The 2382 Fig. 1 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 c.r.t. Further
facilities such as the display of a modulated signal, the
recovery of a modulating signal, the provision of a tracking
generator etc. are also available.
2. The design of the 2382 incorporates many original and
sophisticated features. This extends its application in
areas such as :
• Testing of h.f. and v.h.f. transmitters and receivers
• Interference monitoring
• Signal source purity measurements
• Commissioning communication systems
9 PCM and FDM system measurements
• Measurements on CW, FM, and AM signals including :
non-linear modulation hum sidebands spurious FM on AM
carrier frequency modulation frequency deviation/modulation
• Displaying the characteristics of active and passive
networks - filters, amplifiers etc.
3. The instrument is a microprocessor controlled swept tuned
analyzer of the superheterodyne type. It comprises a lower
unit (2382) containing a frequency synthesizer and swept
receiver, and an upper unit (2380) containing the display,
digital processing and power supply. The c.r.t. has a
viewing area of 140 mm x 110 mm. A minimum of multifunction
front panel controls have been used for simplicity and ease
4. The display is scaled in both frequency and amplitude for
absolute and relative measurement - advanced circuit design,
digital error correction and automatic self calibration give
a reference level accuracy of ±1 dB.
5. For optimum control the operator may set the reference
frequency, span, and reference level using either a keypad
or dedicated rotary controls. Full GPIB talk and listen
facilities are also provided.
