MODULATED POWER
MEASUREMENTS
The Giga-tronics 80400A Series
Modulated Power Sensors let you
measure the average power of ampli-
tude modulated, burst modulated and
other complex modulated signals — such
as TDMA signals — at bandwidths up to
40 kHz.
The Giga-tronics 80600A Series Modulated
Power Sensors provide bandwidth up to
1.5 MHz to measure the peak and average
power of CDMA signals.

Sensor Measurement Capabilities
And the Giga-tronics 80701A Modulated
Power Sensor operating with the 8650A
power meter, provides system bandwidth
up to 10 MHz to measure the peak and
average power of wide band, third-genera-
tion CDMA signals over an 80 dB range.
