We moved the EOM drivers from under the PSL table to the bottom of the PSL-R2 rack. The setup itself is still the same until we get the RF combiner/amplifier. Before connecting back to the EOM, we remeasured the RF power using the same settings of 23.4 dBm and 27.0 dBm for 9 and 45 MHz, respectively. As a comparison, we also give the numbers from Koji's alog 41435.
Frequency | old alog 41435 | @rack PSL-R2 | @ EOM | Cable loss | Difference |
9.1 MHz | 23.56 dBm | 23.49 dBm | 23.33 dBm | 0.16 dB | –0.07 dB |
24.07 MHz | 24.60 dBm | 25.33 dBm | 24.90 dBm | 0.43 dB | +0.30 dB |
45.5 MHz | 23.76 dBm | 23.84 dBm | 23.48 dBm | 0.36 dB | –0.28 dB |
118 MHz | 9.84 dBm | 10.22 dBm | 9.66 dBm | 0.56 dB | –0.18 dB |
The cable loss for the 24 MHz signal seems a little high and might be due to an imperfect VSWR. Otherwise, the RF levels are close, but the RF phases will have changed.
