USER'S MANUAL. PROMAX-10
Ratio between carrier level and the channel's noise
level.
Ratio between the channel power and the noise
level. The frequency where noise is measured is
user definable in absolute or relative value. In the
relative mode, the unit takes as default frequency
offset the value BW/2 + 0.5 MHz.
40-50 dB for input level between 60 and 70 dBµV.
> 50 dB for input level > 70 dBµV.
> 30 dB for input level > 60 dBµV.
± 2 dB (45 – 862 MHz) ± 3 dB (5 – 45 MHz)
Ratio of the peak level of the video carrier to the
peak of the distortion products of second order
beat. Measured at four frequencies user definable.
User definable from -2.50 to -0.50 MHz and from
0.50 to 2.50 MHz. (Default values -1.50, -0.50, 0.50
and 1.50 MHz).
Ratio of the peak level of the video carrier to the
peak of the distortion products of third order beat.
Measured at the carrier frequency or, approximately
mode, in a channel previously defined by the user.

Channel power and MER. (BER for data dumping to
printer or transfer to PC).
Variable: 10, 30, 100, 300 MHz and full band (from
5 to 862 MHz, according to the channel plan).
Forward band (45 to 862 MHz).
Variable from 60 to 120 dBµV in 10 dB steps.
Numerical and by level bar.
Forward (45 to 862 MHz) or Return path (5 to 100
MHz).
4 per band.
From 5 to 862 MHz.
