The SensarPro is a 10db amp. The gain setting can be set from 0 to 20. 20 equates to 10db and 0 cuts off the signal completely. I am assuming that the scale is linear but who knows? I chose to set it to 1 (0.5db) for readings of the amplified antennas because that's the lowest that would pass a signal. The SensarPro works well for either the batwing or Jack.---SNIP---
What do you mean "cuts it off"? As in nothing through the device at all? Seems to me that 0db is unity gain on the amp. I assume this is nothing more than a variable gain line amp, ya?
My guess is that the Sensor Pro is likely nothing but a generic TV front end/ tuner. They make those chipsets by the millions. So for critical testing I'll still trust my $60k instrument. I don't think I have an easy way to generate an accurate DTV carrier, because it would be fun to run the SensarPro through the mill and see how well it tracks it's user settings.
Setting the Sensar Pro to 0 gain completely turns off the 12V power to the antenna and has the same effect that pushing the power button on the 12V power supply has. No power, no signal. Setting it to 1 is also bad unless you are sitting very, very close to those TV towers.
