Return values:
<Block>
<Rx Time of Week>,<Satellite ID that corresponds to the
record>,<Zero Order Doppler Term>,<1st order Doppler
Term>,<Uncertainty Doppler>,<Code Phase (or half-Chip index at
epoch Time of Transmission (GPS Sat Time))>,<Integer Code
Phase (or ms unit index at epoch Time of Transmission (GPS Sat
Time))>,<Corresponding Bit number (modulo 4) at epoch Time of
Transmission (GPS Sat Time)>,<Correlator Code phase Search
Radius>,<Azimuth Angle of the Satellite in ENU orthonormal coordinate System centered at reference point>,<Elevation Angle of
the Satellite in ENU orthonormal coordinate System centered at

The returned value is exactly one row of the acquisition assistance
data file (2G, 3G) that can be generated by the command ​[:​
SOURce<hw>]:​BB:​GPS:​ADGeneration:​ACQuisition:​
CREate​
Example:
BB:GPS:ADG:TIME 1500
sets the time of assistance data.
BB:GPS:ADG:ACQ:BLOC? 2,0.1
queries the acquisition data for SV ID 2 and time offset of 0.1s, i.e.
at GPS Time 1500 + 0.1 s.

[:SOURce<hw>]:BB:GPS:ADGeneration:ACQuisition:CREate <Create>
Stores the current assistance data settings into the selected acquisition file. The directory
is set using command MMEM:CDIRectory. A path can also be specified, in which case
the files in the specified directory are read. Only the file name has to be entered. Assistance data settings are stored as acquisition file with the specific file extensions
*.rs_acq.
Parameters:
<Create>
string
Example:
MMEM:CDIR 'D:\acq_files'
sets the default directory to D:\acq_files
SOUR:BB:GPS:ADG:TIME 1500
BB:GPS:ADG:ACQ:CRE 'acquisition'
stores the current settings into file 'acquisition'
SOUR:BB:GPS:ADG:ACQ:BLOC? 2,0.1
