 Comprehensive Accurate and Affordable
The MSI-4400A is the most comprehensive 8vsb monitor on the market today. A single screen provides at-a-glance information on the most important parameters of the 8vsb signal.
Hardware
The MSI-4400A Analyzer includes a single rack unit controller that receives and evaluates the 8vsb signal and relays the data to a Windows based PC. The front panel indicators show the status of alarms and confirm RF level and signal strength. External connections for Alarms, LVDS, SMPTE 310M and DVB-ASI are all accessible from the rear panel.
 Software
The MSI-4400A Analyzer’s software runs on a dedicated Windows-based computer. The software provides a complete display that shows all the critical 8vsb parameters, in a clear easy to understand format.
8vsb Analyzer Page
This is the home screen of the MSI-4400A’s software controls. It offers a comprehensive overview of the 8vsb signal. Key displays including Eye Pattern, SNR/MER/EVM, Constellation, Signal Quality Meter, Alarm Status, Bit Error Rate Display, Packet Error Display and Symbol Rate Deviation data, are all viewable from the home screen.
Eye Patter & Constellation Displays
The Eye Pattern Diagram and the Constellation Display are available as individual windows, and are user-configurable. Both offer a Rolling mode, which is an average over time; or Refresh mode where data is permitted to accumulate for a period of time, is cleared and re-accumulated.
Alarms & Alarm Logging
Extensive alarm capability permits user set-up of upper and lower alarm limits as well as notification intervals in case of an alarm. All alarms can be set to trigger e-mail notification. The unique Alarm Log stores all readings for the 2 minutes prior to and after an alarm occurrence. return to top
Data Trend File
The Trend File maintains a rolling year of data. Trends are captured at hourly intervals, and stored for immediate or future analysis. The data is exportable to other spreadsheet files, such as Excel, at the click of a button, permitting extensive data analysis capabilities. Parameters logged include: signal quality, Lock, RF status, SNR, MER, EVM, Pre/PostRS BER, packet error, symbol rate deviation, and Spread. return to top
Equalizer Tap Energy
The most powerful analytical page of the MSI-4400A allows extensive examination, analysis and manipulation of the equalizer parameters.
Zero the equalizer taps to measure transmitter performance, capture data to memory for graphic comparison of live readings, freeze the FFE or DFE independently or simultaneously expand the display in the Delay and Amplitude Axis. Graticule lines permit accurate numerical readout of individual tap amplitude and delay.
Two easy-to-read windows display the user selected Tap Number, its energy and its weight

 Strip Chart SNR/MER/EVM
Virtual strip chart recorder displays 20 minutes of signal quality data; Choose from SNR/MER/EVM. The MSI-4400A’s SNR measurement meets ATSC recommended performance of at least 27 dB S/N and provides sufficient capability for measuring transmitters that exceed ATSC specifications with the equalizers OFF
With Equalizers OFF, the MSI-4400A reflects the true margin that consumer receivers will be able to utilize to correct the received signal return to top
Fully Web Enabled
A true web appliance, the MSI-4400A offers full internet compatibility. Inherent high security provides protection from hacking, while set-up options permit “control” and read-only functions. A user can access the MSI-4400A from any location and analyze the 8vsb signal. return to top
Packet Errors
This feature displays packet Errors per second. return to top
Symbol Rate Deviation (ppm)
Provides the deviation from ideal ATSC symbol clock frequency in parts per million. return to top
User Controlled Line
A user-configurable hardware line can be controlled from the home page. return to top
Adjacent Channel Rejection Filters
Designed for use with either the Tap Weight Equalizers OFF or ON, depending on your measurement needs.
