Function generator's improved frequency
stability
5MHz analogue function generator incorporates a digital measurement and control system to lock the frequency to a reference
The TG550 function generator from TTi has been re-engineered to give greater frequency stability and improved sensitivity for the built-in external counter Housed in a new 2U high bench-top case, the TG550 is a 5MHz analogue function generator which incorporates a digital measurement and control system to lock the frequency to a reference

The HA 1600 from TTi is upgraded to incorporate both Amendment 14 to the harmonics legislation standard (EN61000-3-2), and extra flicker measurement capabilities to EN61000-3-3
The generator provides simultaneous digital display of frequency and level.
A large LCD display shows frequency in the left-hand half and output level in the right-hand half.
The output level display can be selected to show any of three values: peak-to-peak amplitude, RMS amplitude, or DC offset.
The decimal point and units are changed automatically, resulting in a display of the true amplitude regardless of the attenuator setting.
The TG550 has an external counter mode which utilises the full width of the display to provide up to seven digits of resolution.
The frequency range is from 5Hz up to 20MHz, and the input sensitivity is better than 40mV RMS.
Accuracy is typically better than ten parts in 10^6, and an external adjustment point allows re-calibration when high accuracy is essential.
A measurement period of 0.5 or 5 seconds can be selected.
Reciprocal counting ensures high resolution regardless of input frequency, allowing, for example, mains frequency to be measured to a resolution of 0.001Hz.
The TG550 generates sine, square, triangle, pulse and ramp waveforms from 0.005Hz up to 5MHz.
A built-in sweep generator provides linear or logarithmic sweeps with periods ranging from 20ms to 20 seconds.
AM capability is also incorporated, with a choice of internal or external modulation from 0 to 100%.
The TG550 costs £356 (plus VAT) in the UK.
