1 Enter the following measurements (from procedure on page 69).
1kHz_0dB_reference = __________________________ Vrms
1kHz_10dB_reference = __________________________ Vrms
1kHz_20dB_reference = __________________________ Vrms
2 Calculate the dBm value of the rms vol tages.
1kHz_0dB_reference_dBm =
=
10 * log(5.0 * 1kHz_0dB_reference
2
)
__________________________ dBm
1kHz_10dB_reference_dBm =
=
10 * log(5.0 * 1kHz_10dB_reference
2
)
__________________________ dBm
1kHz_20dB_reference_dBm =
=
10 * log(5.0 * 1kHz_20dB_reference
2
)
__________________________ dBm
3 Enter the following measurements (from the procedure on page 71).
100kHz_0dB_reference = __________________________ Vrms
100kHz_10dB_reference = __________________________ Vrms
100kHz_20dB_reference = __________________________ Vrms
4 Calculate the dBm value of the rms vol tages.
100kHz_0dB_reference_dBm =
=
10 * log(5.0 * 100kHz_0dB_reference
2
)
__________________________ dBm
100kHz_10dB_reference_dBm =
=
10 * log(5.0 * 100kHz_10dB_reference
2
)
__________________________ dBm
100kHz_20dB_reference_dBm =
=
10 * log(5.0 * 100kHz_20dB_reference
2
)
__________________________ dBm
5 Calculate the offset values.
100kHz_0dB_offset
=
=
100kHz_0dB_reference_dBm – 1kHz_0dB_reference_dBm
__________________________ dBm (use on page 72)
100kHz_10dB_offset
=
=
100kHz_10dB_reference_dBm
– 1kHz_10dB_reference_dBm
__________________________ dBm (use on page 74)
100kHz_20dB_offset
=
=
100kHz_20dB_reference_dBm – 1kHz_20dB_refere nce_dBm
__________________________ dBm (use on page 76)
