Advanced design techniques utilising the latest component technologies have made this possible. The TGR2050 offers AM, FM and Phase modulation using either an internal or external source. The low cost makes it possible for every engineer involved in RF design, manufacture or testing to have a generator of their own. High Precision and Stability The TGR series uses a fully synthesised source locked to a temperature compensated crystal oscillator. This provides excellent signal frequency stability against temperature and ageing. The TGR2050 adds the further capability of locking to an external 10MHz source. The frequency can be set to a resolution of 10Hz across the whole frequency range (1kHz resolution on TGR1040). Frequency steps can be set to any value and stepping can be done with up/down keys or the rotary encoder. The frequency stepping system makes operations such as precise amplitude response characterisation particularly easy. Wide Amplitude Range & Low Leakage The TGR series provides an amplitude range of -127dBm to +7dBm (0*1V to 500mV into 50W). Setting resolution is 0.1dBm or 0.01V. Output level steps can be set anywhere between 0*1dBm and 100dBm (or 0*01V 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. Overview TGR Series The TGR series are low cost, synthesised RF signal generators that incorporate the essential features required for most development, test and service work; namely high frequency accuracy and stability, wide dynamic range, low phase noise and leakage, and flexible modulation capabilities. u The TGR2050 covers from 150kHz up to 2GHz and incorporates AM, FM and Phase modulation (internal and external). The wide frequency range and comprehensive modulation capabilities make it suitable for most tasks within the 2GHz spectrum. u u u u u u The TGR1040 has a more restricted frequency range of 10MHz to 1GHz and incorporates FM modulation only (internal and external). It retains the high stability and wide amplitude range of the 2050 making it suitable for many task including FM radio receiver sensitivity measurements, system gain measurements, receiver tuning & alignment, oscillator substitutions, EMC/antenna/field strength measurements and as a signal source for many other RF circuit and system development tasks. u Both instruments can be operated using either numeric or rotary controls, and can be remotely controlled via either an RS-232 interface or GPIB interface. Nine memories are provided for user set-ups. u u u u u Setability of 10Hz at up to 2GHz (TGR2050) Accuracy better than 1 ppm over 15 oC to 30 oC Ageing better than 1 ppm over one year External frequency locking (TGR2050) Low phase noise and low leakage Amplitude range of -127dBm to +7dBm Amplitude entry in dBm or V / mV Amplitude setability of 0.1dBm or 0.01V FM, Phase and AM modulation (TGR2050) Direct numeric entry or rotary control with user setable frequency/amplitude increments Non-volatile storage for 9 generator set-ups Full remote control via RS-232 or GPIB Unmatched price/performance ratio Meticulous internal screening provides very low output leakage enabling accurate low level measurements in sensitive circuits such as receivers. Ease of use The TGR series incorporates a simple and straightforward user interface. The back-lit four line display shows all the major signal parameters simultaneously. Data can be entered numerically using 0 - 9 keys or can be incremented/decremented using up/down keys or the rotary encoder. Both frequency and output level can be adjusted in steps of user programmed size. Output level can be set either in dBm or linear units of V or mV. A single button press will translate from one to the other. The TGR series can store nine full instrument set-ups in non-volatile memory. This allows repetitive testing procedures to be undertaken quickly and accurately. Full remote control The TGR series provides full remote control facilities for all its functions using both RS-232 and GPIB (IEEE-488.2) interfaces. (GPIB is an option for the TGR1040). Wide modulation range and low distortion make the TGR2050 suitable for most modulated signal test procedures. The TGR1040 provides FM modulation only using either an internally generated modulator signal or an external signal in the range 300Hz to 50kHz. This wide bandwidth allows for audio band demodulator testing as well as LF digital modulation.
