:TRIGger<1|2>[:SEQuence]:SYNChronize:ADJust:SLOT -100
µ
s to 100s
This command defines the correction value for the time offset between the frame trigger and the
midamble of the slot selected, without influencing the correction values of the other slots.
This correction value is necessary in order to conserve the exact time relation between the trigger
event and the midamble of the slot in question in cases where there is no midamble triggering. The
value set is corrected by means of the calculated offsets of the other slots and used as a base value
for the correction of all slots.
Example:
":TRIG:SYNC:ADJ:SLOT 30us"
Features: *RST value: -- (depending on slot selected)
SCPI: device-specific
Modes: BTS
The numeric suffix in
TRIGger<1|2>
is not significant.
:TRIGger<1|2>[:SEQuence]:SYNChronize:ADJust:SLOT:AUTO ONCE
This command defines the correction value for the time offset between the frame trigger and the
midamble of the slot selected. The value set is corrected by means of the calculated offsets of the
other slots and used as a base value for the correction of all slots.
This correction value is necessary in order to conserve the exact time relation between the trigger
event and the midamble of the slot in question in cases where there is no midamble triggering.
Example:
":TRIG:SYNC:ADJ:SLOT:AUTO ONCE"
Features: *RST value: --
SCPI: device-specific
Modes: BTS
This command is available only in conjunction with option GSM BTS Analyzer, FSE-K11, and with
option Vector Signal Analysis, FSE-B7. The numeric suffix in
TRIGger<1|2>
is not significant.
:TRIGger<1|2>[:SEQuence]:SYNChronize:SOURce FRAME | TSC
This command defines the trigger reference point for measurements in the time domain (carrier
power, power vs. time). The frame trigger of the base station or mobile may be selected as well as
the relation to the midamble (TSC) of the slot to be measured.
Example:
":TRIG:SYNC:SOURce TSC"
Features: *RST value: FRAME
SCPI: device-specific
Modes: BTS, MS
This command is available only in conjunction with option GSM BTS Analyzer, FSE-K11, or GSM MS
Analyzer, FSE-K10. The parameter TSC requires in addition the option Vector Signal Analysis, FSE-
B7. The numeric suffix in
TRIGger<1|2>
is not significant.
