Complements Your Existing Instrument

The Anritsu MA24105A Inline Peak Power Sensor is designed to take accurate average power measurements over 2 mW to 150 W, from 350 MHz to 4 GHz. The sensor employs a "dual path" architecture that enables True-RMS measurements over the entire frequency and dynamic range allowing users to measure CW, multi-tone and digitally modulated signals such as GSM/EDGE, CDMA/EV-DO,W-CDMA/HSPA+, WiMAX™, and TD-SCDMA.

The forward direction path also include a 4 MHz bandwidth channel that has peak and comparator/integrator circuits that add measurement functions such as peak envelope power (PEP), crest factor, complimentary cumulative distribultion function (CCDF), and burst average power. Another detection circuit on the reverse direction adds reverse power measurement capabilities including reverse power, reflection coefficient, return-loss, and SWR. The presence of a micro-controller along with signal conditioning circuitry, ADC, and power supply in the sensor makes it a complete miniature power meter

High Accuracy Measurements

Accurate power measurements in the field are important for verifying that transmitter outputs are operating at specified levels. For example, service technicians need to verify base station output power because lower output power can quickly translate into large coverage differences. Highly accurate average power measurements to 150 W are assured as the calibration data is stored directly in the sensor and all necessary corrections (frequency and temperature) are done inside the microprocessor of the sensor. Also, the return loss and directivity of the instrument are optimized to maintain high accuracy. The standards used to calibrate this sensor are directly traceable to NIST.

Continuous Monitoring of Radio Systems

This sensor is designed to have good match and low insertion loss making it ideal for continuous monitoring of transmitter power and antenna reflections. The data logging function in the PowerXpert™ software application for PC equips the user the ability to record measured power over time to a hard disc or other storage media. This is useful for long term drift measurements, environmental testing, and trend analysis. A user settable data logging interval allows a frequency of measurement adjustment to match the user test application requirements. Data are stored as comma-separated values (.csv) that can be directly opened in Microsoft™ Excel allowing powerful custom analysis of measured data.

Ideal for Field

The MA24105A power sensor provides lab performance accuracy in a rugged and portable field solution. The sensor is accurate over a wide temperature range (0 °C to 55 °C), making it perfect for cellular base station installation and maintenance applications. Field and service technicians will appreciate the small size and versatility of this stand-alone unit as they will not have to carry extra elements, heavy high power attentuators, or power meters. A very easy to use PC application with a large display makes the job even easier for technicians who need accurate measurement results quickly.

Average Measurements of CW, Pulsed, or Modulated Signals

Maximum power handling capacity of the sensor terminated with a load having VSWR of 1.5 and 3.0.

ma24105a_max_power

The MA24105A is rated to meet all specifications up to an average input power level of 150 W, depending on load match. Time varying and bursted signals can have a peak power up to 300 W. To ensure accurate readings, the peak to average ratio (crest factor) of signals must be less than 12 dB.

Peak Power, Crest Factor, Burst Average and Complementary Cumulative Distribution Function (CCDF)

The MA24105A and associated PowerXpert™ application provide information critical to development, manufacturing and operation of modern communications systems. The Peak Power function enables the user to determine the maximum power of the modulated signal envelope for signals with a modulation bandwidth of < 4 MHz. The ratio between the Peak Power and Average Power result provides the Crest Factor. Of particular use in TDMA systems, the Burst Average Function uses duty cycle information obtained either automatically or as user-entry to calculate the average power during a burst based on the measurement of Average Power. Critical to those working with spread spectrum systems, which exhibit a non-deterministic envelope, the CCDF feature shows the percentage of the time that the peak power exceeds a user-set threshold.

Reverse Power, Reflection Coefficient (magnitude), Return Loss and Standing Wave Ratio (SWR)

The MA24105A sensor´s capability to measure both forward and reverse average power also permits the user to gain information about the load mismatch. This result is conveniently available in Reflection Coefficient (magnitude), Return Loss and SWR forms.

Optimized for Production

The MA24105A facilitates lab quality measurements on the production floor for a fraction of cost of existing solutions. Since the sensor is connected directly to the PC, there is no need for a base unit saving valuable rack space. The Inline Sensor can measure signals with levels as low as 2 mW, thus eliminating the need of terminated power sensors in the production line resulting in reduced capital expenditure and set up costs. The sensor´s speed is optimized for best accuracy and noise performance thus making it suitable for wide variety of ATE applications. Multiple sensors can be connected and remote controlled via a single PC allowing flexibility to match specific measurement needs. A software toolkit is supplied with every sensor containing a sample program with source code for controlling the sensor. The 1 mW reference calibrator typically needed by power meters has also been eliminated as the connecting USB cable only transfers digital data (corrected power), minimizing test station complexity, sensor handling and test times.

Remote Monitoring via LAN or Data-Logging

ma24105a_remote_monitoring

Since the USB cable connected to the sensor only transfers corrected power back to the host, a 1 mW reference calibrator is not required. USB data transfer capabilities limit the cable length to 5 meters prohibiting remote monitoring.

However, this limitation can be overcome by installing a low cost USB-to-LAN hub converter (e.g. BELKIN™ F5L009) at the measurement site along with the MA24105A. In this way, power monitoring can be performed across continents if desired. Or, data can be logged in a .csv file for offline analysis.

PSN50 CalXpert™

PSN50 CalXpert™ is a calibration wizard that guides you through the range connection test and performs the necessary operations to upload calibration data into the power sensor. It provides a convenient way to:

  • Perform range connection characterization
  • Upload the new range connection characterization data into the sensor
  • Upload 50 MHz sensitivity calibration and calibration factor data into the sensor*
  • Provide a report of new and old calibration data

As a precaution, PSN50 CalXpert™ will also retain a file of the old calibration data that the user can restore to the sensor using PSN50 CalXpert™ if required.

*PSN50 CalXpert™ does not control the full suite of equipment to obtain sensitivity calibration and calibration factor data - it is assumed that users have access to an appropriately equipped calibration lab to obtain this data. PSN50 CalXpert™ can be used with a PC to read the responses of the power sensor during the gathering of calibration factor and sensitivity data

MA24002A / MA24004A / MA24005A


Anritsu MA2400xA Thermal Sensors
Anritsu MA2400xA Thermal Sensors

The Anritsu MA24000A series thermal sensors provide excellent power measurement accuracy over 50 dB of dynamic range. Thermal sensors use Seebeck elements, where the combined effect of a thermal gradient and charge migration between dissimilar metals gives a true reading of the average power of any incident waveform. Anritsu thermal sensors have class leading SWR and a built-in EEPROM with calibration factor and linearity correction data. This results in assured accuracy when measuring any signal.

Sensor EEPROM

The family of Anritsu power sensors store calibration data and model information within internal EEPROMS. User calibration factor tables allow frequency points or compensation for test system loss, including that from couplers and attenuators.

High Power Applications

Traditional high-power sensors are expensive and have degraded accuracy specifications. Having additional specialized sensors lead to more annual calibrations requiring more down time and expense. Using user calibration factor tables coupled with a precision high power attenuator avoids these problems and eliminates the need for specialized, high-power. Users can easily reduce operating costs and save time:

  • Compensation can be made for any precision attenuator or coupler by entering frequency and attenuation values into the user calibration factor table in the internal EEPROM.
  • The attenuation device can be semi-permanently attached. The power meter automatically applies compensation during the 0.0 dBm, 50 MHz calibration reference process.
  • User calibration factor tables are easily deactivated - allowing the power sensor to be used as a stand-alone device.
  • Up to six tables can be stored.

MA2480D / MA2481D / MA2482D


Anritsu MA248xD Series Universal Power Sensors (Average)
Anritsu MA248xD Series Universal Power Sensors (Average)

The MA2480A series are true RMS sensors with a dynamic range of 80 dB. These power sensors are modulation independent and can be used for average power measurements on a wide variety of signals, including multi-tone or W-CDMA signals. The sensor architecture consists of three pairs of diodes, each one configured to work in its square law region over the dynamic range of the sensor. Option 1 provides TDMA measurement capability, calibrating one of the diode pairs for linearity over a wide dynamic range.

Sensor EEPROM

The family of Anritsu power sensors store calibration data and model information within internal EEPROMS. User calibration factor tables allow frequency points or compensation for test system loss, including that from couplers and attenuators.

High Power Applications

Traditional high-power sensors are expensive and have degraded accuracy specifications. Having additional specialized sensors lead to more annual calibrations requiring more down time and expense. Using user calibration factor tables coupled with a precision high power attenuator avoids these problems and eliminates the need for specialized, high-power. Users can easily reduce operating costs and save time:

  • Compensation can be made for any precision attenuator or coupler by entering frequency and attenuation values into the user calibration factor table in the internal EEPROM.
  • The attenuation device can be semi-permanently attached. The power meter automatically applies compensation during the 0.0 dBm, 50 MHz calibration reference process.
  • User calibration factor tables are easily deactivated - allowing the power sensor to be used as a stand-alone device.
  • Up to six tables can be stored.

MA2490A / MA2491A


Anritsu MA249xA Series Wideband Power Sensors (Peak and Average)
Anritsu MA249xA Series Wideband Power Sensors (Peak and Average)

The MA2490A and MA2491A have been designed as dual-purpose, wideband and CW sensors. An FET switch is used to chop the signal from the sensor, to improve stability at low power levels, in CW mode. These sensors have 20 MHz video bandwidth (and 18 ns rise-time in the pulse modulated mode), and can be used to make average and peak power factor measurements on signals with rapid amplitude change, such as those in 3G/4G, WLAN, WiMAX™ and radar systems.

The family of Anritsu power sensors store calibration data and model information within internal EEPROMS. User calibration factor tables allow frequency points or compensation for test system loss, including that from couplers and attenuators.
