Sequence Programming Example
The example used in this chapter uses the GSM radio standard. GSM/EDGE measurements can be made
in the Sequence Analyzer mode only if you have the GSM/EDGE measurement application licensed in
the test set.The SCPI commands for setting each of the GSM/EDGE measurements from inside the
Sequence Analyzer mode are listed in Chapter 13. Changes to these parameters made from within the
Sequence Analyzer mode result in changes to the equivalent parameters in the measurement mode.
The sample sequence, shown in Figure 10-1, shows a simple sequence that can be used to calibrate a
mobile device. It consists of four sets of stepped power sequences, using PGSM and EGSM radio
standards. This section shows you how to build up a program to set the test set up to acquire this data and
provide measurement results. Some of the parameters in the program are set to example values which
you would modify as needed.
The calibration sequence is shown in Figure 10-1 and the associated spreadsheet is shown in Figure 10-2
To allow the test set to make measurements the sequence is divided up into four acquisitions, and in each
acquisition there are 15 analysis intervals. From the spreadsheet you can see that the Measurement
Bitmap value of 10011 sets the test set up to perform the measurements of Basic Transmit Power, Basic
Frequency and Phase, and EDGE Power Vs. Time.
