PreEqualization Analyzer: Features
DOCSIS PNM Data
PreEqualization Analyzer is a Proactive Network Maintenance (PNM) tool that lets you clearly see which devices are being impacted by upstream impairments like micro-reflections and group delay, the severity of the problem, and the approximate location of the fault that’s causing the issue. And, you can see the issue before service is ever impacted for the subscriber. That lets you proactively fix the problem as part of your routine.

Interactive Mapping: Detailed View
Strand Map Overlay
When viewing a device in a table or on the map you can drill-in to see more details such as the modem vendor, software version, MAC Address, port, digital tap response, in-channel frequency response, micro reflection levels, group delay, TDR, and VTDR. You can also see if the modem is associated with a correlation group, which is when the application identifies a common impairment affecting multiple modems (see below). In addition, you can view the history of the modem to see past performance.
PreEqualization Analyzer automatically identifies groups of modems that are likely being impacted by the same upstream impairment. The devices are clearly identified on the map, allowing you to see which subscribers are impacted and which nearby devices are not part of the identified group. The application also calculates a vTDR distance, which is the length of the micro-reflection. This information provides you the data you need to more easily find the source of the problem. You can also view past correlation groups with our correlation history feature to see any changes that have occurred over time.
Full Band Capture Spectrum Analysis
SpectraVizion – included in your PreEqualization Analyzer license – displays a list of devices experiencing downstream spectrum issues. You can drill-in to view a capture of the full spectrum from that day for any device that supports spectrum capture. Click again to see captures from previous days. You can also rescan the modem at any time to capture the current spectrum and see if anything has changed.
Upstream Spectrum Analysis
Our Upstream Analyzer—a separately licensed module available in the same interface—displays the upstream spectrum from your CMTS in real time from anywhere. You can view the live spectrum passing through the CMTS on a PC or mobile device. There are settings for Max Hold and Min Hold, and with one click you can view ingress under the cable modem. You can also view a history of the upstream spectrum over time. Best of all, there’s no expensive equipment or complicated cabling to set-up. All you need is your CMTS.
Cable Modem Installer and Birth Certificates
With our Cable Modem Installer and Birth Certificate feature, your installer can make sure the cable modem meets your criteria before leaving the subscriber’s home—and you have a permanent history of that install. When your technician runs the Cable Modem Installer it automatically checks key upstream, downstream and PNM readings. The test clearly shows where a device passes or fails so that any issues can be addressed by the technician before they leave the home; or, if need be, handed off to another technician if the problem is further out in the plant. That definitely beats having to roll a truck a week later to a newly dissatisfied customer.
The Cable Modem Installer can be run multiple times from any location. Each time it is run it generates a Birth Certificate, which includes the last test results and readings, the tech’s name and a timestamp. This provides you with a record of each installation attempt, allowing you to track overall installation success. This also keeps your installers accountable, including any contractors you may employ, and it can show you where there may be a need for additional training.
Integrated Work Orders
If you see an outage or an opportunity to do some proactive maintenance, you can send a work order to the nearest available technician, which is pushed to their mobile device. Through the app they can log all work performed – making notes, adding pictures if needed, and closing it out. You can check the status of the work order at any time so you have up-to-the-minute information on what has been completed and which technicians are available.
PNM Mobile App
The Nimble PNM Mobile app was created specifically to sync with the PreEqualization Analyzer desktop application. Download and install the app on your mobile device and get fast and easy access to PreEqualization Analyzer from the field. You can manage your proactive network maintenance activities directly from the app anywhere and anytime. At the touch of the screen, you’ll have access to key PreEqualization Analyzer features including device screens, correlation groups, Cable Modem Installer, Work Orders, SpectraVizion downstream spectrum capture, and Upstream Analyzer (licensed separately). Nimble PNM is available for both Android and iOS devices on Google Play and the App Store.
