Agilent Technologies has introduced
the 100-kHz to 7-GHz (tunable to 9
kHz) N9342C HSA (handheld spectrum
analyzer), which targets engineers
and technicians who install, maintain, and
monitor the performance of RF systems in
the field. The new unit provides broader
frequency coverage and more features
than earlier members of the manufacturer’s
HSA family. To simplify making quick,
accurate, and repeatable measurements
under difficult field conditions, the 7.5-
lb, 12.5×8.15×2.7-in. N9342C provides
user-customizable capabilities.The instrument targets use in aerospace/ defense, microwave, satellite, wireless-communication, broadcasting, spectrum-regulation, and general-purpose spectrum-analysis applications. Measurements include transmitter and component test, receivingpath signal monitoring, and antenna tuning. RF-environment measurements include band clearance, signal coverage, and interface hunting. A task-planner feature automates routine measurements, reducing test-setup time by 95%, thereby increasing efficiency.
The HSA provides a set of standard, one-button measurements, including occupied bandwidth and in-channel and adjacent-channel power, which help you to characterize signal quality. The keypad design allows access to most measurement functions with no more than two button presses.
A rugged, fanless design suits the unit for challenging field environments, and an optional three-in-one ergonomic backpack ensures comfort and provides true hands-free operation. Moreover, with the LCD’s automatic brightness adjustment and the keypad’s backlight control, you can easily view the instrument’s screen and enter measurement parameters by day or night.
You can use free HSA PC software to remotely control the instrument through a USB (Universal Serial Bus)/LAN connection. The device also has a dedicated user key, a customizable frequency and channel table, and frequency and amplitude correction.
Key N9342C options include a built-in 7-GHz tracking generator, a built-in GPS (global-positioning-system) receiver and antenna that provide precise location information, a spectrum monitor with spectrogram record and playback functions, support for the manufacturer’s U2000 USB power sensors that offer high-accuracy power measurement to 24 GHz, a user data-sanitization feature for security purposes, an 8-GHz directional antenna that enables users to hunt for interference, and a built-in power connector for an active RF probe that ensures precise in-circuit measurements. The N9342C HSA’s US base price is $11,113; a typical configuration costs $12,567.
