Station Monitor

Information

1. Station Monitor SM-220 is designed specifically for measurement of the TS-820 and TS-520 series SSB transceivers. 2. The unit is comprised of a monitor-scope, oscilloscope and two-tone audio generator. A Pan Display option is also available. 3. The monitor-scope will display transmitted waveform from 1.8 MHz to 54 MHz, 5W-2 KW PEP, and to 150 MHz, 100W PEP. Drive input terminals permit trapezoid waveform observation. 4. The oscilloscope features high sensitivity (better than 20 mV/DIV) and wide bandwidth (2 Hz — 10 MHz), and makes possible measurement of various waveform types. Receiver IF can be dispalyed directly from the TS-820S IF-OUTPUT terminal. 5. The two-tone audio generator provides 1000 Hz and 1575 Hz tone individually or simultaneously. 6. A plug-in Pan Display is available as an option: For the TS-820S, specify the BS-8, or for the TS-520S specify the BS-5, 7. Horizontal trace tilt can be adjusted from the rear of the unit without removing the case. 8. The blue-green (B-31) phosphor CRT assures excellent brightness and contrast for extended fatigue free viewing. 4
