ANALOGUE SAT
• Frequency Band: 930–2250 MHz
• Direct selection of: memory plan, programme, frequency, LNB, DiSEqC, with front panel key
board
• Memorizaton of: plan, programme, transponder, frequency, LNB, DiSEqC, local oscillator
frequency
• Frequency resolution: 0,1 MHz
• Input impedance: 75 ohm
• Interchangeable input connector: “F” (“IEC” or “BNC” or “N” optional)
• Power Supply at RF input: OFF, +13, +18 V, 22 kHz (0,3 A) (with ON/OFF key)
• DiSEqC 1,1: 4, 8, 12 or 16 polarizations, DiSEqC “a.b.c.d” already pre-programmed in sequence
and very easy to use. IT can power any type of LNB (analogue or DiSEqC, single or dual feed)
and any type of multiswitch (analogue or DiSEqC con 4, 8, 12, 16 inputs and SCR LNB)
• Analogue level measurement dynamic range at the RF input: from 35 to 120 dBuV, from –25
to + 60 dBmV (selectable) with limit indications: level Too Low, level Too High
• Measurement resolution: 0,1 dB
• Level measurement accuracy: 1.5 dB typ. (2.5 dB max.) with software correction (after 5 minu-
tes warm-up)
• Measurement fi lter bandwidth in SAT mode: 4 MHz at –3 dB
• Measurement stability versus temperature between –10 and 50°C: 0,1 dB/°C
• LNB L.O. frequency selection: continuous from 0 to 20.000 MHz, for “L” bands (direct IF–SAT
reading), “S”, “C”, “KU”, “KA”.
QPSK (Demodulated)
• Frequency band: 930–2250 MHz
• Direct selection of: memory plan, programme, frequency, LNB, DiSEqC, with front panel key-
board
• Memorization of: plan, programme, transponder, frequency, LNB, DiSEqC, local oscillator fre-
quency, standard, symbol rate
• Frequency resolution: 0,1 MHz
• Input impedance: 75 ohm
• Interchangeable input connector: “F” (“IEC” or “BNC” or “N” optional)
• Power Supply at RF input: OFF, +13, +18 V, 22 kHz (0,3 A) (with ON/OFF key)
• DiSEqC 1,1: 4, 8, 12 or 16 polarizations, DiSEqC “a.b.c.d” already pre-programmed in seuqence
and very easy to use. It can power any type of LNB (analog or DiSEqC, single or dual feed) and
any type of multiswitch (analogue or DiSEqC with 4, 8, 12, 16 inputs and SCR LNB)
• Digital power measurement dynamic range at RF input: from 35 to 120 typ. dBuV, from –30 to
+ 60 dBmV (seelctable) with limit indications: level Too Low, level Too High

• Power Measurement accuracy: 1,5 dB typ. (2.5 dB max.) with software correction (after 5 mi-
nutes warm up)
• Noise Margin Measurement accuracy: 0,5 dB typ. (1 dB max) with software correction
• Measurement fi lter bandwidth in SAT mode: 4 MHz at –3 dB
• Measurement stability versus temperature between –10 and 50°C: 0,1 dB/°C
