TECHNICAL SPECIFICATIONS
Input characteristics
Level
VHF/UHF/SAT: from 20 to 130 dBµV (-90 to +20 dBm).
HF: from 40 to 130 dBµV (-70 to +20 dBm).
OPTICAL: from -20 to + 2 dBm (+12 dBm with attenuator)
Units of measure
RF: dBµV, dBmV, dBm and V, dB (for ratio measurements).
OPTICAL: dBm.
Attenuator
(With selectable manual or automatic insertion).
HF/VHF/UHF/SAT from 0 to 60 dB in seven increments of 10
dB each.
Attenuator accuracy
HF/ VHF/UHF ± 1dB, SAT ± 1.5 dB.
Frequency response
within ±1 dB throughout the entire frequency range
(automatic linearity correction).
Reading
1)
Digital level with a resolution of 0.1 dB.
2)
Digital C/N ratio (video carrier / noise).
3)
Digital V/A ratio (video / audio).
4)
Analogue level by means of a luminous bar with a linear 40
dB reading scale, located on the upper portion of the
screen.
5)
Digital power (for high-bandwidth digital transmissions).
6)
Acoustic; possibility of including an acoustic note, with a
tone proportional to the level of the input signal.
Measurement
Switchable to near peak or average value.
Measurement
bandwidth (at -3 dB)
HF/ VHF/UHF 100 kHz - 1 MHz (selectable).
SAT 100 kHz - 1 MHz - 4 MHz (selectable).
Input impedance
Dissymmetrical at 75
Ω
(50
Ω
upon request),
with DC component blocker.
Maximum applicable
voltage
100 Vdc (with "LNB" voltage excluded) and/or 5 Vpp RF.
Input connector
RF: BNC (supplied BNC/IEC and BNC/F external adapters).
OPTICAL: FC/APC
(optional SC/APC and FC/PC external adapters)
"LNB" Power Supply
Input connector output in two selectable modes:
•
steps of :0 – 5 – 13 – 15 –18 –24 V.
•
continuous: from 5 to 23.8 V with a resolution of 0.2 V.
500 mA maximum current. Output current monitor with a
resolution of 20mA, indication of ohmic continuity for the
external circuit and overload.
Optical LNB power supply (13 V)
22KHz Tone
(Input connector output) Frequency: 22 kHz ± 0.5kHz –
Amplitude : 0.6 Vpp - Waveform: rectangular.
