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
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 (0·1µV to
500mV into 50W). Setting resolution is 0.1dBm or 0.01µV. Output level
steps can be set anywhere between 0·1dBm and 100dBm (or 0·01µV 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
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.
