N9340B superior performance ensures the field test confidence • Superior sensitivity: Lowest DANL in-the-class • Fastest sweep time • Narrowest resolution available • Frequency range: 100 kHz to 3 GHz (tunable to 9 kHz) 1 • DANL: (RBW = 30 Hz, 10 MHz < fc ≤ 1.
N9340B applications for field test • Aerospace and defence: Radio and radar test, interference analysis, on-site repair • Wireless service providers: Interference analysis, on-site repair • TV and broadcasting: Interference analysis, channel power check • Spectrum management authority: Spectrum monitoring N9340B is now equipped with powerful features to address field applications using a handheld spectrum analyzer. An analysis is identifying interfering signals.
Extended spectrogrammonitoring (Option INM) Option INM extends the N9340B spectrogram capability further with the ability to continuously monitor and save spectrogram data over time not only to the analyzer’s internal memory or a USB flash drive, but also directly to a PC. With option INM users can save more than 1,500 continuous frames of data depending on the size of the USB flash drive or PC memory. Option INM also supports an Automatic Save function.
DSL measurements (Option XDM) xDSL (ADSL and VDSL) is widely used for broadband internet connections at homes and businesses. Service providers occasionally face problems with interference on their xDSL lines. The interference is mainly intermittent intrusion from nearby external sources such as electric motors, elevators, and appliances. In order to monitor, capture and remove intermittent interference, the engineer may need to work in the field for extended periods of time.
IBOC measurements (Option IBC) N9340B IBC also supports a onebutton auto-tune function that greatly simplifies the otherwise complex user setup required to capture and measure IBOC signals of interest. The auto-tune function will automatically set the frequency span, RBW, Average and Detector types, etc. It only takes seconds for the auto-tune function to display the correct measurement results.
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.
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. It is quick and easy to set center frequency integration bandwidth, and channel bandwidth. Adjacent channel power ratio (ACPR) Wireless service providers need to minimize the interference caused by power leaking into adjacent transmit channels.
Spectrum emission mask (SEM) The new N9340B adds Spectrum Emission Mask (SEM) as a standard feature. SEMis a mask for out-of-channel emissions measurement. The SEMis defined relative 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.
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.
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 system and RFID. N9340B with option DMA supports 4 display modes: Symbol, Waveform, ASK/FSK Error, and Eye Diagram.
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.
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.
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.
