Measuring the Edges of a GSM Burst with High Time Resolution
Due to the high time resolution of the R&S
FPL1000 at the 0 Hz display range, the
edges of TDMA bursts can be measured precisely. The edges can be shifted to the
display area using the trigger offset.

The measurement is based on the example
"Measuring the Power of a GSM Burst
1. Switch off the power measurement.
a) Press the [MEAS] key.
b) Select "Zero Span".
2. Increase the time resolution by setting the sweep time to
100
µs
([SWEEP] >
"Sweep Time Manual" ).
3. Shift the rising edge of the GSM burst to the center of the display by defining a trig-
ger offset.
a) Press the [TRIG] key.
b) Select "Trigger Offset".
