  SlGNAL INJECTOR, Type SIM-212 Code: 4822 395 30066

  Description:

  With the aid of this signal injector faults can be quickly located both in L.F. amplifiers and in radio, black-and white and colour-TV receivers. The injector contains a sine-wave oscillator which on delivery is tuned to the frequencies 5.5 MHz and 4.43 MHz.
  This oscillator is modulated with the aid of a multivibrator supplying a square-wave voltage with a frequency of approx. 300 Hz. The output voltages of the injector can be varied continuously by means of one control.

  Putting the injector into service

  - For changing over to other frequencies, see " adjusting the injector".
  - For the high frequencies 5.5 MHz and 4.43 MHz the test probe must be inserted into socket ∿∿ for the low frequency into socket ∿.
  - Set switch F1 - F2 (B) to position F1 for 4.43 MHz and to position F2 for 5.5 MHz.
  - Now inject the signal selected on the appropriate spot in the unit to be repaired (connect the earth lead to the chassis).
  - Push the button for switching on the injector (D) .
  - With the aid of control (A) the intensity of the signal can be varied.
  - lf the 300-Hz signal should have to be injected (test probe in position ∿ ), the position of switch F1 - F2 is irrelevant.

  The H.F. signals can be used for tracing faults in:

  - The audio I.F. section of black-and-white and colour-TV receivers (F2 : 5,5 MHz).
  - The video I.F. section and channel selectors of black & white and colour-TV receivers (harmonics of F1 – 5.5 MHz or F2 – 4.43 MHz).

  Adjustment of the injector:

  E.g. the injector must be adjusted for SECAM:
  - lnterconnect F. and G.
  - Set control A to maximum signal.
  - Set the injection pin to positions ∿∿ (H.F.).
  - Set switch F1 - F2 to position F1.
  - Inject a signal into the input of the sound I.F. section of a television receiver.
  - Adjust the care of coil L 1 to maximum signal.
  - Set switch F1 - F2 to position F2.
  - lnject a signal into the input of the first I.F. section (output of channel selector) and adjust C7 to maximum picture (turn the control A slowly back during adjusting, so that the picture is on the verge of showing noise).
  The same adjusting method can be used for the other systems.
