10.3 Output Level Accuracy and Flatness
10-6
<Check> : Output level accuracy (under the output obtained in Step above at 50
MHz) ( 0.5dB within a temperature range of 23°C to ±5°C)
For OPT 11, OPT 13 or OPT 14 , the above output accuracy is guaran-
teed using TEST PORT 1.
For OPT 12 or OPT 13, add 5.7 dB (of the 50Ω to 75Ω conversion adapter
loss) to the output level.
For BG (OPT 12), -6.7 dBm ±0.5 dB
For CG (OPT 12 or 13), -11.7 dBm ±0.5 dB
10.3.3 Flatness
Preparations for measurements using OPT 12 and OPT 13 (acquiring frequency characteristic
data of the 50Ω to 75Ω converter adapter)
Measure the frequency characteristic of the 50Ω to 75Ω conversion adapter as shown
in Figure 10-3.
Define the peak to peak value of the frequency characteristics as X dB.
