3 Short-Range Comms & IoT Mode
3.2 Modulation Analysis Measurement
The resolution bandwidth is annotated below any spectrum trace.
Remote
Command
[:SENSe]:EVM:SWEep:POINts <integer>
[:SENSe]:EVM:SWEep:POINts?
Example
:EVM:SWE:POIN 501
:EVM:SWE:POIN?
Preset 501
State Saved Yes
Min/Max 21/4096
Annotation Time Length is annotated on the bottom right of Spectrum or Inst Spectrum traces, in units of Seconds.
Time Length is Meas Interval / Symbol Rate. Under frequency-domain demod results, time length is
annotated in units of symbols
Burst Search State
This control enables you to turn burst search on or off.
Remote
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
3.2.8.4 Demod
This tab enables you to set demodulation parameters.
Modulation Format
This control enables you to select the format that is used by the demodulator. The
selection choices include: Offset QPSK, BPSK and FSK 2.
Remote
Command
[:SENSe]:EVM:MODulation OQPSK | BPSK | FSK2
[:SENSe]:EVM:MODulation?
Example
:EVM:MOD OQPSK
:EVM:MOD?
Couplings If the radio standard is not ZigBee (802.15.4), the Offset QPSK and BPSK will be grayed out. If the radio
