Anritsu Power Meters and Power Sensors: Accurate, Fast, and Affordable.

Power Meter Specifications ML2430A, ML2480B, ML2490A

The specifications in the following pages describe the warranted performance of the instruments for 25 ± 10 °C.
"Typical" specifications describe expected, but not warranted, performance based on sample testing. They do not guarantee the performance of any individual product. "Typical" specifications do not
account for measurement uncertainty.

Introduction

Anritsu offers the world’s most comprehensive range of power meters. The ML2490A series has the performance required for
narrow, fast rising-edge pulse power measurements (for example, radar), while the ML2480B series is suited for wideband
power measurements on signals such as W-CDMA, WiMAX, LTE, and WLAN. The ML2430A series of power meters are designed
for CW applications, offering a combination of accuracy, speed and flexibility in a low cost package.

Also available are seven different families of power sensors with frequency coverage up to 50 GHz and dynamic range up to
90 dB. Most Anritsu power sensors can work in either pulsed/modulated or CW mode (the ML2480B/90A series meters offer
both modes). In choosing a power sensor, several factors must be considered, including: frequency range, dynamic range, and
the modulation type. The rise time of the sensor should also be chosen to match the rise time of the modulation.

PowerMax™

PowerMax™ is a free graphical user-interface software for the ML2480B and ML2490A Power Meter Series.

PowerMax provides an enhanced visualization of instrument display and simplified remote control of the instrument, allowing:

• Continuous view of measurement traces in real-time

• Multiple gates and markers readings displayed at a glance

• Archiving or printing of data and plots for future analysis

PowerMax Requirements:

Hardware

• PC Processor: 1.5 GHz

• Ethernet Interface: 10/100BaseT LAN

• Memory: 1 GB RAM or greater

• Monitor: 1024 x 768 or greater resolution

Software

• Operating System: Windows XP, Service Pack 2 or higher

• Browser: Microsoft Internet Explorer 5.1 or higher

PowerSuite

PowerSuite is free software available for the ML2430A series power meters. This software is used to continuously view
measurement traces on the PC in real-time or to archive data and plots for future analysis. PowerSuite runs on a standard PC
running Windows® 95 or higher, via GPIB or RS232.

Measurement Accuracy

Power measurement accuracy can be split into several parts. The table below shows how the measurement uncertainty is composed for several
power sensors. The source is presumed to be a 16 GHz, 12.0 dBm signal with a source SWR of 1.5:1.

The uncertainties can be calculated as an RSS term as each parameter is independent. Alternatively they can be added together for a worst-case
analysis.

The Instrumentation accuracy of 0.5 % is a very small component of the overall uncertainty budget and describes the linear voltage
measurement accuracy of the power meter.

Sensor linearity describes the relative response over the dynamic range of the sensor, and is included when the sensor is measuring power
levels relative to the 0 dBm calibrator reference level. Temperature linearity is included when operating the sensor at other than room
temperature.

Noise, Zero Set and Drift are all measured on the lowest power range of the power sensor. Different types of power sensors have different
noise characteristics. Noise can be reduced by averaging.

Mismatch uncertainty is typically the largest component of the uncertainty budget – caused by the different impedances of the device under
test and the sensor. To help resolve this issue, the sensor has been designed to have a good return loss over a wide frequency range, typically
achieving significantly better results than the specification. In many cases the major contributing factor is the match of the source under test.

MA2440D MA2491A MA2470D

Mismatch is easily calculated in either dB or percentage terms from the source’s and sensor’s respective reflection coefficients.

The source match of the device under test can be improved by the use of precision attenuators with good return loss or by the use of external
levelling with a high directivity coupler or splitter.

Connector damage has significant accuracy and repeat- ability effects, and is also the most common cause of sensor damage – although it is
frequently undetected. Every MA2400A/D Series includes a hex nut connection for application of a calibrated torque wrench. Torque wrenches
assure compliance with the quality requirement and result in more consistent measurements.

Sensor calibration factor uncertainty identifies the accuracy of the sensor’s calibration relative to a recognized standard for absolute power
level. Sensor calibration factor uncertainty is included in accuracy calculations for any absolute power measurement (in dBm or Watts) and for
relative power measurements if the signals are different frequencies.

ML2400A Series is NIST traceable for more accurate, dependable measurements.

Reference power uncertainty specifies the maximum possible output drift of the power meter’s 50 MHz, 0.0 dBm power reference between
calibration intervals. Reference power uncertainty and reference to sensor mismatch uncertainty do not generally impact relative power
measurements. See the Anritsu website (www.anritsu.com) for more information and tool to calculate measurement uncertainties.
