Introducing the P-Series Power Meters
and P-Series Wideband Power Sensors
The Agilent P-Series power meters and sensors
provide fast, accurate and repeatable power measurements for R&D and manufacturing engineers
in aerospace and defense, wireless communications and wireless 802.11a/b/g networking.
The two P-Series power meter models offer
excellent performance optimized for radar,
pulsed component test and multi-carrier power
amplifier testing:
• N1911A single channel power meter
• N1912A dual channel power meter
The P-Series power meters and sensors provide
comprehensive power, time and statistical measurements, such as peak, average, peak-to-average
ratio, maximum and minimum power measurements, time-gated and free-run power measurements, rise time and fall time measurements, as
well as the complementary cumulative distribution
function (CCDF).
High performance, wideband power sensors
The P-Series wideband power sensors only operate
with the P-Series power meters, and cover two frequency ranges:
• N1921A wideband power sensor,
50 MHz to 18 GHz
• N1922A wideband power sensor,
50 MHz to 40 GHz
Along with storing the calibration factors, linearity
and temperature compensation data in EEPROM,
the P-Series sensors are the first to provide internal zero and calibration. This feature is implemented by integrating a DC reference source and switching circuits into the power sensor. This enables
users to zero and/or calibrate the sensor while
being connected to the device-under-test (DUT).
Since zeroing and calibration are performed without the need to remove the sensor from the DUT,
this feature eliminates the multiple connections
associated with using the 0 dBm, 50 MHz
calibrator. This minimizes connector wear, reduces
test-time and measurement uncertainty.
Capture repetitive and single shot pulses
The P-Series power meters and sensors offer a
maximum sampling rate of 100 Msamples per second and a video bandwidth of 30 MHz to enable
users to capture repetitive as well as single shot
events over a wide bandwidth. Plus, perform
repeatable and accurate peak power measurements. This continuous sampling capability provides users with confidence that multiple measurements of peak power and rise time of a DUT will
give consistent results, under the same conditions.
Compatibility with more than 30 Agilent sensors
Backwards compatibility with all Agilent 8480 and
E-Series power sensors gives users additional
choices for conventional average power measurements, over a wide dynamic range and frequency
coverage from 9 kHz to 110 GHz.
