7.0 MASKING GENERATOR INPUTS
7.1 Meter – There are four bar graph meters that illustrates the level of the output signal of the generator, it is
POST the channels gain control and PRE input filters.
7.2 Masking – When the Masking window a small window will open. This window also to the selection of the
filter either White or Pink noise.
7.3 Ramp Time - The Power Ramp button allows you set the desired turn on signal ramp time during power
up. The Time buttons allows you to adjust the amount of preset time you need. The amount of steps is a
formula of gain divided by time. The ramp interval voltage change will occur every 6 seconds. The amount
of dB steps will vary depending on the total ramp time you select and the amount of gain from change from
-40dB. Example: If you choose 2 minute of ramp time and the channels gain is set for -10dB, use the following
is the formula to calculate dB rate of change (Gain = -40dB minus -10dB = -30dB) and (Time = 120 seconds / 6
seconds = 20 steps) Gain Steps = 30dB / 20 steps = 1.5 dB change per second.
7.4 Ramp Bypass - If the Power UP Ramp button is Green the ramp feature is engaged, if grey the feature is
bypassed.
