The TGR2050, new from TTi, is a low cost, synthesised 150kHz to 2GHz signal generator which incorporates the essential features required for most RF development, test and service work, namely frequency accuracy and stability, wide dynamic range, low phase noise and low leakage.

It offers AM, FM and Phase modulation using either an internal or external source. Wide modulation range and low distortion make it suitable for most modulated signal test procedures within the 150kHz to 2000MHz spectrum.

The TGR2050 sets a new price standard for a high performance RF generator. New manufacturing techniques utilising the latest component technologies have significantly reduced costs, making it possible for every engineer involved in RF design, manufacture or testing to have a generator of their own.

The generator uses a fully synthesised source locked to a temperature compensated crystal oscillator, providing frequency stability of better than 1ppm over a 15oC to 25oC temperature range and an ageing rate better than 1ppm per year. Where yet higher accuracy and stability are required, the generator can be locked to an external 10MHz frequency standard.

Frequency can be set to a resolution of 10Hz across the whole frequency range giving a peak setability of 0.005 ppm. Frequency steps can be set to any value and stepping can be done with up/down keys or the rotary encoder. This frequency stepping system makes operations such as precise amplitude response characterisation particularly easy.

The TGR2050 provides an amplitude range of -127dBm to +7dBm (01V to 500mV into 50W). Setting resolution is 0.1dBm or 0.01V. Output level steps can be set anywhere between 01dBm and 100dBm (or 001V to 100mV depending on the entry mode). Stepping the level is useful for quick assessment of circuit linearity and dynamic range for instance.
The advanced attenuator design provide excellent flatness over the whole frequency range.
Meticulous internal screening provides very low output leakage enabling accurate low level measurements in sensitive circuits such as receivers.

The generator provides full remote control facilities for all its functions via both RS-232 and GPIB (IEEE-488.2) interfaces. In addition it can store nine full instrument set-ups in non-volatile memory. This allows repetitive testing procedures to be undertaken quickly and accurately.

The TGR2050 incorporates a four line, eighty character backlit display, numeric entry keypad and rotary encoder. The compact casing measures 130 x 212 x 330 mm (half-rack width by 3U height) and the weight is 4.6kg.

The TGR2050 costs 2,990 in Europe, 2,290 plus vat in the U.K.
The approximate International price is $3,000.
