Sweep generator TF 2361

The TF-2361 Sweep Generator is a general-purpose instrument with a wide range of applications.

The main unit generates a sweep voltage which is used to drive a plug-in oscillator; several different plug-in oscillators are available, covering different frequency ranges. The main unit houses the power supplies for the complete instrument and has front panel controls which enable the sweep voltage to be driven externally or internally, locked to the mains frequency or a television frame scan, or controlled manually. Other facilities include a blanking generator, a maker adder, and an x-Drive output for an associated oscilloscope, display unit, or chart recorder.

The operational modes are selected by a front panel sweep function switch. This gives a range of internal sweep drive from 0.01 Hz to 100 Hz in four decades, mains lock to mains frequencies from 45 to 400 Hz. TV lock to frame scan on 405, 525, or 625 line composite TV signals, external control by signals from DC to 20 kHz, a CW mode in which the instrument behaves as an ordinary signal generator, and a manual mode in which a control is used to manually sweep over arrange of frequencies set up in the plug-in oscillator.
The ratio of sweep to flyback can be set at 1:1 or 10:1, and on internal ranges, the instrument can be set to give a single sweep when a “one-shot” operation is required.

In the mains lock and TV modes, a phase shift control allows the swept frequency to be positioned so that high or low frequencies are applied to any part of the spectrum being examined.
