Phase Noise Test Set Overview:
Wenzel Associates BLUE PHASE 1000TM series test set
integrates B LUE T OPSTM modules and other ultra low noise
components into a manually operated or computer
controlled phase noise measurement system. The B LUE
PHASE 1000TM test set is modularly constructed, allowing
complete flexibility for use in multiple configurations and
achieving extremely low noise floors.
The Residual Phase Noise Test Set (BP-1000-RM) consists of
a two chassis configuration. The BPMS-1000-RM is the
Residual Phase Noise Measurement System, which is housed
in a 5¼” high rack mountable chassis. This unit is powered
by the BPPS-1000 Low Noise Power Supply, which is housed
in a 5¼” high half-rack or full-rack chassis. The BPMS-1000RM phase noise measurement system is configured to
facilitate the accurate residual (additive) phase noise
measurements of active or passive two-port devices such as
amplifiers, multipliers, dividers, splitters, cables and filters as
well as mixers.
The residual phase noise measurement requires only one
frequency source. The signal from this frequency source is
first reactively power split. One output of the splitter passes
through the device under test (DUT), while the other output
passes through a phase shifter. Two DUT’s are required for
devices that change the frequency (ie. multipliers, dividers,
etc.) The phase shifter is adjusted to put these two signals
in quadrature at the input to a mixer. The phase noise from
the frequency source is coherent at the inputs to the mixer,
and therefore, mostly cancelled. The remaining phase noise
present at the mixer output is the residual noise from the
DUT1 (and DUT2 if present). The measured voltage
variations at the mixer output are easily converted to phase
noise by correcting for mixer conversion and amplifier gain.
