• Notes

• AM signal generator providing CW, sine AM and pulsed output in the frequency range of 10 to 470 MHz, in 5 bands:

  • A = 10 - 22 MHz
  • B = 22 - 48 Mhz
  • C = 48 - 110 MHz
  • D = 110 - 260 MHz
  • E = 260 - 470 MHz

  Outputs:

  • Continuous Wave
  • Sinewave Modulation: internal (1 kHz) or external (30 Hz to 20 kHz) 0 to 90 %
  • External Source: between 30 Hz and 20 kHz
  • External Pulse Modulation
  • External Squarewave Modulation.

  RF output level from 0.1 µV to 1 V on 50 Ohm. Crystal calibrator for CW operation.

  The manual for devices with serial number JA502/001 and above dates from 7/1960. Some models have valve V11 (EA76) replaced by diode OA202.
