N9340B is now equipped with powerful features to address the field application of handheld spectrum analyzers.
Spectrum emission mask
The new N9340B adds Spectrum Emission Mask (SEM) as a standard feature.
SEM is a mask for out-of-channel emissions measurement. The SEM is defined
relatively to in-channel power. The user can set the parameters of the main
channel, out-of-channel frequency bands, and the limit lines. Included is Pass/Fail
testing for the overall spectrum emission mask and each individual out-of-channel
frequency range. The N9340B will trigger the failure indicator once any measurement
result violates the mask. Also displayed are the main channel power and the
power level vectors relative to in-channel power for each out-of-channel frequency
range. The user can save the spectrum scan, the mask, the data or screenshot
for later analysis and reporting.
Spectrogram
Now you can take advantage of the spectrogram display to view the behavior
of varying signal parameters over time. The N9340B includes spectrogram as
a standard feature. The scrolling three-dimensional display is noted for its
ability to track the frequency and power behavior over the time, particularly
intermittent signals. The user can use spectrogram to analyze the stability
of a signal over the time, or to identify intermittent interference signals
in communications systems. There are two markers for the user to identify power
versus frequency and time. Also the time interval between two consecutive colored
rows can be adjusted. When a marker is put on the spectrogram, the N9340B can
display the trace for the time of the selected marker. The spectrogram data
and screenshots can be saved and recalled for later analysis or reporting.
Field strength measurement
Electric field strength measurements are frequently required for field
testing of transmitter and antenna coverage. Field strength measurements are
now a standard function in the N9340B. Calibrated field strength measurements
are easy to make once the antenna factors are loaded into the analyzer via
the provided PC software based antenna template. Either field strength (in
dBµV/ m, dBmV/ m, or V/ m) or power flux density (in dBm/ m or W/ m ) can be
displayed. With the amplitude offset function, the user can correct gain or
loss. And finally together with the user-definable multi-limit line function,
the N9340B offers the user quick and convenient field strength measurements
and analysis.
High accuracy power measurement
The N9340B now supports high-accuracy, USB plug-and-play power measurements
as standard when connected to an Agilent U2000 series USB power sensor. Make
true average power measurements for all signal types with wide dynamic range
up to 18 GHz with just the push of a button. The Agilent U2000 USB sensors
require no external power supplies and with internal zeroing eliminate the
need for external calibration. Without the need for additional boxes, the user
can easily set up, calibrate and control the power meter/sensor via the analyzer’s
USB port. The N9340B can collect, display and save the power meter results.
The analyzer also provides Pass/Fail testing with user set upper and lower
limits and a Pass/Fail indicator. Test results are shown in dBm and W when
making absolute measurements and in dB and percentage when measurements are
relative. Two display modes are available: Meter or the Chart mode to log power
measurements over time.
AM/FM modulation analysis (Option AMA)
Optional AM/FM modulation analysis shows the metrics you need, including
carrier power, modulation rate, AM depth/FM deviation, SINAD and carrier frequency
offset. User definable limits provide Pass/Fail indicators in 4 cases: higher
than carrier power, larger than AM modulation index or FM deviation, lower
than AM modulation index or FM deviation, or larger than carrier frequency
offset. The user can save the waveforms with metrics for reporting as well
as the set-up parameters for future measurements or analysis.
ASK/FSK modulation analysis (Option DMA)
Optional ASK/FSK modulation analysis is now available. Amplitude Shift
Keying (ASK) is used in RFID and optical systems. Frequency Shift Keying (FSK)
is used in many applications including cordless phone, paging systems and RFID.
N9340B w/option DMA supports 4 display modes: Symbol, Waveform, ASK/FSK Error,
and Eye Diagram. Included is Pass/Fail testing of higher than carrier power,
higher than ASK modulation depth/FSK frequency deviation, lower than ASK modulation
depth/FSK frequency deviation and higher than FSK frequency deviation. The
metrics you need are shown, including carrier power, ASK/FSK error, ASK depth/FSK
frequency deviation, and ASK index etc. For reports and future measurements
the waveform with metrics and setup parameters can be saved.
Channel table
For the users who prefer to tune the spectrum analyzer according to channel
numbers rather than center frequency, you will find the new Channel Table feature
easy-to-use. The Channel Table includes the major wireless communication standards,
such as AMPS, GSM/EDGE/GPRS, CDMA, CDMA2000 etc. The Channel Table can also
be edited by the user with the included N9340 PC Software. The revised Channel
Table can be downloaded to the analyzer via a PC USB cable or a USB memory
stick.
Safety at high input levels
The N9340B can be used for most cases. However, should the power level
exceed 33 dBm, the input protection switch activates to protect the instrument
from damage. The maximum safe input level is > +33 dBm for 3 minutes at
most (50 VDC).
One-button measurement
The Agilent N9340B supports one-button measurements of occupied bandwidth,
channel power and adjacent channel power ratio. This virtually eliminates set-up
time in the field.
Occupied bandwidth (OBW)
An occupied bandwidth measurement integrates the power of the displayed
spectrum and puts one pair of vertical lines at the frequencies between which
the interested signal is contained. An N9340B spectrum analyzer supports two
ways to measure the occupied bandwidth, in percentage or in dBc.
Channel power
Use channel power to measure both power and power spectral density in
a user-specified channel bandwidth. One pair of vertical lines on the display
indicates the edges of the channel bandwidth.
Adjacent channel power ratio (ACPR)
Wireless service providers need to minimize the interference caused by
power leaking into adjacent transmit channels. Adjacent channel power ratio
measurements help in checking of signal spectrums and in identifying and controlling
sources of interference.
See traces clearly indoors and outdoors
As with all the newest Agilent portable field testers, operating under
challenging bright sunlight or other difficult natural lighting conditions
is no problem. The unusual 6.5"
TFT display with resolution of 640 x 480 pixels provides a superior, bright
and clear trace for indoors and outdoors use. There is no need to ensure you
operate in the shade. The N9340B has a light sensor in the front panel. The
light-sensor can be activated to adjust the display brightness to adapt N9340B
to the changing lighting conditions. |
