Boonton 4540 Series RF Power Meter 3.5 Calibration Before any pulse measurements can be acquired with the 4540 Series, a peak power sensor must be connected from the instrument to the built-in or external calibrator, and calibrated. Making measurements with a CW sensor can be accomplished without calibration. However, it is recommended that autocalibration be performed for optimal performance for CW sensors as well. RF voltage probes do not require autocalibration.
Boonton 4540 Series RF Power Meter STEP 1. PROCEDURE Select the Calibration menu soft key. Initiate autocalibration by selecting AutoCal > Start. The AutoCal routine will calibrate the entire dynamic range of the sensor in approximately 1.5 minutes while reporting status via a dialog box. Figure 3-4 Autocalibration screen. Note 2. You can access the calibration menus directly using the Cal/Zero key. Pressing the key repeatedly will cycle between each channel’s calibration menu.
Boonton 4540 Series RF Power Meter Figure 3-5.
Boonton 4540 Series RF Power Meter 3.6 Making Measurements What you need to know To perform accurate measurements, the following is a minimum list of things you should know about the signal that you wish to measure. Signal frequency - The center frequency of the carrier must be known to allow sensor frequency response compensation. Modulation Bandwidth - If the signal is modulated, know the type of modulation and its bandwidth.
Boonton 4540 Series RF Power Meter 3.6.2 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 4540 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.
Boonton 4540 Series RF Power Meter 3.6.3 Statistical Mode Certain signals are completely random and provide no event that can serve as a trigger for measurements. CDMA or OFDM are common examples. The 4540 Series Statistical Mode was designed to provide measurements for these type of signals. Statistical Mode is only effective when a peak power sensor is connected to the 4540. It is the best choice for analyzing ―noise-like‖ signals that are modulated in a random, non periodic fashion.
Boonton 4540 Series RF Power Meter Note that this analysis does not depend upon any particular test signal, or upon synchronization with the modulating signal. In fact, the analysis can be done using actual communication system signals. Normal operation is not disturbed by the need to inject special test signals.
Boonton 4540 Series RF Power Meter 4. Operation This section presents the control menus and procedures for operating the 4540 Series in the manual mode. All the display menus that control the instrument are illustrated and accompanied by instructions for using each menu item. Note Before any pulse measurements can be acquired with the 4540 Series, a peak power sensor must be connected from the instrument to the built-in or external calibrator, and calibrated.
Boonton 4540 Series RF Power Meter 4.3 Numerical Data Entry Many 4540 Series parameters can be entered directly from the numeric keypad. In some cases, such as the frequency of the measured signal, keypad entry is necessary. In this example, the following menu path is used. Channel > Channel1 > Extensions Pg 2 > Frequency 1. Assume the frequency is initially set to 1.000 GHz. In this case "1.000 GHz" will appear in the menu box under "Frequency". Further, assume the actual measurement frequency is 578.
Boonton 4540 Series RF Power Meter 4.4 Sensor Calibration The Model 4540 Series features a built-in AutoCal process that automatically calibrates the Peak Power sensors for all measurement modes, and also calibrates most CW Power sensors for the modulated measurement mode. An internal programmable 50 MHz calibrator outputs discrete incremental power levels covering the dynamic range of the sensor. Zeroing is part of the AutoCal process and is adjusted for the High and Low video bandwidths where applicable.

Boonton 4540 Series RF Power Meter 6. Application Notes This section provides supplementary material to enhance your knowledge of the 4540 Series' advanced features and measurement accuracy. Topics covered in this section include pulse measurement fundamentals, automatic measurement principles, and an analysis of measurement accuracy. 6.1 Pulse Measurements 6.1.1 Measurements Fundamentals The following is a brief review of power measurement fundamentals. Unmodulated Carrier Power.
Boonton 4540 Series RF Power Meter Figure 6-1. Pulsed RF Signal Figure 6-2. Distorted Pulse Signal Peak Power. The 4540 Series instruments make power measurements in a manner that overcomes the limitations of the pulse power method and provides both peak power and average power readings for all types of modulated carriers.
Boonton 4540 Series RF Power Meter 6.1.2 Diode Detection Wideband diode detectors are the dominant power sensing device used to measure pulsed RF signals. However, several diode characteristics must be compensated to make meaningful measurements. These include the detector’s nonlinear amplitude response, temperature sensitivity, and frequency response characteristic. Additional potential error sources include detector mismatch, signal harmonics and noise. Detector Response.
Boonton 4540 Series RF Power Meter Frequency Response. The carrier frequency response of a diode detector is determined mostly by the diode junction capacitance and the device lead inductances. Accordingly, the frequency response will vary from detector to detector and cannot be compensated readily. Power measurements must be corrected by constructing a frequency response calibration table for each detector. Mismatch.
Boonton 4540 Series RF Power Meter 6.2 Pulse Definitions IEEE Std 194™-1977 Standard Pulse Terms and Definitions ―provides fundamental definitions for general use in time domain pulse technology‖. Several key terms defined in the standard are reproduced in this subsection, which also defines the terms appearing in the 4540 Series text mode display of automatic measurement results. 6.2.1 Standard IEEE Pulse The key terms defined by the IEEE standard are abstracted and summarized below.
Boonton 4540 Series RF Power Meter Table 6-1. Pulse Terms TERM DEFINITION Base Line The two portions of a pulse waveform which represent the first nominal state from which a pulse departs and to which it ultimately returns. Top Line The portion of a pulse waveform which represents the second nominal state of a pulse. First Transition The major transition of a pulse waveform between the base line and the top line (commonly called the rising edge).
Boonton 4540 Series RF Power Meter 6.3.2 Automatic Measurement Terms The following terms appear in the 4540 Series Text display in the Pulse mode. The Text column lists the abbreviated forms that appear on the display screen. Table 6-2. Automatic Measurement Terms Text TERM DEFINITION Width Pulse Width The interval between the first and second signal crossings of the mesial line.
Boonton 4540 Series RF Power Meter 6.3.3 Automatic Measurement Sequence The automatic measurement process analyzes the captured signal data in the following sequence: 1. Approximately 500 samples of the waveform (equivalent to one screen width) are scanned to determine the maximum and minimum sample amplitudes. 2. The difference between the maximum and minimum sample values is calculated and stored as the Signal Amplitude. 3.
Boonton 4540 Series RF Power Meter 7. The process locates the bottom amplitude (baseline) using the IEEE histogram method. A histogram is generated for all samples in the lowest 12.8 dB range of sample values. The range is subdivided into 64 power levels of 0.2 dB each. The histogram is scanned to locate the power level with the maximum number of crossings. This level is designated the baseline amplitude. If two or more power value have equal counts, the lowest is selected. 8.

Boonton 4540 Series RF Power Meter 6.5 Measurement Accuracy The 4540 Series includes a precision, internal, 50 MHz RF reference calibrator that is traceable to the National Institute for Standards and Technology (NIST). When the instrument is maintained according to the factory recommended one year calibration cycle, the calibrator enables you to make highly precise measurements of CW and modulated signals.
Boonton 4540 Series RF Power Meter The worst case approach is a very conservative method in which the extreme conditions of each of the individual uncertainties are added together. If the individual uncertainties are all independent of one another, the probability of all being at their worst-case conditions simultaneously is extremely small. For this reason, the uncertainties are more commonly combined using the RSS method.
Boonton 4540 Series RF Power Meter 6-18 Application Notes
Boonton 4540 Series RF Power Meter The value to use for calibration level uncertainty depends upon the sensor calibration technique used. If AutoCal was performed, the calibrator’s uncertainty at the measurement power level should be used. For sensors calibrated with FixedCal, the calibrator is only used as a single-level source, and you should use the calibrator’s uncertainty at the FixedCal level, (0dBm, for most sensors).
Boonton 4540 Series RF Power Meter Sensor Temperature Coefficient. This term is the error which occurs when the sensor’s temperature has changed significantly from the temperature at which the sensor was AutoCal’d. This condition is detected by the Series 4540 and a ―temperature drift‖ message warns the operator to recalibrate the sensor for drift exceeding ±4C on nontemperature compensated peak sensors.
Boonton 4540 Series RF Power Meter The sensor calfactor uncertainty is due to uncertainties encountered while performing this frequency calibration (due to both standards uncertainty, and measurement uncertainty), and is different for each frequency. Both worst case and RSS uncertainties are provided for the frequency range covered by each sensor, and are listed on the sensor datasheet and in the Boonton Electronics Power Sensor Manual.
Boonton 4540 Series RF Power Meter Step 4: The Source Mismatch Uncertainty is calculated using the formula in the previous section, using the DUT’s specification for ρSRCE and calculating the value ρSNSR from the SWR specification on the 51075’s datasheet. ρSRCE = 0.20 (source reflection coefficient at 10.3GHz) ρSNSR = (1.40 - 1) / (1.40 + 1) = 0.167 (calculate reflection coefficient of 51075, max SWR = 1.40 at 10.3GHz) USourceMismatch = ±2 × ρSRCE × ρSNSR × 100 % = ±2 × 0.20 × 0.167 × 100 % = ±6.
Boonton 4540 Series RF Power Meter Step 10: Now that each of the individual uncertainty terms has been determined, we can combine them to calculate the worstcase and RSS uncertainty values: U (±%) K (U×K)2 ( %2 ) 1. instrument uncertainty 0.10 0.500 0.0025 2. calibrator level uncertainty 2.45 0.577 1.9984 3. calibrator mismatch uncertainty 0.34 0.707 0.0578 4. source mismatch uncertainty 6.68 0.707 22.305 5. sensor shaping error uncertainty 1.00 0.577 0.3333 6. sensor temperature drift uncertainty 0.00 0.
Boonton 4540 Series RF Power Meter Step 2: The Calibrator Level Uncertainty for the Model 2530 External 1GHz calibrator may be calculated from the calibrator’s specification. The 0dBm uncertainty is 0.065dB, or 1.51%. To this figure, we must add 0.03dB or 0.69% per 5dB step from 0dBm. 13dBm is 2.6 5dB steps (13/5) away from 0dBm. Any fraction must always be rounded to the next highest whole number, so we’re 3 steps away. UCalLevel = ±(1.51% + (3 × 0.69%)) = ±3.
Boonton 4540 Series RF Power Meter Step 9: The Sensor Calfactor Uncertainty needs to be interpolated from the uncertainty values in the Boonton Electronics Power Sensor Manual. At 1 GHz, the sensor’s calfactor uncertainty is 2.23%, and at 0.5GHz it is 1.99%. Note, however, that we are performing our AutoCal at a frequency of 1GHz, which is very close to the measurement frequency. This means that the calfactor uncertainty cancels to zero at 1GHz, as discussed in the previous section.
