This VNA is ideal for measuring all kinds of micro-circuits like antennas, attenuators, amplifiers, etc. Its frequency range includes the most popular telecom brands like GSM-GPRS-LTE, Wifi, DECT, GPS, ISM, Zigbee, and Bluetooth.

The VNA software has an integrated Match Circuit Calculator that Calculates a matching circuit from the measurement and simulates this circuit in real-time.

Its small size can also be used near the antenna inside a large device or installation. It’s also ideal for on-site measurements.

The extra Generator port provides an additional signal port that can be used for measuring 3-port devices.

A built-in Bias Generator provides a voltage/current source from -12V to +12V and 100mA. Each of the three ports can be routed to either the bias voltage, ground, or open.

Included in the product are:

  • VNA-0440e
  • PC-software, for controlling, saving data &set-ups, analysis, reporting, etc.
  • Power supply and USB Cable
  • Documentation
  • Carrying case
  • Available accessories include SMA, UFL, and Balanced adapter and calibration kits.

With our VNA Application Programming Interface, the VNA-0440e can be used for automated production testing.
