The IFR FM/AM-1100A Communications Service Monitor is a digitally synthesized AM/FM/SSB receiver and signal generator. All components within the unit are solid state, with the exception of the CRT and several switches. The receiver is a quadruple conversion receiver, capable of receiving communication signals from 300 kHz to 999.9999 MHz. The signal generator is capable of generating modulated or unmodulated signals from 1 kHz to 999.9999 MHz. Specifications. RF Signal Generator Frequency Range: 100 Hz to 999.9999 MHz in 100-Hz steps. Frequency Accuracy: 5 x 10^-7 (±0.00005%). RF Output Power: -130 dBm to -35 dBm (1 kHz to 1 GHz). RF Output Power Accuracy: -110 to –35 dBm ±2.5 dB to 400 MHz, ±3.0 dB above 400 MHz. Oscilloscope Vertical Bandwidth: DC to 1 MHz (at 3-dB bandwidth). Horizontal Sweep Rate: 10 ms, 1 ms, 0.1 ms, 0.01 ms per division. Audio Generator Frequency Range: 10.0 Hz to 20 kHz (Variable Tone), 1 kHz (Fixed Tone). Receiver/Monitor Frequency Range: 300 kHz to 999.9999 MHz. Resolution: 100 Hz. 10 dB Sinad Sensitivity: 2 µV (typical). Power Monitor Frequency Range: 1 MHz to 1000.00 MHz. Power Ranges: 0 to 4, 0 to 40 and 0 to 400 watts.
