Marconi TF2005R Two Tone Source

Description

This equipment has been tested. Please refer to the tests/remarks section below for details.

SERIAL NO: N/A

MANUFACTURER DESCRIPTION:

2x  TF2005R AF Oscillators + 1x 52005-301D Monitored Attenuator.

To provide 1ow distortion signals for determining the intermodulation distortion in amplifiers, or (using one oscillator only) for general purpose testing.

The TF2005R is a nice two-tone oscillator for intermodulation testing of audio amplifiers and the like.

Each low distortion oscillator covers the frequency range 20 Hz to 20 kHz. They can be used independently or in combination. The output can be attenuated in steps of 0.1 dB using the built in 600 ohm attenuator.

Connections between the modules is achieved by the use of coaxial patch connectors at the rear of the unit, which is presented as a single 19″ rack mounting instrument.

This well made and reliable instrument was made in the 1970s and is in as-new condition.
