The requirement for phase noise levels in the new
PCS applications is unprecedented. The DCR-2500A
has the lowest noise available and the levels are low
enough, when combined with the NTS-1000B, to
measure these extremely low levels.
The RDL Model DCR-2500A is a unique downcon-
verter in that the LOs inside have extremely low
phase noise. There are three overlapping bands in
the DCR-2500A that provide continuous frequency
coverage between 1 GHz and 3.26 GHz. The output
frequency range is bandpass filter limited to
between 60 and 700 MHz.
This unit requires only a 0 dBm input level. RDL
puts the gain inside the DCR-2500A so that an
external low-noise amplifier is not required.
Conversion gain is a nominal +3 dB and the DCR-
2500A output is sufficient to drive the Model NTS-
1000B Phase Noise Analyzer.
The DCR-2500A operates under IEEE-488.2 exter-
nal control. The user can select a band or just send
a frequency and the DCR-2500A will automatically
select the correct band. The NTS-1000B has an
input screen, also available over the IEEE-488 bus,
that inputs the downconverter’s LO frequency. This
allows the NTS-1000B to properly interpret its
input to display the correct measured frequency.
The DCR-2500A extends the measurement speed
and convenience of the NTS-1000B into the PCS
frequency bands.
