S11 measurements: antennas and RF circuits

The S11 port allows the signal reflection from the connected device to be analysed. This measurement is particularly useful for tuning antennas and impedance matching networks.

• ROS / SWR / VSWR measurement.
• Return loss measurement.
• Reflection coefficient measurement.
• Complex impedance measurement.
• Resistance display.
• Reactance display.
• Determining the resonance frequency of an antenna.
• Design of impedance matching networks.
• Analysis of antenna matching over a wide frequency range.

S21 measurements: filters, cables and RF circuits

The S21 measurement determines how a signal passes through an RF device. It is used in particular to characterise filters, coaxial cables, attenuators and other passive components.

• Measurement of insertion loss.
• Measurement of transmission between the two ports.
• Analysis of a filter’s frequency response.
• Measurement of bandwidth.
• Measurement of a filter’s rejection.
• Analysis of the amplitude response.
• Analysis of the phase response.
• Measurement of losses in a coaxial cable.
• Characterisation of passive RF components.

Available displays

Results can be displayed in various formats depending on the type of measurement performed.

• LOGMAG: logarithmic magnitude.
• PHASE: signal phase.
• DELAY: group delay.
• SMITH: Smith chart.
• SWR: standing wave ratio.
• POLAR: polar representation.
• LINEAR: linear magnitude.
• REAL: real part.
• IMAG: imaginary part.
• RESISTANCE: resistance.
• REACTANCE: reactance.

Time-domain analysis: TDR and DTF

The LiteVNA 67 can utilise measurements taken in the frequency domain to obtain a representation in the time domain using an IFFT transformation.

This function enables, in particular, TDR (Time Domain Reflectometry) and DTF (Distance To Fault) analyses to be carried out.

• Fault detection on a coaxial cable.
• Approximate location of an impedance discontinuity.
• Detection of a faulty connector.
• Detection of a mismatch on a line.
• Estimating the distance to a fault.
• Adjustment of the cable velocity factor to convert propagation time into distance.

Integrated source attenuator

The LiteVNA 67 features a built-in source attenuator. This function allows the user to control and reduce the level of the signal injected into the device under test.

It can be particularly useful when characterising certain active circuits, such as amplifiers or mixers, to prevent them from being subjected to excessively high RF levels.

Warning: the source attenuator acts on the signal generated by the LiteVNA. It does not protect the measurement input from excessive RF power originating from the device under test.

The maximum permissible level at the input of the LiteVNA 67 is +10 dBm. The instrument must therefore never be connected directly to the RF output of a transmitter or power amplifier without using appropriate attenuation and protection.

Large 7-inch capacitive touchscreen

The large 7-inch touchscreen is one of the key improvements in the LiteVNA 67 compared to the more compact LiteVNA models.

It makes it easier to read curves, markers and Smith charts directly on the unit, without always needing to connect to a computer.

This size is particularly useful for use on a workbench, in a laboratory, during the maintenance of radio installations or for antenna tuning in the field.

Type N RF connectors

Both RF ports on the LiteVNA 67 use Type N connectors.

Compared to the SMA connectors on the LiteVNA 62 and LiteVNA 64, N-type connectors offer a more robust connection and are particularly well-suited to regular use with test leads and RF equipment.

Adapters can be used to take measurements on equipment fitted with SMA, BNC, UHF/PL, TNC or other RF connectors.

USB-C connection to computers and Android devices

The LiteVNA 67 can operate independently via its touchscreen, but it can also be connected to a computer or an Android device via its USB-C interface.

Using NanoVNA/LiteVNA-compatible software makes it easier to record and analyse measurements, work on long sweep sequences and carry out additional analyses.

• Connection to a PC via USB-C.
• Can be connected to a compatible Android device.
• Recording of measurements.
• Post-processing of waveforms.
• Use of up to 65,535 sweep points via USB.

Storage on a microSD card

The LiteVNA 67 also features a microSD card slot, allowing you to save data and screenshots directly from the device.
