Keysight (Agilent) N9344C Handheld Spectrum Analyzer, 1 MHz to 20 GHz

The Keysight N9344C is a handheld spectrum analyzer delivering benchtop performance across 1 MHz to 20 GHz in a rugged, fanless, field-portable package. Weighing 3.6 kg with MIL PRF 28800 Class 2 compliance, it operates in demanding environments from -10 to 50 °C. The 6.5-inch transflective LCD display remains readable in daylight and low-light conditions.
