The 2683 from BK Precision is a spectrum analyzer that operates from 9 kHz to 3.2 GHz. It has a high sensitivity of -161 dBm/Hz, a low phase noise of -98 dBc/Hz, and a low-level uncertainty of +/- 0.7 dB. This spectrum analyzer delivers performance and functionality in a lightweight, compact design that is suitable for lab and field use. It has a minimum resolution bandwidth (RBW) of 1 Hz. It incorporates a 10.1” wide-screen 1024 x 600 color display to visualize the waveform and make precision measurements such as third-order intercept, occupied bandwidth, 2D and 3D spectrum monitor. It supports LAN and USBTMC connectivity and has a USB host port to store and recall waveform data, setups, and screen captures. These spectrum analyzers are ideal for applications in 2-way radio, site surveying, EMI pre-compliance, and characterizing the frequency response of RF devices.
