External lock aids signal generator
stability
TTi has added an external frequency locking capability to enhance the frequency stability of the TGR2050 low-cost full-performance 2GHz signal generator.
TTi (Thurlby Thandar Instruments) has added an external frequency locking capability to enhance the frequency stability of the TGR2050 low-cost full-performance 2GHz signal generator The generator uses a fully synthesised source locked to a temperature-compensated crystal oscillator, providing frequency stability of better than 1ppm over a 15 to 30C temperature range and an ageing rate better than 1ppm per year

Budget pricing for fully featured 2GHz generator
The TGR2050 is a low-cost synthesised 150kHz to 2GHz signal generator which incorporates the essential features required for most RF development, test and service work.
Compact bench power supply provides 175W
The EX355, new from TTi (Thurlby Thandar Instruments), is a single-output laboratory DC power supply providing an output from 0 to 35V at 0 to 5A.
Programmable power-supplies offer outputs to 1kW
The XHR range of programmable power supplies, offering output ratings up to 1 kW is power-factor corrected for low current draw and reduced generation of input current harmonics.
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 setting capability of 0.005ppm.
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 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 generator provides an amplitude range of -127 to +7dBm (0.1uV to 500mV into 50ohm).
Setting resolution is 0.1dBm or 0.01uV.
Output level steps can be set anywhere between 0.1 and 100dBm (or 0.01uV to 100mV, depending on the entry mode).
Stepping the level is useful in applications such as quick assessment of 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 for accurate low-level measurements in sensitive circuits such as receivers.
Full remote-control facilities are provided for all the instrument's functions via both RS232 and GPIB (IEEE488.2) interfaces.
In addition, it can store nine full instrument setups in nonvolatile memory.
This allows repetitive testing procedures to be undertaken quickly and accurately.
The TGR2050 incorporates a 4 x 80-character backlit display, numeric entry keypad and rotary encoder.
The compact casing measures 130 x 212 x 330mm (half-rack width by 3U height), and the weight is 4.6kg.
The price in the UK is GBP 2195 (plus VAT).
