10.4.4 Example 4: Remote automobile key (ISM band)
Only the frequency range 433.05 MHz – 434.79 MHz can be specified for
remote automobile keys using the ISM band. The following describes how
the other parameters can be determined:
1.
Switch to
Spectrum
mode and activate the marker function:
– Find Fcent: Set the marker to the maximum (here: 433.942 MHz).
– Find RBW: Set markers A and B: Bandwidth is the difference between
the two frequency points (here: > 16 kHz).
2.
Switch to
Time Domain (Scope)
mode.
3.
Settings in the example:
– Fcent = 433.942 MHz
– CBW = 100 kHz
– Measurement = High Resolution Scope
– Time Span = 10 ms
– Time Resolution = 1/CBW = 10 µs
Find Fcent
Find RBW
