Identifying interference
Whether it’s created by nature or man-made, intentional or inadvertent, signal interference means restoring communication integrity is the top priority. For any type of communication system - voice, video, or data - identifying and analyzing the source of interference is predicated on getting accurate, reliable results. Now you have confidence provided by a benchtop signal analyzer in a form factor that fits in your hand. That assurance helps you quickly eliminate the possibility of system malfunctions, isolate interference timing, repetition, and duration patterns, and characterize the interfering signal so that you can identify and mitigate it. All of this allows you to restore system quality quickly. Keysight’s economically - priced HSA family offers a variety of features that make identifying interference faster, easier, and more reliable:
Two spectrogram markers display frequency, amplitude, and time information.
Audio alerts indicate signal strength in a specified frequency range
Fast sweep speeds and triggering support location of bursted or intermittent signals
Optional spectrogram display, record, and playback features create a powerful analysis tool for understanding spectrum
One - button shortcut that adjusts the HSA for best sensitivity
An AM/FM tune and listen feature for listening to interfering AM/FM analog signals.
Up to four traces can be simultaneously displayed with various detectors, including MAX and MIN hold
Optional built-in tracking generator measures two-port transmission of filter and amplifiers to validate your system is working correctly before you begin evaluating sources of interference
When interference is intermittent, the capability to perform remote system monitoring is valuable. Using the N934X spectrum analyzer as a sensor, you have the ability to start and stop data collection at predetermined dates and times. With the ability to monitor spectrum spanning large areas, in inhospitable or remote locations, or collect data for an extended period of time, the Keysight HSAs are ideal for use by government security agencies and military agencies, in addition to private sector installations, such as commercial broadcast. Keysight N934X HSAs offer a variety of features that make remote signal monitoring faster, easier, and more reliable:
Control over LAN allows remote control and data transfer.
USB port allows for convenient data storage to USB memory sticks or other storage devices.
Optional spectrogram records up to 1,500 traces to capture events for later diagnosis
Optional channel scanner displays and records channel power for up to 20 different channels
Fast sweeps capture bursted or intermittent rogue signals
AC and DC power operation enables use in a variety of locations
Easy export of data and traces via LAN or USB
Locating sources of unwanted or unexpected signals
Protecting your system spectrum from unwanted or unexpected signals is essential. A multi-function spectrum analyzer is indispensable for expediently pin-pointing an undesired source. The Keysight HSAs have the spectrum analyzer features you need in a convenient, portable package. These capabilities are particularly important to government agencies, the military, and industries needing to quickly identify the source of an RF or microwave signal.
Keysight’s economically - priced HSA family offers a variety of features that makes locating sources of signals faster, easier, and more reliable:
Fast sweep speeds and triggering, along with directional antenna, supports location and direction of bursted, intermittent, or continuous signals
Narrow RBW and best-in-class dynamic range help find small hidden signals in the presence of large ones
Optional internal GPS receiver and antenna provides precise location information and automatically stamps the GPS coordinates on each trace.
Optional directional antenna expedites signal location and audio alert indicates signal location.
Optional backpack, neck strap, and carrying case enable hands-free operation of the HSA allowing users to hold a directional antenna and communication device when searching for signals.
Multiple markers and the marker table simplify simultaneous tracking of multiple signals of interest
Site survey and mapping
Prior to the installation of new cellular or wireless communication networks, radio station towers, WiFi networks, smart grid networks, hospital RF systems, private mobile radio systems, or military communication systems, site surveys are critical. When your job is to develop a spectral baseline for the area, an HSA in the palm of your hand makes it easier for you to identify multipath effects, noise floor level, line-of-sight opportunities, or the need for spectrum clearing. Keysight’s HSAs automatically record GPS coordinates, make field strength measurements in dBµV/meter, record the results, and have the ability to identically perform these functions for every sector. The capability to quickly download measured data to generate a field strength map report that documents the spectral characteristics of the area is an added bonus.
