1. The 11975A Amplifier, or a similar amplifier, can be used to provide sufficient LO power (14 to
18 dBm) to the mixers. Leveled power capability of 16 dBm, as is available with the 11975A, is nec-
essary to achieve the maximum amplitude accuracy with the mixers. Assuming the 1 meter cables
supplied with the instrument are used, only the 8566B LO output requires amplification. However,
if longer or lower quality cables are used LO amplification may be necessary.
2. Typically ± 2.5 dB with LO supplied by 8566B Spectrum Analyzer, 11975A Amplifier set to
16 dBm, and P/N 5061-5458 SMA cables.
