The 3586C selective level meter finds applications in general- purpose wave analysis for the design, manufacture, and maintenance of electronic systems. The HP 3586C is fully HP-IB programmable and covers the frequency range of 50 Hz to 32.5 MHz. This allows you to measure audio, sonar, and other low-frequency systems, as well as high-frequency communications subsystems. The HP 3586C provides input impedances of 50,75,and 600 fa with 10 kfl bridging for maximum measurement flexibility in a wide variety of applications. Measure signal levels with up to ± 0.2 dB accuracy down to --80 dB, with 0.01 dB resolution and bandwidth choices of 20,400,or 3100 Hz. The built-in counter and narrow-resolution bandwidths allow harmonic and intermodulation measurements to be made with ease. Frequency can be set or measured with 0.1 Hz resolution and 10 ppm stability (± 0.2 ppm optional)).
