Costing little more than an analogue generator, it has the precision of a synthesised generator. Advanced design techniques utilising the latest component technologies have made this possible. The TGR1040 provides both internal or external FM modulation usinge either the internally generated 1kHz modulator signal or an external signal in the range 300Hz to 50kHz. Now every engineer involved in RF design, manufacture or testing can have a generator of their own. Precision and Stability The TGR1040 uses a fully synthesised source locked to a temperature compensated crystal oscillator. This provides excellent signal frequency stability against temperature and ageing. Careful low power oscillator design has yielded good phase noise characteristics. The frequency can be set to a resolution of 1kHz across the whole frequency range, yielding a precision of 1ppm at 1GHz. Frequency steps can be set from 1kHz up to 999*999MHz. The frequency stepping system makes operations such as precise amplitude response characterisation particularly easy. Ease of use Ease of use was a major consideration in the design of the TGR1040. A simple and straightforward user interface is combined with a comprehensive remote command set. The clear 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. Overview The TGR1040 is a low cost, synthesised RF signal generator which incorporates the essential features required for most development, test and service work - frequency accuracy and stability, wide dynamic range, low phase noise and low leakage. The generator incororates both internal and external FM. It is suitable for 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. The instrument can be operated manually via the front panel or can be remotely controlled via the RS-232 interface (standard) or GPIB interface (optional). Nine memories are provided for user set-ups. In addition the generator's low cost, it's ease of use and remote control capabilities make it eminently suitable for most production and development applications where a basic, stable signal source is required. 10MHz to 1000MHz frequency range 1kHz setability at any frequency 2ppm accuracy over 5oC to 40oC -127dBm to +7dBm amplitude range Amplitude control in 0.1dB steps FM modulation, internal or external 80 character back-lit LCD display Keyboard and rotary encoder control Non-volatile storage for 9 user set-ups Full remote control via RS-232 or GPIB Outstanding price/performance ratio There is no requirement to set both a level and an attenuator setting, the internal arrangements are transparent to the user, just set the level required and switch on the output. 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. Wide amplitude range The TGR1040 provides an amplitude range of -127dBm to +7dBm (0*1V to 500mV into 50). 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 all-electronic attenuators provide highly repeatable output levels and are more reliable than mechanically switched sysyems. Careful attention to screening requirements has given low output leakage so as not to affect low level measurements in sensitive circuits such as receivers. This wide bandwidth allows for audio band demodulator testing as well as LF digital modulation. Programmability for routine testing The TGR1040 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 TGR1040 provides full remote control facilities for all its functions. An RS-232 interface is provided as standard and a GPIB (IEEE-488.2) interface is available as an option.
