You can receive the streaming phase data on any machine that can access the server on your network,
including the server PC itself. Either
Acquire→ Symmetricom 5115A / 5120A / 5125A (Frequency
stability) or the more general Acquire→Acquire from TCP/IP streaming server option can be used to
retrieve phase data from TSERVE. In Figure 93 above, the latter has been selected. The Input Frequency
field in the acquisition dialog has been populated with the 100-kHz rounded value that would be
reported by the
show inputs command, while Sample Rate is set to the final data rate of 10 samples per
second. With an Output Decimation value of 1, no additional decimation will be performed by TimeLab.
TimeLab can receive data concurrently from multiple instruments. When the PhaseStation 53100A
measurement described above was run alongside a Symmetricom 5125A test set connected to the same
signal sources, the result shown in Figure 94 was obtained:
For this exercise, the Symmetricom 5125A’s phaserate property was left at its default value of 1000
samples per second. Consequently, its Allan deviation trace begins at t
0
=0.001 second, while the
PhaseStation measurement begins at t
0
=0.1 second. The results are otherwise virtually identical.
