MA2400xA Thermal Sensors
Description
The Anritsu MA2400xA 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.
Features
• True-RMS detection enables accurate average power
measurements of any signal type
• 50 dB dynamic range
• Wide frequency coverage from 10 MHz to 50 GHz (sensor
dependent)
• Calibration factors stored in EEPROM
MA246xD Fast Diode Sensors (obsolete)
Description
The MA246xD fast diode sensors from Anritsu have a rise time of
0.6

s. This, together with a sensor video bandwidth of 1.25 MHz,
makes them the ideal solution for power measurements on
N-CDMA (IS-95) signals.
The MA246xD sensors can be used with the ML2407A/08A
(obsolete products), ML2430, ML2480, and ML2490 series power
meters. This combination of meter and sensor provides fast signal
processing and sampling speeds. Average power, peak power and
crest factor on N-CDMA signals can be measured and displayed.
