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.
Remote command:

Profile Table
A pseudorange error profile is described as a sequence of up to 10 errors defined in
table form.
"Time"
Reference time of the error.
The value is set relative to the sum of the simulation start time and
the
.

REFerence
(etc. for the other GNSS systems)
"Value"
A positive or negative pseudorange error.
The last "Value" is repeated constantly.
