FEATURES The 2382 is an exceptionally versatile general purpose Spectrum Analyzer for use from 100 Hz up to 400 MHz. Although simple to operate it has many functions which make it an indispensable tool in research, development, production, installation, commissioning and maintenance. It analyzes signals by separating them into their frequency components and the power or voltage level of each is displayed as a function of frequency on a CRT screen. Facilities such as the display of a modulated signal, the recovery of a modulating signal and the provision of an integral tracking generator for swept frequency measurements further enhance its capabilities. The design of the 2382 incorporates many original and sophisticated features. This extends its application in areas such as : • Testing of HF and VHF transmitters and receivers • Interference monitoring • Surveillance • Signal source purity measurements • Commissioning communication and radar systems • Measurements on CW, FM, and AM signals including : non-linear modulation hum sidebands spurious FM on AM carrier frequency modulation frequency deviation/modulation depth • Displaying the swept frequency characteristics of active and passive networks -filters, amplifiers etc. The instrument is a microprocessor controlled swept tuned analyzer of the superheterodyne type. It comprises a lower unit (2382) containing frequency synthesizers, the swept receiver and tracking generator, and an upper unit (2380) containing the display, digital processing and power supply. The CRT has a viewing area of 140 mm x 110 mm. The display is scaled in both frequency and amplitude for absolute and relative measurement - advanced circuit design, digital error correction and automatic selfcalibration give a reference level accuracy of ±1 dB. For optimum control the operator may set the reference frequency, span, and reference level using either a keypad or dedicated rotary controls. RF attenuation, video bandwidth, sweep time and resolution bandwidth are set automatically but settings may be simply overridden using dedicated increment keys. Full GPIB talk and listen facilities are also provided.
