  • Page 15 Instrumentation (AR) has addressed this by providing quality power heads to meet virtually all applications. AR offers a family of heads with frequency ranges spanning 10 kHz to 40 GHz and sensitivity from 0.1 nW (-70 dBm) to 25 W (+44 dBm). A choice of diode or thermocouple heads with 50 or 75 ohms impedance in coaxial or waveguide styles are available.
  • Page 16 CALIBRATION AND TRACEABILITY AR employs both a linearity calibration as well as frequency response calibration. This maximizes the performance of diode heads and corrects the non-linearity on all ranges. Linearity calibration can be used to extend the operating range of a diode head. It can also be used to correct non-linearity throughout a head’s dynamic range, either thermocouple or diode.

  • Page 21 2. POWER HEAD CHARACTERISTICS The power head has three primary functions. First the head converts the incident RF or microwave power to an equivalent voltage that can be processed by the power meter. The head must also present to the incident power, an impedance which is closely matched to the transmission system.

  • Page 29 5. PULSED RF POWER PULSED RF POWER OPERATION Although this manual discusses power heads used with average responding power meters, for rectangular pulsed RF signals, pulse power can be calculated from average power if the duty cycle of the reoccurring pulse is known.
  • Page 30 Models PH – Power Heads PULSED RF OPERATION THERMOCOUPLE HEADS Figure 5-2 shows the regions of valid duty cycle and pulse power that apply to the thermal heads. As the duty cycle decreases, the average power decreases for a given pulse power and the noise becomes a limitation. Also, there is a pulse power overload limitation.
  • Page 31 Models PH – Power Heads PULSED RF OPERATION DIODE HEADS Figure 5-3 shows the valid operating region for the diode heads. As with thermal heads, the bottom end measurement is limited by noise, getting worse as the duty cycle decreases. At the top end, the limitation is on pulse power because even a very short pulse will charge up the detecting capacitors.

  • Page 33 This is caused due to the nonlinear response of diode and thermocouple heads at high power levels. AR heads reduce this error through the process of linearity calibration, as discussed earlier, however the "shaping” that is performed is not without error and must be added into total uncertainty.
  • Page 34 The measurement conditions for this example are as follows: The AR Model PM2002 Power Meter will be used with a Model PH2005 Power Head to measure a CW signal. The signal will be at a level of –55 dBm and frequency of 7 GHz. The SWR of the source will be 1.50.
  • Page 35 Models PH – Power Heads 3. At a frequency of 7 GHz a calibration factor will be applied to our measurement. The worst case uncertainty of this calibration factor at 7 GHz is 3.1%; (See Table 3-1). 4. The next item to calculate is mismatch uncertainty. This uncertainty is calculated from the SWR’s of both head and source.
  • Page 36 Sum or Squares Total RSS Uncertainty NOTES: 1. Worst case instrumentation accuracy for the AR RF Power Meters (PM2002) 0.23% at fs 0.46% at 1/10 fs 2. If 50 MHz, 0 dB power reference is used, uncertainty is 1.20% (worst case).
