7037 Series

0.5% Accurate Precision CW & Pulse Power Sensors

Superb Accuracy!

The 7037 Series in-line RF Power Sensor brings first-to-market, traceable measurement accuracy to applications requiring precise RF power measurement, such as in the semiconductor, medical and laser industries. Bird's advanced CW & Pulse sensors, minimize RF process variability, improve plasma chamber-to-chamber matching and provide critical insight in your RF delivery system.

Highest Accuracy Across the Operating Range
With Bird's cutting-edge, calibration technology, 0.5% accuracy is guaranteed across the dynamic range, ensuring unit-to-unit repeatability and reducing process variability.

CW & Pulse Power Measurements without Switching Modes
Regardless of whether you are using CW or Pulsed RF, both measurements are automatically displayed using Bird’s power meter without the need for switching modes.

Multilevel Pulse Measurements
Customize your complex process recipe measurements with up to 4 intervals within each pulse.

  • Time Domain Display
  • NIST traceable calibration
  • Harmonic filtering
  • External sync input
  • RF Interlock (optional)
  • Programmable with SCPI command set
  • With RF generator calibration and verification, these high-accuracy sensors deliver confidence in the RF generator output.
  • Use the VPM3 to log and analyze the RF power data from experimental recipes for more streamlined process development.
  • In-situ processes monitoring allows for real time monitoring of processes at runtime to detect anomalies.
  • Time domain analysis of RF pulse waveforms provide a closer look at high power RF pulses.

  • The Pulse Power Sensor can measure 4 states within a single pulse.
  • Depending on the rep rate, the minimum state width is approximately 1% of the pulse rep rate period.
  • Depending on the rep rate, the maximum state width is approximately 99% of the pulse rep rate period.
  • For applications with rep rates near the low or high extremes of the spec, consult the user manual for the exact limits.
