Information:
                                    The Model 4230A Series is a DSP (digital signal processor)
based family of single or dual channel, solid state RF power
meters. They are capable of measuring RF power levels from
-70 dBm to +44 dBm. The RF frequency range and power level
range are sensor dependent. Boonton 51000 series sensors
provide measurement capabilities for frequencies from 10 kHz
to 100 GHz.
1-5. FEATURES.
1-6. Power Sensors. A wide range of diode and thermocouple
power sensors for both coaxial and waveguide applications
are available for use with the Model 4230A. Sensor data
adapters are supplied with the Model 4230A, however, the
power sensor must be ordered separately.
1-7. Diode sensors measure the voltage across a precision
resistor, using specially selected diodes. Detection is
square law (true RMS) over approximately the lower
two-thirds of the sensor's dynamic range, and peak detecting
over the upper portion. Because the instrument is calibrated
for sine waves over the entire range, measurements at the
top one-third of the sensor's dynamic range are valid only
for non-modulated signals. In the RMS region, linearity is
excellent, and any signal type can be measured. The diode
range has been extended into the peak detecting region with
the use of real time shaping for the diode curve. When
coupled with the high sensitivity of the diode, such shaping
allows a dynamic range of 90 dB. Diode sensors are rugged
and have an overload headroom of more than 5 dB for
continuous signals. The dynamic range in the RMS region can
be extended further through use of an external attenuator.
1-8. Thermal sensors measure the voltage developed across a
dissimilar metal junction caused by the thermal gradient
generated by the RF power being measured. Because these
sensors are heat detecting, they provide true RMS response
over their entire range. Very high peak powers (15 to 30 watts)
can be accommodated for very short duty cycles and still
provide valid results. The dynamic range is 50 dB. Thermal
sensors are not as sensitive as diode sensors.
1-9. The sensor data adapter contains non-volatile memory
for storage of the calibration data. In addition,
calibration data for up to four sensors can be stored in the
instrument's nonvolatile memory. The user can enter both the
linearity and high frequency sensor calibration correction
data which are supplied with each sensor. For sensors
ordered with the Model 4230A, the calibration data is loaded
into the sensor data adapter prior to shipment. When the
frequency ofthe RF signal to be measured by one of these
sensors is entered, the instrument looks up the appropriate
calibration factors, interpolates as necessary, and
automatically applies the correction to the measured value.
Calibration factors for sensors ordered with the instrument
are stored in the plastic pouch attached to the inside of
the instrument's top cover.
1-10. Simple Instrument Setup and Operation. In the
operating mode the functions: Frequency, Averaging Time,
Reference Level, Zeroing/Calibration are selected with a
single keystroke. Values for these parameters are displayed
and can be adjusted by using the arrow and enter keys.
Additional operating parameters can be modified through the
menu driven structure accessible via the <Menu> and <Sensor>
keys.
1-11. Alphanumeric Display. The alphanumeric LCD provides
clear, unambiguous readouts of the instrument's setup and
measurement values. Simultaneous display of both channels is
available in dual channel mode. A bar graph provides a
display of the channel's measured value for nulling and
peaking applications.
1-12. Selectable Ranging. Any of seven measurement ranges,
or autoranging, can be selected during instrument setup. The
selection will be held until it is changed, or until the
instrument is turned off. When measuring signals with levels
that fall within a narrow range, selecting one specific
instrument range may reduce measurement time. Autoranging is
useful if the RF signal level is unknown, or if RF signals
with widely varying levels are to be measured.
1-13. Selectable Filtering. Measurement speed and display
stability can be optimized through the use of selectable
filtering. Filter times can be adjusted up to 20 seconds
maximum in 50 millisecond increments.
1-14. Zeroing. Automatic zeroing (nulling of offsets for the
sensor and input channel) is done independently on each
range to eliminate zero carryovers.
1-15. Built-In Precision Calibrator. A built-in 50 MHz
calibrator provides an accurate, stable, and convenient
power source for calibration of the instrument to specified
tolerances. The calibrator may be toggled on or off from the
Setup menu. The connector is normally mounted for front
panel access, however option-02 changes this to rear panel
access.
1-16. Chart Recorder Output. A 0 to 10 volt dc output,
proportional to the measurement values, is available for
application to a chart recorder.
1-17. Optional Interface. A RS-232 option enables full
service remote control of the Model 4230A. All instrument
controls and values, except power on and off, are accessible
to a bus controller in the remote operating mode.
