III 2.92 mm / 3.5 mm / SMA Probe Head

The N5444A InfiniiMax III 2.92 mm/3.5 mm/SMA probe head provides 30 GHz bandwidth
and allows you to connect two 2.92 mm, 3.5 mm, 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.

N5448B Coaxial Phase Matched Cable Pair
For extending the cable length of the N5444A InfiniiMax III probe head and add flexibility
and convenience to the probing setup, you can order N5448B 10 inches (25 cm) long
coaxial phase matched cable pair. This cable pair supports 2.92 mm male-to-2.92 mm
male connection.

Before connecting these cables to the N5444A probe head, you must first remove the
supplied rigid cables of the N5444A probe head.
