Atec Aeroflex-RDL_NTS-1000B - Manual (Page 7)

The RDL Model DCR-14000A Downconverter utilizes
technology that RDL developed for military radar sys-
tems. The LOs are based on seven very low noise
sources that are based on an 80 MHz crystal oscillator.
These are mixed and matched to create 21 separate
bands, each with very low phase noise. The output con-
version gain is nominally 3 dB and the input required
is only 0 dBm. You won’t need to find a low-noise
microwave amplifier to make your signal big enough
to measure. The output is band limited to 60-700 MHz.
The basic unit covers the frequency range of 1 to 14.7
GHz. There is continuous frequency coverage, no
holes around each LO, and the phase noise levels are
state-of-the-art.
The frequency range of the DCR-14000A can be extend-
ed to 25 GHz with Option 01. The 10.24 GHz LO that is
available full time inside the DCR-1400A is made avail-
able on the rear panel for mixing from higher frequen-
cies. The phase noise performance of the DCR-14000A
at these higher frequencies is virtually the same as at
the lower bands because this LO’s noise is correlated
with the noise of the other LOs. The 10.24 GHz signal
is +10 dBm to accomodate a wide range of mixers.
The DCR-14000A can also be configured as a source.
Option 02 is available where the individual LOs of the
DCR-14000A can be output. Applications such as mea-
suring the phase noise of a block downconverter is easy.
The DCR-14000A’s LOs can be the input and the output
of the converter, usually within the frequency range of
the NTS-1000B, can be measured directly, without lock-
ing, and you will know that the noise you are measuring
is the noise of the DUT, not the noise of the source.
