Satellite Navigation
Copy to,SV-ID
Applies the pseudorange errors of the current satellite to selected or to all SV-IDs.
Remote command:
[:SOURce<hw>]:BB:GNSS:SVID<ch>:GPS:PRERrors:COPY:SVID
[:SOURce<hw>]:BB:GNSS:SVID<ch>:GPS:PRERrors:COPY:EXECute
on page 296
(etc. for the other GNSS systems)
Value
Sets a constant pseudorange error value.
Remote command:
[:SOURce<hw>]:BB:GNSS:SVID<ch>:GPS:PRERrors:VALue
(etc. for the other GNSS systems)
Start Time Offset
Applies a delay and shifts the pseudorange error profile in time, for example to allow
the receiver under test to calculate a position fix. Suitable start time offsets are then
longer than the TTFF time.
"Start Time Offset = 0" corresponds to the simulation start time, as defined with the
parameter
Observe the pseudorange error plot.

Profile Table
A pseudorange error profile is described as a sequence of up to 10 errors defined in
table form.
