HP (Agilent) 5347A 20 GHz

Microwave Counter / Power Meter


Equipment Notes:

This instrument combines a microwave frequency counter and RF Power Meter.  The counter will cover 10 Hz to 20 GHz frequency range.  The Power meter range is dependent on the sensor chosen.  The unit works with most, if not all of the 848x series sensors. 

  • Original Manual is included but not in the photos. 

  • 11730a Power Sensor Cable is included but no power sensors are included in auction.

  • Option 006 Microwave Level Limiter.

  • Option 011 HP-IB Interface.

We ran this instrument through its paces in our lab.  It performs flawlessly and is in excellent physical condition.

MRSP - With options was over $10,000.00
