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:
<Offset> 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 μs (the duration of 1 sample).
Usage: Query only
Manual operation: See " Trigger Offset " on page 57
TRACe:IQ:WBANd:MBWidth <Limit>
Defines the maximum analysis bandwidth. Any value can be specified; the next higher
fixed bandwidth is used.
Parameters:
<Limit> 80 MHz
Restricts the analysis bandwidth to a maximum of 80 MHz.
The bandwidth extension option R&S FSWP-B320 is deactiva-
ted.
TRACe:IQ:WBANd[:STATe] is set to OFF.
160 MHz
Restricts the analysis bandwidth to a maximum of 160 MHz. The
bandwidth extension option R&S FSWP-B320 is deactivated.
TRACe:IQ:WBANd[:STATe] is set to ON.
