<SampleRate>
This command sets the final user sample rate for the acquired I/Q data. Thus, the user
sample rate can be modified without affecting the actual data capturing settings on the
R&S
FSWP.
Note
: The smaller the user sample rate, the smaller the usable I/Q bandwidth, see
Chapter C, "Sample rate and maximum usable I/Q bandwidth for RF input"
Parameters:
<SampleRate>
The valid sample rates are described in
and maximum usable I/Q bandwidth for RF input"
*RST:
32 MHz
Default unit: HZ
Manual operation:
See
TRACe:IQ:TPISample?
This command queries the time offset between the sample start and the trigger event
(trigger point in sample = TPIS). Since the R&S
FSWP usually samples with a much
higher sample rate than the specific application actually requires, the trigger point
determined internally is much more precise than the one determined from the (down-
sampled) data in the application. Thus, the TPIS indicates the offset between the sam-
ple start and the actual trigger event.
This value can only be determined in triggered measurements using external or
IFPower triggers, otherwise the value is 0.
Return values:
<TPIS>
numeric value
Default unit: s
Example:
TRAC:IQ:TPIS?
Result for a sample rate of 1 MHz: between 0 and 1/1 MHz, i.e.
between 0 and 1
μ
s (the duration of 1 sample).
