2 INTRODUCTION
The field strength meter EP2500 provides total coverage in the Terrestrial, Cable Television (CATV)
and first IF Satellite bands.
Even though this is a technically advanced instrument, its relatively low cost makes it very popular
among a wide range of installers, from the professional who is busy with certifications for large system
installations to the electrician who has just started making himself known in the TV installation trade.
The main features of this instrument are:
• Wide dynamic range of the measurable level: from 20 to 130 dBµV in all ranges.
• Level measurement, video/audio carrier ratio for both Terrestrial and CATV bands, carrier/noise
ratio and digital channel power, both terrestrial and satellite.
• True BER measurement by means of a QPSK card (standard accessory), of a QAM card (as an
alternative to the OFDM card) or of an OFDM card (as an alternative to the QAM card). If either
card is missing, the unit shows a BER estimation (as opposed to true BER measurement) of the
missing card based on true C/N measurement.
• Viewing of free to air digital signals by means of an MPEG 2 card (standard feature).
• 4 ½ “ black and white CRT for on screen menu and measurement display (OSD), analogue TV
picture display, spectral analysis, horizontal synch pulse, measurement bars.
• Microprocessor control.
• Data Logger.
• Teletext.
• PLL frequency synthesis tuning throughout all the frequency ranges.
• 100 program storage capability.
• Spectrum analyser with variable frequency selectivity and expansion.
• AM, FM, TV intercarrier demodulation.
• Power to LNB and driving commands by means of a 13/18V 500mA source, a 22kHz switching
tone and DiSEqC

1.1 and 1.2 (for steerable dishes) switching protocol
.
• SCART socket.
• An auxiliary 11V/150mA source of power with automatic protection is available to the operator.
• RS232 port.
• USB port.
• Power and battery charge by means of an external Vac-to-Vdc power supply/charger unit (standard
accessory) or by means of an internal battery (optional) with a long operational run and located in a
fast-access compartment.
• Compact and lightweight.
