Command
[:SENSe]:EVM:SYNC:BURSt:STATe OFF | ON | 0 | 1
[:SENSe]:EVM:SYNC:BURSt:STATe?
Example
:EVM:SYNC:BURS:STAT OFF
:EVM:SYNC:BURS:STAT?
Preset ON
State Saved Yes
Range Off|On
Annotation PULSE NOT FOUND appears in the corner of the demod result traces if a burst search fails
Search Length
This control enables you to define the time length that the analyzer searches for a
burst.
Remote Command
[:SENSe]:EVM:SYNC:SLENgth <time>
[:SENSe]:EVM:SYNC:SLENgth?
Example
:EVM:SYNC:SLEN 3.0 ms
:EVM:SYNC:SLEN?
Couplings Minimum: Meas Interval / Symbol Rate * 1.2
Maximum: Depends on span
Preset 3.0E-3
State Saved Yes
Min/Max 1.0E-4/9.9E+37
Meas Interval
This control sets the number of symbols that the demodulation will analyze. The
measurement interval and the symbol rate set the overall time record length (in
seconds) that is used by the demodulator. It also indirectly sets the resolution
bandwidth for the various spectrum results. (The ResBW cannot be set
independently.)
Resolution bandwidth and Time length are related by the following equation:
Res BW = ENBW / T
where:
ENBW is the normalized effective noise bandwidth of the Window(see the "FFT
Window" on page 283 topic for more details).
For the pre-demod Spectrum result, T = 1.2*(Meas Interval)/Symbol Rate.
For all other Spectrum results, T = (Meas Interval)/Symbol Rate.
