low noise electronics & physics for frequency & phase comparison
Distribution:

The function of a distribution amplifier is to faithfully reproduce the input at a number of outputs, 4, 6, 12, 24 or 32 and up, usually at unity gain and in a 50 Ohm system. So, a Distribution Amplifier makes it possible to have multiple outputs from a frequency standard to reference the entire quartz oscillator based instrumentation in, say a microwave development laboratory or production test facility. Spectrum Analyzers, Frequency Counters, Microwave Analyzers, Network Analyzers, Signal Sources, Digital Oscilloscopes etc. the performance of all these instruments can be significantly improved, very simply, by using say a Rubidium reference plus a distribution amplifier to provide a more accurate and stable 10MHz reference to the external reference input for each of the Instruments in use.

A5000 Distribution Amplifier


Quartzlock produce very high performance Distribution Amplifiers (A5) and also low cost (A5000) units. Only isolation and phase noise parameters have noticeably lower specifications in our A5000 instruments.

The core specifications of a Distribution Amplifier are: Isolation input to output and output to output (input to input in multi-channel amplifiers) expressed in dB. Phase Noise added to the input signal, expressed in dBc/Hz in a specific bandwidth, usually 1Hz. Distortion added to the input signal, harmonics and spurii, expressed in dBc. Phase / Temperature stability, expressed in ps/C. Short Term Stability AVAR Allan Variance, expressed in e-X /tau, i.e. 3x10-14/s (this is actually the spec of our Quartzlock A7-MX frequency and phase analyzer used to measure an A5 or A5000 @ typically e-13/s)
