High input impedance low noise FET Probe.

The Mathews Engineering FETPROBE1 is an AC coupled, high impedance, RF probe intended for industrial and laboratory use.  This probe has 1X gain from 100 kHz to 1 GHz and works into the 50Ω loads commonly found on RF test & measurement equipment.  Because the probe is AC coupled, DC input impedance is greater than 10 GΩ and AC input impedance is dominated primarily by the parasitic capacitance of the probe tip which is about 3.5 pF.

Key Specifications:

• 100 kHz-1000 MHz Bandwidth
• Input: AC coupled 3.5 pF, spring action "pogo" pins
• High resistance to damage from DC and AC overloads
• Output: 50 Ohms, SMA(m) or BNC(m) with included adapter
• Gain: 1X into 50 ohms
• Very low noise, virtually no spurious
• Operates from 110 VAC
• Full specifications show with product images

Applications:

• Turns any 50 ohm input into a high-Z probe input
• Troubleshoot RF circuits to 1 GHz
• Network analysis (Hi-Z A/B sweeps on 50Ω gear)
• IF Strip Engineering, RF engineering

What's Included:

• FETPROBE1 probe assembly
• 1m (40”) FETPROBE1 combined RF & power cable assembly
• SMA(f) to BNC(m) adapter
• 110 VAC to 9 VDC wall adapter
• User's Manual
