Purpose of the development: Digital signal analyzer LFM-5000 is used to set the reception of digital terrestrial systems (air) television (DVB-T), digital cable (DVB-C) and digital satellite (DVB-S). For signals with analog modulation allows to measure the signal strength of the images in the selective microvoltmeter in spectrum analyzer mode, measure signal strength in a selected frequency band, the signal / noise ratio. Allows you to build a histogram of a specified channel.

Recommended application field: Telecommunications services and equipment - organizations, research, and services.

Technical characteristic: Input / output connectors N (m), 50 VSWR, not more than 1.6 Supply voltage 200 ... 250 V The power consumed by the network <= 20W Time of battery life, at least 2 h Battery charge time is not more than 12 hh Warm-up time 5 min Time to failure, at least 10,000 hh Average service life of at least 5 year Information display Monochrone LCD 10 cm (3,7 ") 320 (H) x 240 (V) LED TV (to view the video) Colour, 4 "TFT, 480 (H) x 234 (V) Dimensions 100x240x250 mm Weight 3 kg

Advantages over analogues: In addition, the meter allows you to: - Save in non-volatile memory up to 50 bar graphs and spectrograms, with subsequent transfer to a computer via an RS-232; - To form the power supply to the antenna preamplifier (DVB-T and DVB-C); - To form voltage LNB: +13 / +18 V (400 mA), 22 kHz (DVB-S); - Support instruction DiSEqC (layer specification 2.1)

The development stage readiness: Introduced in production

Description of the development:
()
For signals with digital modulation types METER allows: - Measurement of the power level of the digital channel - Measurement of the digital channel power ratio to the noise in the channel (SNR); - Measurement of bit error rate to a Viterbi decoder (CBER); - Measurement of BER after Viterbi (VBER); - Measurement of the modulation error rate (MER); - Building a constellation diagram; - Measurement of the difference between successive PCR packets. To control the quality of available TV channels METER can discover and browse channels with digital modulation types for built-in color TFT display (sound - the built-in speakers), the audio / video signals to external connectors, and use the built-in TFT display as a monitor, giving the external signals Audio / Video. The measuring unit consists of a common core and a set of options (Signal Level Meter TV range, the spectrum analyzer satellite (950-2150 MHz) and MMDS (2380-2700 MHz) bands analyzer DVB-T, DVB-C analyzer, analyzer DVB-S), which on request can be completed METER
