Return values:
<Sadata> string
The R&S Signal Generator generates a sensitivity assistance
message as a binary stream.
The returned value of this query for a healthy satellite is a
sequence of integer values. The first integer is the size of the
message in bits to be returned. The remaining, each of which is a
32 bits long block, represents the expected data bits of the navi-
gation message.
The query returns 0, in case an unhealthy satellite has been
selected.
An error will only be reported if an out of range value for any of the
arguments has been selected.
Example:
BB:GPS:ADG:ACQ:SAD? 1,1,3600,1

Response: 0
The selected satellite is unhealthy.
