Input voltage range: 2.5 Vrms

Input common-mode range: ±12 V DC ( at 250 Hz) (maximum input voltage must not be exceeded)

The N5444A Infiniimax III 2.92 mm/3.5 mm/SMA probe provides 28 GHz bandwidth and allows you to connect two 2.92 mm, 3.5 mm, or SMA cables to make differential measurements on a single oscilloscope channel.

Order the N5448B 2.92 mm Probe Flex Cable (10” or 25 cm long) to extend the cable length for added convenience. Compatible with all InfiniiMax III probe amplifiers.

The N5444A provides termination to common DC voltages instead of ground, which is a requirement of many signaling standards. This is accomplished by terminating 55 Ω to the termination voltage from DC to ~1kHz and 50 Ω to 0.9 times the termination voltage above ~10 kHz. Termination voltage range is ±4 V (minimum step size: 5 mV) and maximum current is 80 mA. The terminal voltage can be controlled internally by the oscilloscope or applied externally using the provided DC jack.

For engineers designing and debugging the latest interface standards, the N5444A InfiniiMax III probe offers the highest accuracy and signal integrity in the industry.
