General Notes

Note

The DOSY TC-4001 Test Center is a diagnostic tool designed to measure the performance of radio transmitter systems. It provides real-time readings for power output (in watts), Standing Wave Ratio (SWR), and modulation percentages for both AM and SSB modes. The device features a multi-scale analog meter and several manual controls to ensure accuracy across different power levels. Supports both RMS and Peak power measurements and includes specialized settings for testing AM and Single Side Band (SSB) modulation. Wattage Ranges: 20, 200, 2000, and 4000 Watts Modulation: AM (percentage) and SSB (on specialized lower scale) Power Modes: RMS and PEAK Operating Notes When using Grounded Grid amplifiers, it is recommended to check AM modulation at the transmitter or with the amplifier in standby, as feed-through power can prevent the grounded grid from reaching 100% modulation.
