1. Set the signal analyzer to the default state by pressing the PRESET key.
The R&S
FSVA/FSV is set to its default state.
2. Set the center frequency to 890 MHz, the span to 0 Hz and the resolution
bandwidth to 1 MHz.
a) Press the FREQ key and enter
890 MHz
.
b) Press the SPAN key and enter
0 Hz
, or press the "Zero Span" softkey.
3. Set the reference level of the R&S
FSVA/FSV to 10 dBm (= level of the signal
gen10 dB) and set the attenuation to 20 dB.
a) Press the AMPT key.
b) Enter
10 dBm
.
c) Press the "Rf Atten Manual" softkey.

a) Press the TRIG key.
b) Press the "Trg/Gate Source" softkey and select "Video" using the arrow
keys.
c) Press the "Trg/Gate Level" softkey and enter
70%
.
The R&S
FSVA/FSV shows a static image with the GSM burst at the start
of the trace. The trigger level is displayed as a horizontal line labeled with
the absolute level for the trigger threshold in the measurement diagram.
