Test setup  Test setup 2, spectrum analyzer mode
Measurement principle The spectrum analyzer is operated as an FM demodulator. A process
controller transmits the start frequency and target frequency via the
IEC/IEEE bus. The spectrum analyzer is triggered by the positive edge
on the EOI line of the IEC/IEEE bus. If the process controller then
switches from the start frequency to the target frequency, the build-up
process appears on the spectrum analyzer screen.
Preparing the measurement  S
ynchronize reference frequencies on R&S SML / R&S SMV03 and
ana
lyzer.
 Establish IEC/IEEE bus and RF connections
 Connect trigger port to EOI line (pin 5) of IEC/IEEE bus.
