NTS -1000B

Phase Noise

Analyzer

Proven Measurement Technique

The NTS-1000B Phase Noise Analyzer uses
the proven “delay-line discriminator” mea­surement technique to accurately measure
Phase Noise at offsets between 10 Hz and 1
MHz. The NTS-1000B performs a precise cali­bration at the measured frequency before
every measurement to insure measurement
accuracy.

Self Contained

The RDL Model NTS-1000B Phase Noise
Analyzer is a unique instrument that, for
the first time, allows phase noise testing of
every part. An FFT digital signal processor
and vibration-hardened delay line are con­tained inside the unit. No external signal
generator or outside computer are
required.

Easy To Use

Measurements are made by simply push­ing the “start measurement” button or
sending an IEEE bus command. No spe-

cial training or skills are required to
operate the RDL Model NTS-1000B.
Phase locking is not required. Automatic
“pass/fail” analysis of phase noise levels
and spurious levels is provided. These
levels are user defined and the results
can be reported over the IEEE-488 bus.

Fast Measurements

The “measurement range” and “number of
FFT averages” are selectable by the user to
optimize measurement time. The NTS­1000B only measures in the selected range

to minimize the measurement time. In

production applications, where extreme-

ly fast measurements are needed, the

NTS-1000B can measure and report

the results in less than 2 seconds.

Typical measurement time for a

full range measurement, 10 Hz to

1 MHz, with 100 FFT averages,

is only 30 seconds, including an

automatic calibration.

NTS–1000B and DCR–14000A-03

The latest microwave synthesizers and the YIG
and DRO oscillators used in these sub-systems
now have phase noise levels that are lower
than even the most sophisticated military
requirements of the past. The new "Low Noise
Option" for the DCR-14000A, the –03 Option,
lowers the noise floor levels of the RDL Phase
Noise Analyzer System to easily measure to
these new levels. The fact that "phase locking"
is not required and the "10 second measure­ment speed" makes this measurement routine.
Getting near instantaneous test results allows
in-process adjustment to obtain optimum
phase noise performance. These devices can
now be subject to SPC and variations in the
manufacturing process can be monitored, on
line, and corrected before shipments are
impacted. The table shows the phase noise
performance of the DCR-14000A-03.
