QPSK EVM Measurement
Marker
Couple Marker
Toggles the state of the markers to be coupled On or Off. When this function is true (On), moving any
marker causes an equal X-axis movement of every other marker except those located to the polar trace,
and Chip value of the marker located to the polar trace, which is not Off, including Fixed markers.
“Equal X Axis movement” refers to the difference between each marker’s X Axis value (in the
fundamental x-axis units of the trace that marker is on) and the X Axis value of the marker being moved
(in the same fundamental x-axis units). This may result in markers going off screen
See Couple Marker in the "Marker" section for more information.
All Markers Off
Turns off all markers.
Mode WCDMA, C2K, 1xEVDO
Notes Assigns the specified marker to the designated trace.
Preset POLar
State Saved Saved in instrument state.
Range I/Q Polar|EVM|Phase Error|Mag Error
Instrument S/W Revision Prior to A.02.00
Remote Command :CALCulate:EVMQpsk:MARKer:COUPle[:STATe] ON|OFF|1|0
:CALCulate:EVMQpsk:MARKer:COUPle[:STATe]?
Example CALC:EVMQ:MARK:COUP ON
CALC:EVMQ:MARK:COUP?
Key Path Marker
Mode WCDMA, C2K, 1xEVDO
Notes In QPSK EVM, this marker behaves specially. Coupled values are "Chips" of
the markers located to the polar trace, and "X" of the markers located to the
other traces than the polar trace.
Preset OFF
State Saved Saved in instrument state.
Range On|Off
Instrument S/W Revision Prior to A.02.00
Remote Command :CALCulate:EVMQpsk:MARKer:AOFF
Example CALC:EVMQ:MARK:AOFF
