  • Page 48 Select the instrument's internal measurement range when using CW power sensors or Voltage sensors. The 4530 series uses two widely overlapping ranges for power measurements, and voltage sensors add a third range for very high level signals. Auto is the preferred setting, and should be used in all cases except when the signal makes frequent, large, level transitions, or when the absolute fastest settling is needed after a large power step.

  • Page 144 Making Measurements 4530 Series RF Power Meter Frequency and linearity correction factors for Boonton CW Power Sensors are stored in the sensor adapter, and power measurements can be taken immediately upon inserting the sensor. For best performance, zero the sensor before taking any low-level measurements. A single- or multi-point calibration can be performed if desired to enhance the absolute accuracy of the measurement.

The power is automatically corrected for sensor frequency response, and filtered using user-selectable parameters, then displayed on the front panel readout.

  • Page 147: Pulse Mode

    . For periodic or pulsed signals, it is often necessary to analyze the power for a portion of the waveform, or a certain region of a pulse or pulse burst. For these applications, the 4530 Series has a triggered Pulse Mode. Operation in this mode is similar to a digital storage oscilloscope - power samples are stored in a circular memory buffer until a trigger signal is received.

The shaping error for CW sensors using the FixedCal calibration method is listed in the Boonton Electronics Power Sensor Manual as “Power Linearity Uncertainty”, and depends upon signal level. If the AutoCal calibration method is used with a CW sensor, a fixed value of 1.0% may be used for all signal levels.

    This will reduce certain uncertainty terms, as discussed below. Step 1: The Instrument Uncertainty figure for the 4530 Series is ±0.20%. Since a portion of this figure is meant to include temperature drift of the instrument, and we know an AutoCal has just been performed, we’ll estimate (for lack of more detailed, published information) that the instrument uncertainty is ±0.10%, or half the published figure.
  • Page 160 = ±1.58% Step 9: The Sensor Calfactor Uncertainty is calculated from the uncertainty values in the Boonton Electronics Power Sensor Manual. There is no entry for 10.3GHz, so we’ll have to look at the two closest entries. At 10GHz, the calfactor uncertainty is 5.33%, and at 11GHz it is 4.71%.
  • Page 161 In this example, we will assume that an AutoCal was performed on the sensor earlier in the day, so time and temperature drift may play a role in the uncertainty. Step 1: The Instrument Uncertainty figure for the 4530 Series is ±0.20%. Since it has been a while since AutoCal, we’ll use the published figure.
