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.
In addition, the generator's low cost, ease of use and remote control make it eminently suitable for most production and development applications where a basic stable signal source is required.
The TGR1040GP uses a fully synthesised source locked to a temperature-compensated crystal oscillator.
This provides excellent signal frequency stability against temperature and ageing.
The frequency can be set to a resolution of 1kHz across the whole frequency range from 10MHz to 1GHz, yielding a precision of 1ppm at 1GHz.
Stability is +/-2ppm over the temperature range from 5 to 40C.
The instrument provides an amplitude range of -l27 to +7dBm (0.l uV to 500mV into 50ohm).
Setting resolution is 0.l dBm or 0.0luV.
Output level steps can be set anywhere between 0.l and l00 dBm (or 0.0luV to l00mV depending on the entry mode).
Stepping the level is useful for quick assessment of parameters such as circuit linearity and dynamic range.
The generator provides internal or external FM modulation using either the internally generated 1kHz modulator signal or an external signal range in the range from 300Hz to 50kHz.
This wide bandwidth allows for audio demodulator testing as well as low-frequency digital modulation.
The TGR1040GP provides full remote-control facilities for all its functions.
In addition, it can store nine full instrument setups in nonvolatile memory.
This allows repetitive testing procedures to be undertaken quickly and accurately.
The TGR1040GP costs ?1399 (plus VAT) in the UK.
