1X gain into 50 Ohms
2X gain into high-Z
High input impedance low noise buffer amplifier.
  • DC-400 MHz Bandwidth
  • Input: 1 Megaohm, 4 pF, BNC(f) 
  • DC Input resistance can be increased to up to 500 GigaOhms by removing R3, internal 1 MOhm resistor (charge amplifier)
  • Output: 50 Ohms, Type N(f)
  • Gain: 1X into 50 ohms or 2X into 1 MOhm
  • Works by itself or with 10X or 100X scope probes (not included)
  • Solid billet construction, durable black wrinkle powder coat
  • Ultra low noise, virtually no spurious
  • Operates from batteries, 120 VAC, or USB power
  • 6 hour battery life (3 x AAA alkaline)
  • Unambiguous ON/OFF power LED indicates "in specification" operation
  • Full specification table shown in product images
Applications:
  • Allows the use of oscilloscope probes with 50 ohm test equipment
  • Turns any 50 ohm input into a 1 MOhm oscilloscope type input
  • Allows remote use of scope probes in hard to reach places (output will drive a lengthy 50 ohm transmission line)
  • Signal distribution and monitoring (drive oscilloscope, frequency counter, and spectrum analyzer simultaneously)
  • Network analysis (Hi-Z A/B sweeps)
  • Control system stability analysis
  • IF Strip Engineering, RF engineering
What's Included:
