The RPM3000 module is an eight-port, high-speed return path quadrature
amplitude modulation (QAM) and spectrum analyzer optimized for the QAM
and ingress analysis and monitoring functions of the PathTrak Performance
Monitoring System. Each of the eight ports is an independent and isolated test
port. The RPM3000 module switches automatically between the eight ports and
individually measures both QAM and spectrum performance on each. The measurement settings and functions of the RPM3000 consist of all typical spectrum
analyzer settings such as resolution bandwidth, video bandwidth, dwell time,
span, marker control, maximum hold, minimum hold, peak search, and zero
span. The RPM3000 provides flexibility to adjust these parameters in monitoring
plans, or provide interactive analysis according to individual preferences.
Fast Scanning—Catches the Most Transient Noise and Ingress
The RPM3000 consists of a single QAM/spectrum analyzer measurement receiver
with eight individual input ports that are switched into the receiver. The overall
measurement speed across ports is optimized through use of an integral highspeed switch, unique measurement algorithms, digital receiver technology, and
dual digital signal processing (DSP) hardware architecture. In addition, the
RPM3000 is designed with a detector for measuring very fast transient noise,
ingress, and bursty signals. The RPM3000 can reliably detect and measure bursts
of noise as short as 1 µs.
RPM3000 MODULE
Flexible Measurement Plans to
Adapt to User Preferences
Users have ultimate flexibility in
programming the RPM3000 for realtime troubleshooting and monitoring.
The measurement parameters of
individual ports can vary, which
allows the user to program each of the
eight ports on a single RPM3000 with
a different measurement plan. In
addition, within an individual port,
the measurement parameters can be
varied by frequency allowing different
spans of the return spectrum to be
scanned with different resolutions, or
certain spans of the spectrum to be
skipped altogether.
Expands and Scales with No
Degradation in Performance
As part of the PathTrak Performance
Monitoring System, the RPM3000
monitoring modules are virtual
memory extension (VME)-based
cards that mount into a modular
headend controller unit (HCU)
control chassis (HCU400 or
HCU1500). Thus, a monitoring
system can be designed to serve the
existing number of test points today,
and then can be expanded easily by
adding additional RPM3000 modules.
Furthermore, because each RPM3000
module is an independent QAM and
spectrum analyzer receiver, adding
modules to accommodate more test
points does not adversely affect the
overall system speed or performance.
