N9340A Overview 1

4Power Suite

Provides one- button measurement functionality on OBW (Occupied Bandwidth), channel power, and ACPR (Adjacent Channel Power Ratio).

5High- sensitivity measurement

Includes a 3 GHz pre- amplifier (Option N9340A- PA3) enabling highly sensitive measurement which helps in the analysis of low- level signals.

Optimized Usability

An Agilent N9340A handheld spectrum analyzer provides enhanced usability:

•7.2- inch sunlight viewable screen ( 640 ⋅ 480 pixels) enables you to read the scans easily and clearly in sun light.

•Arc- shaped handle and rugged rubber casing ensure a comfortable and firm hold and ruggedness.

•One- button measurement function provides an easy, fast access to power measurement.

•File saving or loading via USB interface.

•Instant screen control for power saving: pressing and holding [Preset] hardkey for over two seconds turns off the screen. Pressing any key on the front panel activates the screen.
