Automated Antenna SWR Analyzer

This i s my portable use Analyzer 😉

Main FEATURES

• Mini size: 9.1*5.3*2.5cm
• Net Weight:220g (now you can easily grab it without feeling much weight!)
• Built-in with 3.7V Li-Ion battery (rechargeable)

Hardware:

• Precise and self-calibrating reflectometer design measures forward and reflected signals and impedance data
• Display 2×16 with optional backlight
• Precision DDS signal generator (AD9851) used as signal source
• USB port connects to PC for field-upgradeable software and uploading of real-time measurement data
• With Buzzer

Operations:

• Manual control option displays SWR and complex impedance at selected frequencies
• Automatic scanning results displayed as frequencies of lowest SWR and complex impedance
• Battery operated for field use or use external 13.8V wall adaptor
• Power saving modes
• Multi-point calibration for better accuracy

Capabilities of the device:

• Measure antenna electrical parameters: SWR, impedance (resistance + reactance), capacitance, inductance
• Measure feedpoint impedance
• Measure ground loss
• Adjust antenna tuners and determine loss
• Measure inductors and capacitors
• Measure coax transmission line (SWR, length, velocity factor, approximate Q and loss, resonant frequency, and impedance)
• Measure and determine optimum settings for tuning stubs: SWR, approximate Q, resonant frequency, bandwidth, impedance
• Determine characteristic impedance of transmission line
• Determine length of 1/4 and 1/2 wave phasing lines
• Coaxial Cable Loss
• Determine antenna tuner loss
• Measure balun loss
• Measure inductor Q
• Estimate quartz crystal parameters
• Measure magnetic loop resonance and SWR

• External power: 2.1mm Power Jack (center pin positive)

The Mini60 will probably be comparable to the SARK100
