Mode and Measurement Parameters
It is possible, in Sequence Analyzer mode, to run certain measurements which belong to other modes
(such as the EDGE/EVM mode). For example, the EDGE EVM measurement, which is one of the
measurements featured in the GSM/EDGE mode, can also be run in Sequence Analyzer mode.
NOTE Settings for a measurement, or for the mode it belongs to, are not changed by entering or
exiting Sequence Analyzer mode. When you set a parameter for a measurement or mode,
the parameter retains that value until you make another specific change to it, regardless of
whether the test set is placed in Sequence Analyzer mode or in the native mode of the
measurement. (Returning to a previous mode does not restore previous settings.)
The present chapter describes parameters that apply to a measurement mode and all of its measurements,
and can be changed from within the Sequence Analyzer mode (by remote command only).
For information on parameters that pertain to a specific measurement within a measurement mode, and
and be changed from within the Sequence Analyzer mode, see the following chapters:
• Chapter 13 , “GSM/EDGE Programming Commands,” on page 181
• Chapter 14 , “W-CDMA Programming Commands,” on page 201
• Chapter 15 , “cdma2000 Programming Commands,” on page 225
• Chapter 16 , “1xEV-DO Programming Commands,” on page 239
• Chapter 17 , “LTE-FDD Programming Commands,” on page 253
• Chapter 18 , “LTE-TDD Programming Commands,” on page 273
• Chapter 19 , “TD-SCDMA Programming Commands,” on page 297
The commands used here to set measurement mode parameters (from within the Sequence Analyzer
mode) are almost the same as the commands which would be used outside the Sequence Analyzer mode;
the only difference is the addition of LSEQuencer:<modename> nodes to each command.
For example, [:SENSe]:RADio:PSHape WIDE becomes
[:SENSe]:LSEQuencer:EDGE:RADio:PSHape WIDE.
NOTE “EDGE” (and not “GSM”) is used to designate the GSM/EDGE mode in commands.
As explained above, a parameter change which is made in this way remains in effect even after the test
set is no longer in Sequence Analyzer mode. Selecting GSM/EDGE mode would not undo a
GSM/EDGE setting change that was made in Sequence Analyzer mode.
The settings apply for the whole Sequence (not just for a particular acquisition), and should be set up
prior to starting the Sequence.
