VIDEO ANALYSIS & MEASUREMENTS (SYNCHRO & I.T.S. VIDEO LINES)
• Visualization of the synchro and burst, according to time and amplitude
• Selection and visualization of all the video lines and ITS expandible with Zoom
• S/N-W measurement
TV SPECTRUM ANALYSIS
• Frequency band: 4–878 MHz
• Span in TV band: 2–5–7–10–20–50–100– 200–500–FULL–VHF–UHF
• Span in RP band: 2–5–7–10–20–50–RP (4–65 MHz)
• dB/div: 1–2–5–10
• Dynamic range: >60 dB
• Measurement resolution: 0.1 dB
• Measurement filter bandwidth: TV 130 KHz at –3 dB
• Reference level: from 0 to 130 dBµV, from –60 dBmV to +70 dBmV
• Spectrum setting: automatic or manual, selectable
• In automatic spectrum mode: Passing from measurement (MEAS) to spectrum (SPECT) you can immediately see only the
spectrum of the program/channel received perfectly centred and automatically aligned to the reference level
• Spectrum parameters set automatically:– Ref level/power indication at the top of the display (corresponding to the attenuator in old
instruments)
– Span: 10 MHz
– dB/division: 10 dB/
• Frequency/level marker position:
– For digital signals in channel centre
– For analog signals on video carrier
• Measurement band selection & correlation of analog or digital signals: shown on display
• Other spectrum selections:
– MARKER: OFF, ON, C/N per segnali analogici (2 markers to measure BW power)
– MARKER BW: OFF, ON, BW POWER
(1+2 markers for chan. filter calibration)
– MAX HOLD: OFF, ON
– PICTURE: only contours or full
– DEFINITION: high 320 points, medium 160 points, low 80 points
– BUZZER: OFF, MRK LEVEL
• Possibility of storing 99 spectrum pictures (Data Logger)
SAT SPECTRUM ANALYSIS
• Frequency band: 930–2250 MHz
• Span: 5–10–20–50–100–200–500–FULL
• dB/div: 1–2–5
• Dynamic range: >30 dB
• Measurement resolution: 0.1 dB
• Measurement filter bandwidth: SAT 4 MHz at –3 dB, VSAT 0.2 MHz at –3 dB
• Reference level: from 0 to 126 dBµV, from –60 dBmV to +66 dBmV
• Spectrum settings: automatic or manual, selectable
• Automatic spectrum mode: Passing from measurement (MEAS) to spectrum (SPECT) you can immediately see only the spectrum
of the program/channel received perfectly and automatically aligned to the reference level
• Spectrum parameters set automatically: – Ref level/power indication at the top of the display (corresponding to the attenuator in
old instruments)
– Span: 50MHz
– dB/division: 5 dB
– Freq./level marker position: in centre band

– MARKER BW: OFF, ON, BW POWER (1+2 markers to measure the power/bandwidth)
– MAX HOLD: OFF/ON (peak memory)
– PICTURE: contours or full white
– DEFINITION: high 320 points, medium 160 points, low 80 points, selectable
– V.S.A.T (very small aperture terminal) spect.
– SAT POINTING: automatic optimum setting for satellite dish pointing
– BUZZER: OFF, MRK POWER
• Possibility of storing 99 spectrums (Data Logger)
