Designed for accuracy
The Agilent E-series E9300 power sensors employ a
patented, diode-attenuator-diode topology that
ensures the accuracy and repeatability of measure-
ments across the sensors’ full -60 to +20 dBm
dynamic range. This technique has the advantage
of always using diodes in their square-law region,
where the output current and voltages respond
accurately to different modulation formats.
High-power measurement of signals with large
crest factors
With a high maximum power specification of
+25 dBm and peak power of +33 dBm (<10 micro-
seconds duration), the E9300 sensors can handle
the large crest factors typical of the newest signal
modulation formats, such as orthogonal-frequency-
division multiplexing (OFDM) and wideband CDMA,
whilst maximizing the dynamic range.
Each E9300 sensor has two measurements paths,
one for high power between -10 and +20 dBm and
one for lower power between -60 and -10 dBm. The
sensor switches between power ranges quickly and
automatically, thus providing the benefit of two
power sensors in one.
