1. GENERAL INFORMA TION

1.1 DESCRIPTION

The 4530 Series RF Power Meter is a new generation of instruments. It allows high-resolution power measurement of a wide range of CW and modulated RF signals over a dynamic range of up to 90dB depending on sensor. The power meter is available configured as the single-channel Model 4531, or as the dual-channel Model 4532. For the remainder of this manual, the series designation of 4530 will be used to indicate either model, except when otherwise stated.
The 4530 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. Sensor data and calibration information is automatically downloaded from the sensor or “smart adapter” whenever a new sensor is connected, eliminating the need to manually enter calibration factors.
When used as a CW power meter, the 4530 provides seamless measurement performance due to the extremely wide dynamic range of its input stage. Thermal and peak power sensors require no range switching under any conditions, and even CW diode sensors spanning a 90dB dynamic range require only two widely overlapping ranges. This means that practically any measurement can be performed without the interruptions and non-linearities associated with the range changes of conventional power meters.
For modulated signals, the 4530 can make accurate average and peak power measurements with modulation band­widths as high as 20MHz, making it ideal for high-speed digitally modulated carriers such as CDMA, W-CDMA, GSM, TDMA, HDTV and UMT . Periodic and pulse waveforms can be displayed in graphical format, and a host of automatic measurements are available which characterize the time and power profiles of the pulse. Effective sampling rates up to 50MSa/sec and user programmable cursors allow instantaneous power measurements at precise time delays from the pulse edge or an external trigger as well as time gated or power gated peak and average power.
For spread-spectrum or randomly modulated signals such as CDMA, the 4530’s powerful statistical analysis mode allows full profiling of the power probability at all signal levels. Sustained acquisition rates in excess of one million readings per second along with rangeless operation insure that a representative 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 universal power meters. In addition, the instrument’s extremely wide video bandwidth insures that even the fastest peaks will be accurately measured.
The 4530’s powerful dual-processor architecture permits advanced measurement capabilities with unprecedented speed and performance. A high-speed, floating-point digital signal processor (DSP) performs the measurements. It gathers and processes the power samples from the sensors, performs time-stamping, linearity correction, gain adjust­ment and filtering, all in fractions of a microsecond. The processed measurements are then passed to a dedicated, 32-bit I/O processor that monitors the keyboard, updates the LCD display and responds to RS-232 and GPIB requests for formatted measurements. This design eliminates the speed tradeoffs between measurement data input (acquisition) and output (over the GPIB) that are so common among other power meters.
, the 4530 provides seamless measurement performance due to the extremely wide
Instrument operating firmware is stored in flash memory that may be field reprogrammed with any PC via the onboard RS-232 port. Free firmware upgrades permit the easy addition of new features or capabilities that may become available in the future.

Table 3-1 references each operating key or connector to a callout in Figure 3-1or 3-2 and briefly describes the key function
Table 3-1. Keyboard Controls and Connectors
Item Figure 3-1 Function
50 MHz Calibrator 1 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.
Display 2 The 4530 Series RF Power Meter uses a 160x80 pixel graphic liquid crystal
display module with a switchable LED backlight. The display contrast may be adjusted by holding down the ESC key while pressing the keys.

< and > Keys 3 Used to navigate between levels of the menu structure while in Menu
Mode or Zero/Cal Mode and to select individual editing numeric param­eters. In Text Mode and Graph mode these keys can be used to switch the display between channels. In T ext or Graph Edit Modes, the < and > keys scroll the header line left or right through a list of editable param­eters.
∧∧
∨∨
and ∨ Keys 4 Used to scroll up and down through a list of items when in Menu Mode
or Zero/Cal Mode. They are also used to increment and decrement pa­rameter values or individual digits when editing. In certain Text Modes, these keys can be used to page up or down through a series of measure­ment screens.
∧∧
(Key Repeat) -- - Note - If the ∧ or ∨ key is pressed and held when incrementing or
decrementing a variable, it enters auto-repeat mode. At first, there is a short delay, and then the number begins to increment at a slow rate. The increment rate accelerates to a medium rate after 2 seconds, and to a high rate after 7 seconds. To select and hold the medium repeat rate, double­click the key - releasing and immediately pressing the key will inhibit the high-speed auto-repeat rate so the value doesn’t “run away” just as the desired number is being approached.
Enter/Run Key 5 Activates a menu selection or completes update of a parameter in Menu
Mode or Zero/Cal Mode. Pressing Enter/Run while stopped in Text Mode or Graph Mode will start (or restart) the measurement process.

in a numeric format. Pressing Text while already in T ext Mode toggles the top portion of the display between the normal T ext Mode header and Edit Mode for each active channel.
Graph K ey 1 0 Places the instrument in Graph Mode to display the current measurement
waveforms in a graphical format. Pressing Graph while already in Graph Mode toggles the top portion (header) of the display between the normal Graph Mode header and Edit Mode for the active channel.
Menu Key 11 Places the instrument in Menu Mode to allow navigation of the menu
structure. Pressing Menu while already in Menu Mode returns the user to the top-level Main Menu.
Sensor 1 - 2 12 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 sensors. The sensor inputs are not measurement terminals and cannot be used for other than the intended purpose.
CAUTION
Do not attempt to connect anything other than a
Boonton sensor or sensor adapter to the Sensor inputs!
GPIB 13 A rear-panel 24-pin GPIB (IEEE-488) connector is available for connect-
ing the power meter to the remote control General Purpose Instrument Bus. GPIB parameters can be configured through the menu.

EXT CAL CONTROL 14 An RJ-11 type modular telephone jack is used to connect the instrument
to a Boonton Model 2530 1GHz Programmable Calibrator. This feature must be used to calibrate peak power sensors that cannot be calibrated at 50MHz, the operating frequency of the built-in calibrator.
CAUTION
Do not attempt to connect the External Calibrator
Control RJ-11 port to a telephone line or to any device
other than a Boonton Model 2530, 1 GHz Calibrator!
RECORDER OUT 15 A rear-panel BNC programmable analog output is available for connec-
tion to an external chart recorder or other device. The output voltage range is unipolar or bipolar 10 volts, and a 9K output impedance allows for simple scaling using a single external load resistor. The output can be programmed to produce a voltage proportional to signal level, or a logic­level status voltage for signaling when the RF power is above or below preset “alarm limit” thresholds. Recorder output parameters can be con­figured through the menu.
VIDEO OUT 1-2 1 6 Two rear-panel video BNC outputs are used to view the demodulated RF
envelope for each channel on an external oscilloscope when using peak sensors. The output voltage is 0 to 2.5 volts, and is approximately pro­portional to the logarithm of the sensor power. These outputs are uncalibrated, and should not be used for making any type of external measurement.
EXT TRIGGER 17 A rear-panel BNC input is available for connecting an external trigger
source to the power meter. The input impedance is 1 megohm to allow triggering from a common 10x oscilloscope probe, and the input voltage range is +5 to -5 volts to simplify triggering from logic-level signals.
RS-232 18 A rear-panel 9-pin female “D” connector is used to connect the instru-
ment to a PC or other serial device. The power meter will directly interface with most PC serial ports RS-232 parameters can be configured through the menu.
AC Line Input 19 A multi-function power input module (lower right of rear panel) is used to
house the AC line input, main power switch, and safety fuse. The module accepts a standard AC line cord, included with the power meter. The power switch is used to shut off main instrument power . The safety fuse may also be accessed once the line cord is removed. The instrument’s power supply accepts 90 to 260VAC, so no line voltage selection switch is necessary.

3.3 DISPLAY FUNCTIONS

The screen display of the 4530 is divided into three sections: the header, the measurement window and the status window. Because these functions apply to all modes of operation, it is very important to understand them thoroughly.
∧∧
∨∨
Note that the display contrast may be adjusted by holding down the ESC key while pressing the
Header Status Window
or ∨ keys.
Measurement Window
Figure 3-3. Display Functions
3.3.1
Header. The header appears at the top of the screen. It displays a title line and a line of text describing the
status of the currently highlighted item (sensor status, measurement status or auxiliary measurement values). If the item is a submenu, a short description of the menu’s function will appear . If it is a parameter , the present value for that parameter is shown. If it is an action item, the action will be described, and upon activation, the message will change to indicate that the action has occurred. The header is also used as a two-line parameter editing window when in the Edit mode.
3.3.2 Measurement Window. The major portion of the screen displays the current measurement results in a single
(4531) or split-channel (4532) format. The text display shows a trace for the primary measurement of the channel(s) (usually average power), which updates as samples are acquired. In addition, while in the text mode, the channel source (sensor, reference, or math function) is displayed along with measurement units. While in the Graph mode, at slower display timebases, the trace will roll from right to left in chart recorder format, while faster timebases use an oscilloscope-like sweep.
3.3.3 Status Window. The right-hand portion of the screen displays six annunciators that indicate status for the
GPIB, calibrator and measurement. The first four indicate GPIB status: REM, TLK, LSN, and SRQ. Position five is a measurement status indicator, that can display: STOP, RUN, AUTO, ARMD, or SNGL. Position six displays CAL when the calibrator output is active.
3.3.4 Channel Selection. Pressing the < or > keys while in text or graph mode toggles the measurement window
between channels. If Channel 1 is active, pressing < from a split-channel display will display only Channel 1, and pressing > at that point returns to the split channel display. Similarly, pressing > from the split-channel screen switches to the Channel 2 only display and < returns to the split-channel format. Note that in the single­channel Model 4531, there is no “Channel 2 only” display , and while the split-channel display is present, there are no measurements for Channel 2.
3.3.5 Header / Page Selection. Pressing the
a series of three “measurement pages”, each displaying a different set of measurements or status indicators. In single-channel text mode, the entire measurement window may change, while in graph mode or split-channel format, only the “auxiliary” measurements shown in the header will change.

3.4 OPERATING MODE SUMMARY

The 4530 can operate in several modes. It is possible to move between these modes without interrupting the measure­ments currently being performed, even though the measurement display may not always be present.
3.4.1 Menu Mode. The Menu Mode and is used to set operating parameters and start or stop measurements. A
series of displayed menus may be navigated using the front-panel arrow keys to access any instrument function. The menu is an inverted tree, which begins at the top-level Main Menu, and branches downwards through several levels of menu items and submenus. Refer to Table 3-5 for a summary of the instrument’s entire menu structure. The first time the Menu key is pressed after power-up, the instrument enters the Menu Mode and displays the Main Menu. Subsequent entries into Menu Mode will return the user to the same position in the menu tree that was last used. Pressing the Menu key twice (or pressing it at any time when already in Menu Mode) will always return to the Main Menu.
Figure 3-4. Menu Mode
3.4.2 Text Mode. In T ext Mode, the measurements are presented in a numerical format. A summary split-channel
(4532) display which shows the key measurement values for each channel in a large font may be selected, or detailed single-channel (4531) display that presents a number of different measurements in a tabular format. In the dual-channel text display, a programmable bargraph can be displayed to aid in viewing fluctuating signals.
Dual Channel (Example) Single Channel (Example)

Boonton Electronics Chapter 3 4530 Series RF Power Meter Operation
3.4.3 Graph Mode. The Graph Mode can present an oscilloscope style trace of power versus time or power
versus percent probability in statistical mode. Each channel may be viewed individually, or both can be overlaid to make channel-to-channel comparisons. User programmable cursors can be moved back and forth or up and down on the trace to define measurement regions of interest.
Figure 3-6. Graph Mode (Example)
3.4.4
Edit Mode. Edit Mode is an extension of the basic Graph Mode or Text Mode operation. The screen’s
measurement window continues to display and update the active measurement, but the two-line header area at the top of the screen is used as an edit window. The arrow keys scroll through a list of commonly accessed parameters, and allow these parameters to be updated “on the fly” without the need to return to Menu Mode.
