To what level will you adjust the 700 Hz test signal at the TLP?
The front panel of Wave Analyzer Model 302A (appendix A, section V,
figure 5) carries a switch marked SCALE VALUE. The function of this
switch in the RELATIVE position is to
allow measurement of levels in dBm0.
eliminate the need to calculate relative levels.
assure calibration of the meter at the TLP signal level.
permit measurement of the signal level at the output of the REF
Assume that the normal level at TLP is changed from -12 dBm to -15
dBm, and the second harmonic level is -42 dBm.
Your report should
show that parameter S3
cannot be met because
cannot be satisfied because the test tone level is no longer -10
has been satisfied because the maximum permitted relative level
in dBm0 is within tolerance.
has been met because the increased tolerance results from the
rise in test tone level from -12 to -15 dBm.
Assume that the two frequencies selected for an intermodulation test
are 1,000 Hz and 1,125 Hz.
You should tune the wave analyzer to
