SPECIFICATIONS


Input


Level


VHF/UHF/SAT from 20 to 130 dBµV (-90
÷ +20 dBm).




HF from 40 to 130 dB


µV (-70
÷ +20 dBm).


Measurement Unit


dB (for ratio measurements), dB
µV, dBmV, dBm and V.




Attenuator



(Selectable manual or automatic insertion)
HF/VHF/UHF/SAT from 0 to 60 dB in seven 10 dB steps.






Attenuator accuracy


HF/IF/VHF/UHF ± 1dB. SAT
± 1.5 dB.




Frequency response


within
±1 dB throughout the entire frequency range (automatic linearity




correction).


Reading


1. Digital with 0.1 dB level resolution.

2. Digital C/N (video carrier / noise) ratio.

3. Digital V/A (video / audio carrier) ratio.

4. Analogue, on the video display, by means of luminous bar with linear

50 dB reading scale located on the upper part of the screen.

5. Digital power (for wide band digital transmissions).

6. Acoustic; possibility of including a note whose tonality is proportional

to the level of the applied signal.


Measurement



Switchable: quasi peak or average value.
