TG550 - 5MHz Advanced Function Generator

  0.005Hz to 5MHz frequency range
  Built-in 7 digit frequency counter
  Digital frequency lock for exceptional stability
  Simultaneous display of frequency and voltage
    amplitude or offset
  Internal/external AM up to 100%
  Precision internal lin/log sweep  

The TG550 represents the state-of-the-art in 5MHz analogue function generators. It provides very high waveform quality at all frequencies and levels.
The large LCD display provides a digital readout of both frequency and level (peak-to-peak amplitude, rms amplitude or dc offset).

Advanced measurement techniques are used to provide high accuracy with fast update even at low frequencies.

An external counter mode is available which utilises the full width of the display to provide up to seven digits of resolution. A reciprocal counting measurement system is used which ensures high resolution regardless of input frequency. Thus, for example, mains frequency can be measured to a resolution of better than 1mHz.

The TG550 includes a digital frequency locking system that gives it a level of frequency stability that cannot be matched by conventional analogue function generators.

Once the frequency has been set, pressing the Lock key engages a measure-and-correct circuit which compensates for the small thermal and mechanical drifts that inevitably occur in an analogue generator.

The frequency is compared to a crystal controlled reference and is maintained to within 0.01% of the set frequency.
