Description of command
This command is always a query. It returns the status of the measurement (see chapters 3 and 5).

–4.00 bit to +4.00 bit Number of bits 0 bit V2.15
Description of command
This command defines an offset time in ¼ bit units by which the burst is shifted relative to the time axis and the
tolerance template.

B600 500 kHz Gaussian filter
600 kHz bandpass filter G500 for GMSK modulation
B600 for 8PSK modulation – V3.05
Description of command
This command selects the measurement filter for the P/t measurement. The default filter setting differs for the
two modulation schemes.
Test Configuration
The commands of the following subsystems determine the parameters of the signal power measure-
ment. They correspond to the
Power Configuration popup menu. For a detailed explanation of the dif-
ferent power tolerance templates defined in the GSM standard see chapter 4.
Subsystem POWer:CONTrol
The subsystem POWer:CONTrol defines the repetition mode, statistic count, and stop condition of the
measurement. These settings are provided in the Control tab in the popup menu Power Configuration.
