Introduction

1-1 Overview

1-2 Sensor T rade-offs

1

The overall performance of a power meter is dependent upon the sensor employed.
Boonton Electronics (Boonton) has addressed this by providing quality power sensors
to meet virtually all applications. Boonton offers a family of sensors with frequency
ranges spanning 10 kHz to 100 GHz and sensitivity from 0.1 nW (-70 dBm) to 25 W (+44
dBm). A choice of Diode or Thermocouple Sensors with 50 or 75 ohms impedances in
Coaxial or W aveguide styles are available.

Both the Thermocouple and Diode Sensors offer unique advantages and limitations.
Thermocouple Sensors measure true RMS power over a dynamic range from 1.0 µW (-30
dBm) to 100 mW (+20 dBm), and therefore, are less sensitive to non-sinusoidal signals
and those signals with high harmonic content. The Thermocouple Sensors also provide
advantages when making pulsed RF measurements with extremely high crest factors.
While the headroom (the difference between the rated maximum input power and burnout
level) for CW (continuous wave) measurements is only a few dB (decibels), Thermocouple
Sensors are very rugged in terms of short duration overload. For example, a sensor that
operates up to 100 mW average power (CW) can handle pulses up to 15 watts for
approximately two microseconds. One of the major limitations to the Thermocouple
Sensor is on the low-end sensitivity. Low-end sensitivity of these sensors is limited by
the efficiency of the thermal conversion. For this reason, the Diode Sensor is used for
requirements below 10 µW (-20 dBm).

CW Diode Sensors provide the best available sensitivity , typically down to 0.1 nW (­70 dBm). Boonton Diode Sensors are constructed using balanced diode detectors. The
dual diode configuration offers increased sensitivity as well as harmonic suppression
when compared to a single diode sensor. The only significant drawback to Diode
Sensors is that above the level of approximately 10 µW (-20 dBm), the diodes begin to
deviate substantially from square-law detection. In this region of 10 µW (-20 dBm) to
100 mW (20 dBm), peak detection is predominant and the measurement error due to the
presence of signal harmonics is increased.

The square-law response can be seen in Figure 1-1, where a 100% amplitude modulated
signal is shown to have virtually no effect on the measured power at low levels. Of
course, frequency modulated and phase modulated signals can be measured at any
level, since the envelope of these modulated signals is flat. Frequency shift keyed and
quadrature modulated signals also have flat envelopes and can be measured at any
power level.

Power Sensor Manual 1

This non-square-law region may be "shaped" with meter corrections, but only for one
defined waveform, such as a CW signal. By incorporating "shaping", also referred to as
"Linearity Calibration", Boonton offers a dynamic range from 0.1 nW (-70 dBm) to 100
mW (+20 dB) with a single sensor module. For CW measurements, the entire 90 dB
range can be used, however, when dealing with non-sinusoidal and high-harmonic
content signals, the Diode Sensor should be operated only within its square-law region
(10 µW and below).

Although thermal sensors provide a true indication of RMS power for modulated (non­CW) signals, they are of limited use for characterizing the short-term or instantaneous
RF power due to their rather slow response speed. For accurate power measurements of
short pulses or digitally modulated carriers, Boonton has developed a line of wideband
diode sensors called Peak Power Sensors. These sensors are specially designed for
applications where the instantaneous power of an RF signal must be measured with
high accuracy . They are for use with the Boonton Model 4400 peak Power Meter and
the Model 4500 Digital Sampling Power Analyzer. Because the bandwidth of Peak
Power Sensors is higher than most modulated signals (30 MHz or more for some sensor
models), they accurately respond to the instantaneous power envelope of the RF signal,
and the output of the sensor may be fully linearized for any type of signal, whether CW
or modulated. Boonton Peak Power Sensors contain built-in nonvolatile memory that
stores sensor information and frequency correction factors. The linearity correction
factors are automatically generated by the instrument's built-in programmable calibrator.
With the high sensor bandwidth, and frequency and linearity correction applied
continuously by the instrument, it is possible to make many types of measurements on
an RF signal; average (CW) power, peak power , dynamic range, pulse timing, waveform
viewing, and calculation of statistical power distribution functions.

1-3 Calibration and Traceability

Boonton employs both a linearity calibration as well as a frequency response calibration.
This maximizes the performance of Diode Sensors and corrects the non-linearity on all
ranges.

Linearity calibration can be used to extend the operating range of a Diode Sensor. It can
also be used to correct non-linearity throughout a sensor's dynamic range, either
Thermocouple or Diode. A unique traceability benefit offered is the use of the 30 MHz
working standard. This is used to perform the linearization. This standard is directly
traceable to the 30 MHz piston attenuator maintained at the National Institute of
Standards T echnology (NIST). Refer to Figure 1-2. Linearity T raceability .

Power Sensor Manual 3

Power sensors have response variations (with respect to the reference frequency) at
high frequencies. Calibration factors ranging from ± 3 dB are entered into the
instrument memories at the desired frequencies. Generally, calibration factors are
within ±0.5 dB. These calibration factors must be traceable to the National Institute
of Standards Technology (NIST) to be meaningful. This is accomplished by sending
a standard power sensor (Thermocouple type) to NIST or a certified calibration house
and comparing this standard sensor against each production sensor. The predominant
error term is the uncertainty of the reference sensor, which is typically 2% to 6%,
depending on the frequency. Refer to Figure 1-3. Calibration Factor Traceability.

Power Sensor Characteristics

The power sensor has three primary functions. First the sensor converts the incident
RF or microwave power to an equivalent voltage that can be processed by the power
meter. The sensor must also present to the incident power an impedance which is
closely matched to the transmission system. Finally, the sensor must introduce the
smallest drift and noise possible so as not to disturb the measurement.

Table 2-1 lists the characteristics of the latest line of Continuous Wave (CW) sensors
offered by Boonton. The latest Peak Power sensor characteristics are outlined in Table
2-2. This data should be referenced for all new system requirements.

5107xA Series of RF Sensors

The “A” series sensors were created to improve production calibration results. These
sensors possess the same customer specifications as the non-A types (i.e.: 51075 and
51075A), however, the utilization of new calibration methods enhances the testing
performance over previous techniques. In doing this, Boonton can provide the customer
with a better product with a higher degree of confidence.

The “A” series sensors utilize “Smart Shaping” technology to characterize the linearity
transfer function. This is accomplished by performing a step calibration to determine the
sensors response to level variations. The shaping characteristics are determined during
the calibration and then the coefficients are stored in the data adapter that is supplied with
the sensor. This provides improved linearity results when used with the 4230A and 5230
line of instruments with software version 5.04 (or later).

Instruments that are equipped with step calibrators such as the 4530 already perform this
function when the Auto Cal process is performed. For these instruments an “A” type
sensor performs the same as a non-“A” type and no discernable difference is realized.

calibrator unless otherwise noted.

MODELS 4531 and 4532:

The Peak Power sensors in the lower group above may be used with these models
and calibrated with the internal 50 MHz ste

calibrator. The sensors on the upper

roup may be used if the Model 2530 1 GHz Accessory Calibrator is used for

calibration.

A five-foot lon

sensor cable is standard. Longer cables are available at a higher

cost. Effective bandwidth is reduced with longer cables.
