INTRODUCTION
This manual provides descriptions and specifications for Anritsu MA24XX Se-
ries Power Sensors (Figure 1). It also includes care and handling information for
the power sensors.
GENERAL DESCRIPTION
The MA24XX Series Power Sensors consist of MA247X Series Power Sensors,
MA246X Series Power Sensors, MA248X Series Universal Power Sensors,
MA242X Series Thermal Power Sensors, MA244X Series High Accuracy
Power Sensors, MA249XX Wide Bandwidth Power Sensors, and MA241X
Pulse Power Sensors.
All models, except the MA246X, MA249X, and MA241X Series Power Sen-
sors, can be used with the ML243X, ML248X, and ML249X Series Power Me-
ters. MA246X Series Power Sensors are used with the ML2400A Series Power
Meter only.
NOTE
Anritsu ML2430A and ML2400A Power Meters must have meter firm-
ware revision 3.10 or higher to be used with Anritsu MA24xxD Series
power sensors.
The MA249X and MA241X Series Power Sensors are used with the ML248X or
ML249X Series Power Meters. The MA241X Series Power Sensors require the
power meter be equipped with 1 GHz Calibrator (Option 15). For 50 MHz BW
pulse measurements, use the MA2411B power sensor with the ML249X power
meter.
Models in the MA247X, MA242X, and MA244X series cover the 10 MHz to
50 GHz frequency range and have N, K, and V type RF connectors. MA246X
Sensors cover the 10 MHz to 18 GHz range, and MA248X Sensors cover the 10
MHz to 18 GHz range. MA249X series Sensors cover the 50 MHz to 18 GHz
range. MA241X series Sensors cover the 300 MHz to 40 GHz range. MA246X,
MA248X, and MA249X Sensors have N-type RF connectors. MA241X Sensors
have K-type RF connectors.
The 90 dB dynamic range MA247X Series Power Sensors provide stable power
readings to –70 dBm. The 87 dB dynamic range MA244X Series High Accuracy
Power Sensors contain an additional matching circuit to improve return loss per-
formance.
MA242X Series Thermal Power Sensors provide measuring speeds to 4 ms rise
and fall times in addition to exceptional return loss performance.

MA246X/C power sensors have fast 1 ms rise and fall times needed for CDMA
measurements.
MA248X Universal sensors measure average power of modulated signals such
as WDMA, multi-tone, etc.
MA249X Wide Bandwidth Sensors have a 20 MHz bandwidth needed for accu-
rate multicarrier WCDMA measurements.
MA241X Pulse Sensors havea7nsrise time when used with the ML249X Se-
ries Power Meter, useful for narrow pulse width measurements.
All MA24XX Series Power Sensors contain internal EEPROMs for storage of
calibration data as a function of frequency, power, and temperature. This allows
the power meter to interpolate and correct readings automatically.
