Applications
Measuring Crystal
Oscillator Phase Noise
Multiplying increases the phase
noise by 6 dB for every doubling.
Multiplying by x16 would increase
the phase noise by 24 dB and
increase (improve) the apparent
noise floor of the NTS/DCR to –129
dBc at 1 kHz offset and
–154 dBc at 10 kHz offset.
Measuring Signals
Above 14 GHz
Option 01 provides a very
low noise source for mixing
down from higher frequen-
cies. The user can mix down
signals as high as 25 GHz
to within the range of the
DCR-14000A using this
option.
Measuring Additive
Phase Noise
The DCR-14000A with Option
02 can be a microwave source
that has extremely low phase
noise. In “Source” mode the
internal LOs are made available
to drive a microwave downcon-
verter or microwave amplifier
so that the phase noise of the
output can be measured direct-
ly by the NTS-1000B or another
DCR-14000A/ NTS-1000B.
