3. OVERVIEW
ST-5810 supports digital TV analysis and measurement of all broadcast TV standards – DVB-S/S2, DVB-T/T2, ISDB-T/C/S, DVB-
C/C2, J.83A/B, and ATSC 1/0/3.0 over Satellite TV, Terrestrial TV, Cable TV and Over-the-Air Broadcasting TV in full frequency
range.
Before using the tester, dedicated digital TV standard needs to be selected by dropping down the selection box form the
top of the display screen as shown below. Depending on the regional requirement, your tester may not be configured to list
all digital TV standards for selection. Contact your local sales channel for optional standards to be enabled in case required
settings are missing.
3.1 KEY FFEATURES
Level Measurement
When tuned to a single channel, the ST-5810 displays bar graphs for the video and audio carriers or power of a digital
channel. It also shows numeric readouts of the carrier amplitudes and V/A difference or digital power.
QAM Measurement
The ST-5810 is capable of measuring the channel power of QAM, QPSK, and COFDM signals. This function also enables the
measurement of pre- and post-BER and MER for QAM modulated signals. The QAM measurement mode also features a single
channel spectrum display and an optional Constellation diagram is available to enable users to find errors more quickly.
BER Measurement
The BER Measurement function displays the ratio of corrupted bits to total bits in the QAM signal. The analyzer dwells on the
selected channel, counting good bits and watching for individual corrupted bits. The BER graph shows errored bits as vertical
lines that expand horizontally across the display with advancing time.
Tilt Measurement
The Tilt Measurement function displays a graph showing the amplitudes of up to twelve user- selected video carriers. This display
also shows the calculated difference in amplitude (tilt) between the highest and lowest channels in the user-selected group. The
ST-5810 can also display a numeric list that shows the amplitudes of the carriers in the group.
Multi-Channel Scan
The Channel Scan Measurement function displays the full span of video and audio carriers in the selected user channel plan. This
mode is useful to make a quick check of your system's overall flatness and amplitude.
Amplitude limits can be imposed on the display and the frequency marker can be used to isolate any suspect channel that
appears in the display.
