of this instrument. Failure to comply with these precautions or with specific warnings elsewhere in this
manual violates safety standards of design, manufacture, and intended use of the instrument. Boonton
Electronics assumes no liability for the customer’s failure to comply with these requirements.

THE INSTRUMENT MUST BE GROUNDED

To minimize shock hazard the instrument chassis and cabinet must be connected to an electrical ground.
The instrument is equipped with a NEMA three conductor, three prong power cable. The power cable must
either be plugged into an approved three-contact electrical outlet or used with a three-contact to a two­contact adapter with the (green) grounding wire firmly connected to an electrical ground in the power
outlet.

DO NOT OPERATE THE INSTRUMENT IN AN EXPLOSIVE ATMOSPHERE

Do not operate the instrument in the presence of flammable gases or fumes.

KEEP AWAY FROM LIVE CIRCUITS

Operating personnel must not remove instrument covers. Component replacement and internal adjustments
must be made by qualified maintenance personnel. Do not replace components with the power cable
connected. Under certain conditions dangerous voltages may exist even though the power cable was
removed, therefore; always disconnect power and discharge circuits before touching them.

DO NOT SERVICE OR ADJUST ALONE

Do not attempt internal service or adjustment unless another person, capable or rendering first aid and
resuscitation, is present.

DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT

Do not install substitute parts or perform any unauthorized modifications or the instrument. Return the
instrument to Boonton Electronics for repair to ensure that the safety features are maintained.

SAFETY SYMBOLS

This safety requirement symbol (located on the rear panel) has been adopted by the
International Electro-technical Commission, Document 66 (Central Office) 3, Paragraph

5.3, which directs that an instrument be so labeled if, for the correct use of the instrument,
it is necessary to refer to the instruction manual. In this case it is recommended that
reference be made to the instruction manual when connecting the instrument to the proper
power source. Verify that the correct fuse is installed for the power available.

The CAUTION symbol denotes a hazard. It calls attention to an operational procedure,
practice or instruction that, if not followed, could result in damage to or destruction of
part or all of the instrument and accessories. Do not proceed beyond a CAUTION symbol
until its conditions are fully understood and met.

The NOTE symbol is used to mark information which should be read. This information
can be very useful to the operating in dealing with the subject covered in this section.

The HINT symbol is used to identify additional comments which are outside of the
normal format of the manual, however can give the user additional information about the
subject.

1.2 Description

The 4540 Series RF Power Meter is the latest generation of BOONTON RF Peak Power Meters and
Analyzers, including Models 4400, 4500, 4400A, 4500A, 4500B and 4530. The 4540 Series, when
operated with Boonton peak and CW power sensors, provides one of the most versatile power measuring
systems available, with capability to make over 20 different power related measurements on captured
signals. The 4540 is available as the single-channel Model 4541 or the dual-channel Model 4542.

The 4540 is really several instruments in one, and can function as a CW Power Meter, a Peak Power Meter,
a Statistical Power Analyzer, and an RF Voltmeter. It accepts the full series of Boonton RF power and
voltage sensors, which includes coaxial dual-diode sensors and thermal sensors.

The 4540 Series instruments provide three basic measurement modes - pulse power, modulated power, and
statistical power. Each mode is targeted towards a specific type of measurement.

The Pulse Mode is used with peak power sensors. The instrument functions as an enhanced peak power
analyzer and provides the functionality of a random repetitive sampling oscilloscope for viewing and
analyzing the RF power envelope of signals up to 40 GHz. The RF frequency range and detection
bandwidth are sensor model dependent. Accuracy approaches that of average-only power meters, but with
the ability to capture wide bandwidth power-versus-time data. With the requirement of an internal or
external trigger event it can automatically measure up to 15 characteristics of the RF power envelope.
These are peak power, pulse power, average power, pulse width, risetime, falltime, overshoot, pulse period,
pulse repetition rate, duty cycle, top amplitude, bottom amplitude, offtime, edge delay and the delay
between two RF pulses. In addition to these automatic measurements, the 4540 offers a powerful set of
marker measurements, which includes the ability to make marker measurements at full accuracy,
independent of vertical scale or offset. This is possible because of the use of non-linear signal processing
techniques, and high-resolution analog to digital converters that provide rangeless operation. In addition,
the markers can be used to define regions of the waveform for analysis. This analysis includes average
power of a portion of the waveform, minimum power, and maximum power.

The Modulated Mode is designed for continuous, true average power measurements of complex modulated
signals. When used with Boonton Peak Power sensors, Modulated Mode is similar to the operation of a
conventional CW power meter, but does not suffer the measurement inaccuracies that occur when some
diode sensors are used to measure modulated signals. For applications that require very wide dynamic
range, Boonton CW power sensors can be used for CW signals or low-level modulated signals up to 110
GHz. A scrolling graphical trace or multi-reading text presentation is available.

The Statistical Mode of the 4540 Series is used for advanced analysis of non-periodic modulated signals.
This mode does not require a trigger event to make measurements and is useful for signals that are noise­like such as CDMA, OFDM, or QAM. In Statistical Mode, the RF signal is sampled continuously at high
speed, without discarding or losing any data. The acquired sample population is processed statistically in
real time to determine peak power, average power, minimum power, peak to average power ratio, and
dynamic range, while reporting the sampling time and total number of samples captured.

Rangeless operation ensures that a representative power sample population can be acquired and analyzed in
minimum time. By analyzing the probability of occurrence of power levels approaching the absolute peak
power, it is possible to characterize the occasional power peaks that result in amplifier compression and
data errors. Because of the random and very infrequent nature of these events, they are next to impossible
to spot with the conventional techniques used in other power meters. In addition, the instrument’s
extremely wide video bandwidth ensures that even the fastest peaks will be accurately measured.

The statistical analysis of the current sample population is displayed using a familiar, normalized CCDF
presentation. The CCDF expresses the probability of occurrence of a range of peak-to-average power ratio
on a log-log scale, and a cursor allows reading of CCDF point. As with all other graphical displays, the
trace can be easily scaled and zoomed, or the statistical data may be presented in a tabular format.

1.3 Features

Software. A 32-bit control computer running a real-time operating system provides display, I/O

and system memory functions for the instrument. The instrument also contains a dedicated
floating-point DSP, FPGA and memories to perform the measurement functions. Software updates
are easily made using the rear-panel Ethernet port.

Auto-Setup. The instrument will automatically select a vertical scale, vertical offset, timebase,

holdoff and trigger level to display at least one pulse period at full amplitude of the full waveform.

Menu-Driven Operation. Setup and control of the instrument is menu-driven to simplify

operation. User-selected parameters appear in a menu to the right of the waveform, together with

applicable variables. Selections are arranged opposite adjacent ―soft keys‖ that select parameters

and activate data entry controls. Required numerical values are entered through the keypad or
with flexible increment/decrement using the ▲▼arrow keys.

Color Display. Waveforms, control menus, measurement values and related text are displayed on a

4.0-inch diagonal, 320 x 240 pixel color LCD. The display has an adjustable brightness CCFL
backlit, and the built-in ―screen saver‖ function may be used to dim the backlight automatically to
further extend lamp life.

Dual Independent Channels. When equipped with the optional second measurement channel, the

instrument can display two pulsed RF signals simultaneously or one pulsed signal and one CW
signal. Each channel is calibrated and all channel parameters are channel-independent.

Balanced Diode Sensors. The balanced diode sensor configuration of most Boonton peak and CW

power sensors provides high sensitivity and even-order harmonic suppression. Low VSWR
minimizes mismatch errors. Frequency Calibration factors traceable to NIST standards are stored
in each power sensor’s EEPROM and downloaded to the instrument. A thermal sensor in each
peak power sensor tracks temperature variations.

Built-In Precision Calibrator. A 50 MHz step calibrator, traceable to NIST, enhances

measurement accuracy and reliability. The user-selectable automatic calibration routine calibrates
most sensors and the instrument in steps over the full dynamic range.

Adjustable Averaging. Random repetitive sampling at rates up to 5 GSa/sec followed by

waveform averaging with an exponential filter (performed on each point of the waveform) reduces
noise contribution and provides accurate, stable measurements. The number of repetitions to be
averaged can be adjusted to the smallest value that achieves the desired noise suppression, thereby
avoiding excessive averaging delays.

Automatic Waveform Analysis. The instrument can measure fifteen pulse parameters related to

power, time and/or frequency. All programmed measurements are made automatically and
displayed in text mode. Measurement information is available directly, eliminating the need for
interpretation by the user.

Single-Shot Measurements. The 50 MHz sampling rate yields a 5 MHz single-shot bandwidth (10

samples per pulse) for capturing and analyzing infrequent events in the time domain.

Flexible Remote Control. All instrument functions except power on/off can be controlled

remotely via the standard GPIB bus interface, USB port, or Ethernet LAN connection. Setup of
interface parameters is menu driven; front panel indicators keep the user informed of bus activity.
Remote control programming is performed using industry-standard SCPI programming syntax.

Stored Configurations. For applications in which the same instrument configurations are used

repeatedly, up to 25 complete setups can be stored and recalled by user-defined filename. The
instrument also provides built-in setups for many common signal types.

Hz, single-phase, AC power source. Maximum power consumption is 50W and 70VA. For metric fuse sizes, use the metric
fuse kit supplied. Connect the power cord supplied with the instrument to the power receptacle on the rear panel. See Figure
3-2.

Caution Before connecting the instrument to the power source, make certain that a 1.0-ampere time delay fuse (type

T) is installed in the fuse holder on the rear panel.

Before removing the instrument cover for any reason, position the input module power switch to off (0 =
OFF; 1 = ON) and disconnect the power cord.

2.3 Connections

Sensor(s) Connect the sensor that covers the frequency range of the measurement to the CHANNEL 1 sensor

connector on the front (Standard) or rear (Optional) panel, as follows. Connect the sensor to the sensor
cable by aligning the red mark on each part and pressing the connectors together firmly. Connect the sensor
cable to the CHANNEL 1 Input, holding the red mark on the cable connector up. For two-channel
measurements, use the same procedures to connect the second sensor to the CHANNEL 2 Input.

Note If the sensor connector is not a type N, install the appropriate adapter (from the accessories kit) on the

calibrator output connector.

Trigger Most triggered applications can use the RF signal applied to the sensors for triggering. For measurements

requiring external triggering, connect the external trigger signal to the EXT TRIGGER BNC connector on
the rear panel.

Remote If the instrument is to be operated remotely using the GPIB (IEEE-488) bus, connect the instrument to the

bus using the rear panel GPIB connector and appropriate cable. For USB control, the rear panel USB
connector should be used, and for Ethernet control, connect to the rear panel LAN connector. In most
cases, it will be necessary to configure the interface using via the System > I/O Config menus.

2.4 Preliminary Check

The following preliminary check verifies that the instrument is operational and has the correct software installed. It should
be performed before the instrument is placed into service. To perform the preliminary check, proceed as follows:

1. Press the lower half (marked "0") of the power switch in the center of the power module on the rear panel.

2. Connect the AC (mains) power cord to a suitable AC power source; 90 to 260 volts AC, 47 to 63 Hz, with a capacity in

excess of 75 W. The power supply will automatically adjust to voltages within this range.

3. Press the upper half (marked "1") of the power switch in the center of the power module on the rear panel. If the

instrument was last in the standby state, it will enter standby mode. If it was last ―on‖ when power was removed, it will
return to the ON state.

4. If the 4540 is in standby mode (no display or power indication present), press the green ON/STBY key (marked with the

international 0/1 on/standby symbol) on the front panel to turn the instrument on. The display backlight should turn on
and there will be several clicks as the instrument boots.

5. After a self-check, the instrument will execute the application program. A bootup splash screen should briefly appear

that shows the instrument name, model number, and software version, and indicates boot status. After several moments
a screen similar to Figure 2-2 should be displayed.

6. On the front panel, press the Menu key followed by the More softkey, then on the softkeys, press System > Reports >

Configuration REPORT. A display similar to Figure 2-3 should appear.

7. Verify that the instrument serial number and model number shown are correct, and the correct number of channels

(single or dual) appears. If the channels are configured for non-standard length input cables, the expected sensor cable
length expected may also be appended. If any of this information appears incorrect, contact Boonton Electronics for
technical support.

8. Follow steps in Sections 3.4 and 3.5 to initialize and calibrate the instrument.

Note If the display does not appear or differs significantly from the illustrated display, try reinstalling the

instrument software as described in Section 7.5 "Software Upgrade". If this does not correct the problem,
contact Boonton Electronics for technical support.

Note You will not be able to perform measurements with the 4540 Series until an AutoCal procedure (see

Section 3.5) has been performed on the measurement channel. However, AutoCal data is saved when
power is removed, so AutoCal need not be repeated with each power-on.

3. Getting Started

This chapter will introduce the user to the 4540 Series. The chapter will identify objects on the front and rear panels, identify
display organization, list the initial configuration of the instrument after reset, demonstrate how to calibrate the sensors, and
provide practice exercises for front panel operation. For additional information you should see Chapter 4 "Operation."

3.1 Organization

Subsection 3.2 Operating Controls, Indicators and Connections identifies the control features and connections on the
front and rear panels.

Subsection 3.3 Monitor Display describes the data fields in the standard (graphic mode) display.

Subsection 3.4 Initialization explains how to turn the instrument on for the first time, connect a sensor, set the instrument up

for operation, and initialize it to a known state. See Table 3-3. for initialized parameters and their values.

Subsection 3.5 Calibration is critical to the proper operation of an instrument. The 4540 Series comes with a 50 MHz
programmable reference calibrator. Before making any measurement the sensor(s) may have to be calibrated with this
source.

Subsection 3.6 Making Measurements describes the different measurements modes of the 4540 Series.

3.2 Operating Controls, Indicators and Connections

Figures 3-1 and 3-2 illustrate the controls, indicators and connectors on the front and rear panels, respectively, of the
standard instrument. Refer to Table 3-1 for a description of each of the illustrated items. Connectors indicated by an asterisk
(*) may be front or rear-mounted, depending on the option selected. The function and operation of all controls, indicators
and connectors are the same on the standard and optional models.

1 1 Internal Calibrator The output of the built-in 50MHz programmable calibrator is available from a

Type-N connector located on the front, or optionally on the rear panel of the
instrument. This calibrator is used to automatically calibrate sensor offset and
linearity, and can also be used as a general purpose calibration signal source.

2 2 Sensor Inputs One or two sensor inputs are located on the front, or optionally on the rear panel

of the instrument. These are 10-pin precision connectors designed to accept only
Boonton Peak or CW power sensors and Boonton voltage probes.
