Programming a Sequence

Use one command for first acquisition 1 setup

You can use one command to set up all the Acquisition parameters as follows:

:SENSe:LSEQuencer:ACQuire1:SETup

GSM,PGSM,MS,1,1,0,LOW,0.2ms,15.99ms,VIDeo,-10,0,NONE,-20

which sets up Acquisition 1 with the following

• Radio standard: GSM

• Radio band: PGSM

• Device type: mobile station

• Channel number: 1

• Number of averages: 1

• Peak power: dB

• Instrument gain type: LOW

• Transition time: 0.2 ms

• Acquisition duration: 15.99 ms

• Input trigger type: Video

• Input trigger level: -10 dB

• Input trigger delay: 0 ms

• Output trigger: NONE

• Instrument gain “LOW” value: -20 dB

Use one command for first analysis interval setup

You can use one command to set up the analysis interval parameters as follows:

:SENSe:LSEQuencer:ACQuire1:ASTep1:SETup 0ms,0.533ms,19,-5

which sets up Analysis Interval 1 with the following

• Analysis step offset: 0 ms

• Analysis step interval: 533 ms

• Measurement bitmap: 19 (equivalent to binary 10011), which gives results for the following

measurements:

— Basic Transmit Power

— Basic Frequency and Phase

— EDGE Power vs. Time

• Expected power at the DUT output: -5 dB
