• Notes

• Marconi’s TF867 has been a standard for many years but it is now tending to be replaced by their transistorised TF2002. This instrument gives high-quality amplitude-modulated output in a carrier range from 10 kHz to 72 MHz.
  It displays the low. drift, low signal leakage, and lack of spurious modulation to be expected in good standard signal generators. Communications engineers often have a requirement for very low-level RF signals and the TF2002 meets this with an output variable down to 0.1 µV.
  The internal modulation is variable from 20 Hz to 20,000 Hz a depth continuously variable up to 100 %.

  Coverage: 10 kHz to 72 MHz in 8 ranges, RF_out min. 1 V_eff, built-in AF generator 20 Hz to 20 kHz in 6 ranges, two built-in meters, linear band scale.
