Meir indicates the ratio of average total signal power in the ideal constellation to average error power in the constellation as received by the DMA120 series. Service impairment will typically be observed at bit error rates greater than here is a link to our test equipment store.

The adjacent channel levels display compares the test channel average power to the average power in each of the two higher and two lower adjacent channels. Accuracy 64qam to 4. The DMA120 series measurement screen see figure 1 shows Meir vs.

Ice RF field immunity. Although bit error rate Ber has been widely addressed as an important digital transmission figure of merit measurement, Meir provides a much earlier indication of transmission impairments. Digital transmission is new to most cable TV system technicians and so are measurements to verify performance. Quantification of digital transmission performance at any point in your system will greatly enhance technical management and decision making.

Ice eds immunity. Physical characteristics height 32 cm the DMA120 series provides the intelligence cable TV technicians need to efficiently install and maintain HF distribution plant using 64 or 256QAM transmission maximum 100% db v 40 DBMS. The signal level measurement screen plots signal levels vs. Essentially, simulated Gaussian noise is added to the input signal until a critical pre DEC Ber of is measured.

However, the calculation of error is different and is expressed as a percentage of the maximum voltage in the constellation at sampling times as received by the DMA120 series. The DMA120 series helps technicians to continue working by providing measurement pass fail indicators. Estimated noise margin indicates the headroom for digital channels and results are reported in db, similar to legacy analog measurements. This measurement may be used to check flatness across five channels or verify spectral purity of a qam modulator.

Measurement specific set up parameters are part of the individual measurement screens the display includes a bar graph which compares the values of the different taps against a dB template. Many countries impose their own customs, duties, tariffs, taxes, etc. 8 db, referenced to 25 c reference units selectable db v, DBMS, DBMS, DP pass fail indication user adjustable threshold channel power to noise channel bandwidth 6 mhz maximum ratio 40 db accuracy the typical system operating goal is to achieve a Ber of to get a real time shipping quote to your destination, enter your country and zip postal code information into the shipping calculator and get rate. Bars approaching or exceeding the template value indicate that there is noticeable system impairment detected at the test point.

Most measurement functions are no more than two menus deep. The DMA120 provides analysis of IT t j.

On items being shipped from a foreign country. Status indicators also help clarify measurement conditions the DMA120 series notes if its locking to the incoming qam signal and also if its locking to the rs decoder output.

The measurement results screen includes a bar graph comparing the test channel and adjacent channels power.
