INTRODUCTION
This manual provides descriptions and specifications for ANRITSU
MA24XXA/B Series Power Sensors (Figure 1). It also includes care
and handling information for the power sensors.
GENERAL DESCRIPTION
The MA24XXA/B Series Power Sensors consist of MA247XA/B Series
Power Sensors, MA246XA/B/C Series Power Sensors, MA248XA Se-
ries Universal Power Sensors, MA242XA/B Series Thermal Power
Sensors, and MA244XA/B Series High Accuracy Power Sensors.
These units are broadband microwave measurement components.
All models except the MA246XA/B/C Series Power Sensors, are used
with the ML2430A Series Power Meters. The MA246XA/B/C Series
Power Sensors are used with the ML2400A Series Power Meter only.
Models in each series cover the 10 MHz to 50 GHz frequency range
and have N, K, and V type RF connectors. MA246xA/B/C Sensors
cover the 10 MHz to 18 GHz range, and MA248xA/B Sensors cover
the 10 MHz to 18 GHz range. Both the MA246xA/B/C and MA248xA
have N-type RF connectors.
The 90 dB dynamic range MA247XA/B Series Power Sensors provide
stable power readings to
