Frequency Response Measurement (60 MHz to 2.5 GHz)

48. On the spectrum analyzer, key in TRACE B LVIEW), TRACE A
a marker on the highest point on the TRACE B waveform.
Record the amplitude and frequency for this maximum point in
-8.80 dBm.
49.
On the spectrum analyzer, use the DATA knob to position
a marker on the lowest point on the TRACE B waveform.
Record the amplitude and frequency for this minimum point in
than - 11.20 dBm.
50. On the spectrum analyzer, press MARKER [al and use the DATA
knob to position a second marker
TRACE B waveform. Flatness (total peak-to-peak amplitude
deviation) of the displayed trace should be less than 1.20 dB.
On the spectrum analyzer, key in
