• Measures transient noise as short as 1 microsceond
• Optimized monitoring plans for specific reverse
services applications
• Real-time fast spectrum trouble-shooting without
interrupting monitoring

– Selectable dwell time
• In-service C/N measurements on TDMA cable
modem signals
The RPM2000 module is an eight port, high-speed return path spectrum analyzer,
which is optimized for the noise 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 RPM2000 module switches automatically
between the eight ports and measures spectrum performance on each port
individually.
The measurement settings and functions of the RPM2000 consist of all of the
typical spectrum analyzer settings, such as resolution bandwidth, video
bandwidth, dwell time, span, marker control, max hold, min hold, peak search,
and zero span. The RPM2000 provides flexibility in order to adjust these
parameters in monitoring plans or interactive analysis according to individual
preferences.
Fast Scanning–Catches the Most Transient Noise and Ingress
The RPM2000 consists of a single spectrum analyzer measurement receiver with
eight individual input ports that are switched into the receiver.
The overall measurement speed across the ports is optimized through the use of
an integral high-speed switch, unique measurement algorithms, fast tuning DDS
technology, and a new DSP hardware architecture.
In Monitoring mode, the measurement speed at a resolution of 300 kHz,
monitoring all eight ports, reaches ten times per second for each port – that’s an
equivalent rate of 80 scans per second. The speed is even faster if some of the ports
are deactivated or if less than 150 frequency points per port are measured.
In addition, the RPM2000 is designed with a fast detector for measuring very fast
transient noise, ingress, and bursty signals. The RPM2000 can reliably detect and
measure bursts of noise as short as one microsecond in duration.

Flexible Measurement Plans to
Adapt to User Preferences
Users have ultimate flexibility in
programming the RPM2000 for realtime troubleshooting and monitoring.
Measurement parameters can be
varied for each individual port,
allowing the user to program each of
the eight ports on a single RPM2000
with different measurement plans. 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 return spectrum
to be skipped altogether.
Expands and Scales with No
Degradation in Performance
As part of the PathTrak Performance
Monitoring System, the RPM2000
monitoring modules are VME-based
cards that mount into a modular
HCU control chassis (HCU400 or
HCU1500). Thus, a monitoring
system can be designed to serve the
existing number of test points today
and can then be expanded easily by
adding additional RPM2000 modules.
Furthermore, because each RPM2000
module is an independent spectrum
analyzer receiver, adding modules to
accommodate more test points does
not adversely affect the overall system
speed or performance.
