2GHz Full Performance RF Generator Under 3000 Euro

The new TGR2050, developed and manufactured in the UK by TTi (Thurlby Thandar Instruments), is a low-cost synthesised 150 kHz to 2 GHz signal generator for most RF development.

The new TGR2050, developed and manufactured in the UK by TTi (Thurlby Thandar Instruments), is a low-cost synthesised 150 kHz to 2 GHz 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.

The new instrument 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 150 kHz to 2000 MHz 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 one part per million over a 15C to 30C temperature range and an ageing rate better than one part per million per year.

Where yet higher accuracy and stability are required, the generator can be locked to an external 10 MHz frequency standard.

Frequency can be set to a resolution of 10 Hz across the whole frequency range, giving a peak 'setability' of 0.005 parts per million.

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 -127 dBm to +7 dBm (0.1 uV to 500 mV into 50 ohms).

Setting resolution is 0.1 dBm or 0.01 uV.

Output level steps can be set anywhere between 0.1 dBm and 100 dBm (or 0.01 uV to 100 mV depending on the entry mode).

Stepping the level is useful for quick assessment of parameters such as circuit linearity and dynamic range.

The advanced attenuator design provides excellent flatness over the whole frequency range.

Meticulous internal screening provides very low output leakage, enabling accurate low-level measurements to be made 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 4-line, 80-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 4.6 kg.

The manufacturer's recommended price is Euro2990.
