Generator boosts stability and
sensitivity
The TG550 function generator from TTi has been re-engineered to give greater frequency stability and improved sensitivity for the built-in external counter.
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 benchtop case, the TG550 is a 5MHz analogue function generator which incorporates a digital measurement and control system to lock the frequency to a reference

Function generator has accuracy locked in
A new 5MHz function generator incorporates a digital frequency locking system that gives it a level of frequency stability that cannot be matched by conventional analogue function generators.
Compact bench power supply provides 175W
The EX355, new from TTi (Thurlby Thandar Instruments), is a single-output laboratory DC power supply providing an output from 0 to 35V at 0 to 5A.
Programmable power-supplies offer outputs to 1kW
The XHR range of programmable power supplies, offering output ratings up to 1 kW is power-factor corrected for low current draw and reduced generation of input current harmonics.
The generator provides simultaneous digital display of frequency and level.
A large LCD 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 that uses 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 10ppm, and an external adjustment point allows recalibration when high accuracy is essential.
A measurement period of 0.5 or 5s 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 20s.
AM capability is also incorporated, with a choice of internal or external modulation from 0 to 100%.
The TG550 costs GBP 356 (plus VAT) in the UK.
