Octiv Mono 2.0

OCTIV Mono 2.0 is a through-line RF Wattmeter, directional power sensor and impedance analyser. It measures a single fundamental frequency and it has a NIST traceable full scale accuracy of 1%. Its is a non-intrusive, in-line sensor used to verify RF power output from RF generators, match unit impedance range and efficiency and for general purpose power meter measurements. It can be used as a stand-alone instrument with our state of-the-art software suite or integrated directly with any software platform using one of our advanced communication protocols. There is a solution for every RF application including CW, pulsed and frequency tuning.

Key Features
Auto-switching between CW and Pulsed RF monitoring in time average mode (TAM).
Reports pulse frequency and duty cycle with sub-microsecond precision in TAM.
Integrates over pulse profile for accurate average power and impedance measurement.
Time-resolved mode with 1 microsecond resolution for detailed pulse waveform analysis.
Pulse-trend mode to monitor a number of points within the pulse profile, with 1 microsecond gate times.
RF Frequency tracking band of ±10% around the fundamental frequency.
USB, Ethernet, EtherCAT and Serial communication protocols with easy to use APIs for Integration
Key Benefits
Five fundamental frequencies on a single sensor, saving cost.
Thin profile model (24 mm) available for match unit integration.
Achieve in-line accuracy specifications comparable to expensive offline vector network analysers for precise match unit or plasma chamber characterisation.
Data report rates of up to 500 Samples/second as standard (USB).
With the advanced pulse features, real-time in-pulse matching is now achievable.
Advanced harmonic rejection ensures accurate power measurement at the selected frequency only.
Calibrated up to 80°C to compensate for temperature variation.

Compatible with all QC connectors. Capable of being changed in the field, allowing the unit to be moved between chambers with different connectors if desired.
