GNSS Positioning Simulator: Can I use DACS0 to turn off a channel on an STR47xx?
Environment/Versions
STR4730 / 4750 / 4760 / 4780 / 4790
Answer
To turn off channels during a calibration use command = CAL0 (see
FAQ13846
).
DACS is a command used during the power calibration procedure (see
DCS0002C
section 3.5).
It is not recommeded for customer use at any other time.
DACS0 does not turn a channel off. It just sets the signal level to 'off'
The channel is still running
You will see this on the simulator LCD screen
Never send the DACS0 command after you’ve finished setting the wanted target power or after you’ve run the DACT utility.
This will invalidate the power calibration
DACS0 will program the simulator channel to always have an 'off' signal level
