Budget price for general-purpose spectrum analyser
The GW Instek GSP-827 general-purpose spectrum analyser is available from Aspen Electronics.
The C4700 is an ultra high stability double oven controlled crystal oscillator (DOCXO) with a reduced profile of just 17mm, making it the lowest profile DOCXO on the market.
The SC cut crystal provides a frequency range from 4 to 15MHz and standard frequencies of 5, 10 and 15MHz.
This ultra-stable device is specifically targeted at the stringent frequency stability requirements needed for CDMA2000 and UTMS basestations and related test and measurement equipment.
Temperature operating range is 0 to 70C and temperature stabilities are down to 0.2parts per billion.
For more general purpose base stations, synthesizers, test equipment and digital switching applications, Vectron's C4550 oven controlled crystal oscillator (OCXO) is now available in a lower cost, more compact 25 x 25mm package.
Fitted with an LPP TO-8 crystal, this high-stability device delivers better aging and g-sensitivity characteristics and improved temperature test performance.
The available frequency range of the C4550 is 5 to 100MHz.
The range is offered in either AT or optionally SC cut crystal types.
Standard frequencies are: 10, 12.8, 13, 16.384, 20, 32.768 and 100MHz.
Temperature stabilities are down to 5 parts per billion across the temperature range from -40 to 85C.
