Noise Density
Abracon’s ABPSM-ULN-A
solution provides an Ultralow
noise power supply source (25 nV / √Hz @ 1kHz), with
four regulated DC Outputs.
Offering 1.8V, 2.5V, 3.3V and 5.0V DC bias ports;
this module is uniquely positioned to replace
multiple, low noise, linear power supplies which
are typically needed to bias noise sensitive circuitry.
ABPSM-ULN-A
is designed to utilize a Universal low
Noise AC Adapter, enabling
World-Wide functionality,
accepting 100VAC~240VAC; 50Hz and 60Hz cycles.
Coupled with state of the art low noise regulation,
this Power Supply Module (PSM) provides an optimal
setup to conduct noise sensitive measurements of
System Critical circuitry, such as phase noise, jitter,
spectral purity and S/N (Signal to Noise ratio).
