1 Purpose

This procedure allows to verify the peak power emitted by the amplifier.


2 Remarks

Attention, this procedure includes measurements of high power radiation. Experience and careful handling is absolutely necessary!


3 Material

  • Peak power meter with sensor head
  • Directional coupler (peak power = 10 kW, average power = 200 W, bandwith = .95 - 2 GHz or equivalent)
  • Attenuators (peak power = 5 kW, average power = 10 W, attenation 20 dB or equivalent)


4 Procedure

  1. Stop acquisition.
  2. Configure a one-measurement (vertical) wind cycle with an IPP of 1000 μs and a pulse width of 2500 ns and pulse code = 0
  3. Calibrate the peak power meter and the probe
  4. Insert the directional coupler between the amplifier output and the circulator (Media:PicturePowerDegreane.png)
  5. Add sufficiently attenuators coupling output of the coupler and the peak power meter
  6. Start acquisition
  7. Measure the emitted peak power taking into account the total attenuation
