Command syntax:
[NoOfCoeffs,OvsplFact] = TSWMGetFIRParam(Ndown,
OvsplFact);
Parameter(s):
Ndown
Defines the fractional down sampling factor. Given the
desired sampling rate fs, the down sampling factor is
defined as fs/(395e6/18).
I.e.: The desired sampling rate divided by the native R&S
TSMW sampling rate.
OvsplFact
If given, the specified oversampling factor is used. If not,
an appropriate oversampling factor is used. It has to be 1,
2, 4, 8, 16 or 32.
This parameter is optional.
Return value(s):
NoOfCoeffs
Maximum number of FIR filters coefficients. The number of
FIR filter tabs is given by NoOfCoeffs / OvsplFact.
OvsplFact
Selected oversampling factor.

TSMWGetIQTime
Description:
The function retrieves an estimate of the current I/Q time at the R&S TSMW. The
I/Q counter starts as soon as a connection to the R&S TSMW is established. The
counter counts the I/Q-samples in the native sampling rate of
395/18 MS/s
. It
has a valid bit width of
48 bit
.
The I/Q-time specifies the time that is used to start measurements.
Command syntax:
[ErrorCode, IQTime] = TSMWGetIQTime(TSMWID);
Parameter(s):
TSMWID
Defines the instrument.
